T17E firmware is now available

Hi everyone ! now releasing S17+ firmware with only 1% fee !

Hi, to my knowledge, only firmware before 2020 can be unlocked by a remote utility, so asicTO utility (works very well) or Awesome miner (also works very well via the command "Send custom:" unlock "to unlock ssh) ...

We have also experimented with a bitmain firmware from 2020/04, and the unlocking worked very well with the SD card despite the recommendations, but to be taken with a grain of salt, we only tried the T17e ... You can try it. SD card in this case, you do not risk anything. at worst nothing will happen and you will keep the firmware currently installed. PS: "my" SD card file is compatible with all 17 series without exception, and also for all minors with the C43 control card (for exemple : s9k, s9se, Z9/11 and more).

Regarding my firmware, try to unlock it with a utility, and try to install my firmware, if that doesn't work you must use the SD card files that I placed at your disposal in the first post, once the firmware is installed, if it does not suit you, no problem to go back (Philipma1957, Favebook, and me will confirm you) it is to say install bitmain, or vnish, or other!

Bruru : If you want help, i need screen of your ("System / Overview") for i understand what firmware you use actualy

I remind you that I am available for any request about my firmware, and I am as transparent as possible, do not hesitate to send me a PM if you want a quick response;)


Ps : HS , today was the big day for me! very stressed, a great first for me, this morning I had an operation for the removal of the gallbladder. Everything is fine, everything went well, I hope this will continue! I have 30 days of rest to respect, no physical effort.

Awesome Miner firmware is nothing but a re-branded version of Vnish firmware, so I highly doubt that they can edit the firmware in such a way, in fact, even the "unlock" tool is from Vnish IIRC, with that being said, I was personally able to migrate from Vnish (AowsomeMiner version as well as Asic.to) back to Bitmain and the other way around, this works on S9 as well as T17, I am not sure about the other versions but I can only assume they all are the same.


As far as I know, only Bitmain locks your miner, I have only tried Vnish and BO firmware so I can't speak about the other dozen firmware out there, but I have not heard about any other firmware except for Bitmiain's that would lock the miner, of course, absence of evidence isn't evidence of absence.

You can be right but it is not guaranteed. When you sd card flash with this firmware, your machine is unlocked. I tried flashing Vnish back and forth and it worked fine.

However, I am not sure if awesome miner unlocks your device. They might even unlock it just to flash their firmware and then lock it so you cannot flash any other firmware. Smart they are...

Ok, So unlocking the firmware (what i did) with an other firmware does not work? I thought by removing the Bitmain firmware the device is unlocked.

you need to go to location.

you have to flash an sd card that unlocks the firmware.

bring the sd card to the machine unlock firmware

then burn in new firmware using a pc with downloaded file.

op did this with my t17 and my t17e and my t17+

if you want to go back to older firmware

unlock the machine with the op's unlock sd

the load firmware with file on your pc.

I have delayed testing his s17pro firmware since I have access to no s17's until I drive up to Clifton nj from Howell nj.

When I try to install the firmware using the Awesome miner firmware on the S17pro it gives me the message " no signature ".

How can we fix this without having to go to the location :-)

Hi all, i edited first post, for add S17 / S17pro firmwares, this firmware is compatible with S17 and S17pro models.

Is now available, with only 1% devfee !

Please let your comments !!! 

My mom in law had it years ago it can be very painful.

I got the t17+ to do 62.2 th for more then tens days in a row.

it reads fail as it should do 62.6 th at the freq and the volts it is set to.

but it is a case of the unit being a poor unit.

I was able to order another s17pro. when i get it we can work on that one.

so far i am really happy with your mods. they are pretty good.

Hi, thank you for worrying, it touches me , actually I spent a night in the hospital for a "gallbladder?" bilary. I'm going a lot better, but I have to have an operation for an ablation in early October, I lost all confidence: s and a can in panic but I must do it ...

Regarding my firmware, thank you for all these details! and time to test all this! have you been able to raise power? efficiency?

I would also like to have the opinion of the community concerning the costs, their opinion interests me, I should perhaps lower them to convince more people?

Thanks again;)

Some good news it looks like the t17+ miner i have always fails but it works.

ie set to freq 500 should do 47th it does 46 or 45 even if you boost volts.

but set to freq 685 should do 59th it does 57 but you can undervolt it a bit.

so my unit on stock could do 62 th and crash and crash and crash and crash.

it is doing 59th slight undervolt and not crashing.

So it is more likely a gear issue and not a firmware issue.

I will post some screen shots. in a few.

these are full size

Same here. Biggest leap of trust I had was giving thierry access to my gear. Otherwise, I (like you) wait until others test them.

Check newest update from taserz:

@ thierry4wd. I hop you get out of hospital soon. As you know my wife got sick early in the year and she is getting better.  So I hope the same for you.

It is night fall I am going to try a different setting on the  t17+

As for good firmware bad firmware , dishonest firmware developers and honest firmware developers all for are out there.

My testing gear runs on a completely different network using optimum

while my mine is on Verizon.  Separation to the max .

All weird gear I buy runs on the optimum cable carrier. All new firmware runs there.

So if there is a hack it would less then 10-15% of my gear.

Anyone with 2ph of sha 256 gear or tons of other asics must consider some security.

big farms have multi networking. and should effort safety. smaller guys reading about this firmware should consider setting a test network via dual routers or something. to keep not
Oem firmware isolated from other gear.

That said

1_ hope thierry4wd gets better faster than my wife has taken
2_ the t17 is very good and has a 1% fee I give it my full recomendation
3_ the t17e is a work in progress
4_ the t17+ will need more testing I will try it tonight. and in a week or so I will try the other t17+

trying 675 freq and 1890mv

Sorry to hear that, hope you are feeling better now, stay strong and get well.


This was my initial thought, I think a fair test should be done on a good stable gear for further analysis.


I am paranoid when it comes to custom firmware, It would be unlikely for me to test anything that hasn't been tested intensively by others unless I do trust the dev very much, I also heard the Vnish (AwesomeMiner/ Asic.to) are working on MicroBT firmware, I heard this a few months ago and no updates since then, I think it isn't about how hard it is to make, it also has to do with the fact that MOST gears in the market were Bitmain gears, also the fact that MicroBT gears usually come with different working modes unlike most of the Antminers, it makes reduces the need for custom firmware.

But as I said, I would love to see Firmware competition just as much as I love seeing hardware competition.

Well Like I said the t17 is next to perfect 0 complaints .

The t17e the volts mod  and the fan mods work and it saves watts thus crashes less than the un modded t17e.

So it is incomplete but good for what was done.

The t17+ undertunes shows fail almost all the time.

I keep playing with it but can not get a good setting so far.

I did have a poor running t17+ So it could be the units issues not the firmware. I will try some more later today when the sun sets  (3 hours from now)

I have heard that Asic.World finally cracked the MicroBT gear and that the firmwares are ready. However, with what happened between chipless and him/them, I'd be careful before installing any of their firmwares as they are quite new to this afaik and they have no real reputation here.

Chipless might be working on MicroBT firmwares as well, nothing is for sure, however, we could ask him on one of his threads.


I hope you get better thierry, as soon as possible. I might give you access to my S17 Pro and S17+ soon (as soon as I write down all the profiles from taserz firmware - I really do not want to waste month(s) again tuning them).

Hi, first of all thank you for the very helpful review! at the moment i'm very ill, staying in the hospital, i don't have too much time or strength at the moment: but i'm trying to follow a little ...

Concerning the T17 +, I am very surprised, because the mod is the same as on the T17, and I did not see any problem with it, can you tell me more about this strange behavior? I am very curious about this because very surprised!

I think I remember you mentioned about one of your T17+ that has a board disappear sometimes and then it shows up, is that the same gear? anyway since this gear is known to have been instable judging the firmware on it won't be fair at all, let's wait for someone else who has a proper working T17+ and is willing to test the firmware.

I guess since you mentioned that both the T17 and the T17e firmware are doing good then I suppose the T17+ should work just fine on a proper machine, it seems like thierry finally cracked the 17 series secret, I hope he and all the other firmware devs start looking into MicroBT gears, there is no custom firmware for all the MicroBT gears, although MicroBT has sold many more gears than Bitmain did for the past couple of months.

The t17 is great. I would tell anyone to try it.

The t17+ is working poorly. But to be fair it always worked like shit so I am not sure if it is a bad unit.

The t17e has volt and fan mod. He has yet to fully fix freq. But I have been busy.

I will mod my second t17 .

I will mod my second t17e even if it is only volts and fan.

Phill, please don't forget to update your T17e,T17+ and T17 results? Thanks for keeping the updates coming.

I would also like to hear from thierry4wd why does the T17+ firmware differ from the T17 and what are these "odd behaviors", does this have to do with the fact that the E series uses less efficient chips and comes overclocked?

I believe that the worst 17 series is the "E" versions, and then the "+" versions, the S17 is also a bad gear, the only good gear IMO is the S17 pro and T17 is not too bad,  I also think that most of these gears run way more stable when underclocked rather than on default settings.

it would run in my garage for a few days.

I just moved the t17 the t17+ to clifton and they are online with the t17e

so far t17 great highly recommended software.

I am looking to test the t17+ longer as it has some odd behavior.

the t17e has only voltage and fan control it works well.

Once all three units run over night in clifton I will post back.

That's about 17% more efficient which isn't bad at all, I also assume you can get away with 30-40% less fan speed so that will get you another 20-30 watts of the initial consumption plus the fact that it makes the miner quite enough, you might still need a few physical modifications on miner itself, probably make a whole or two like thierry4wd's mod, or change these loud fans to some Delta fans since they make a lot less whining pitch.

How long has this custom firmware been running stable for?

Okay took me a while to understand terminology.

Also we are doing 3 units.

t17
t17 +
t17 e

Failed means it is under tuning. I e it should do 50th and does 49 th

tune okay means it is at or over  the mark.

I am going to fully rate and test the t17 today.

after 10 minutes my latest test with a good meter says tune is okay.
this is full size click to link: https://i.imgur.com/ljcARud.png

it projects that it should do

36018
36583 is what it did after 10 minute test that is higher then projection so tune is okay

this unit is set to freq 605 fans at 38% and mv at 1645 I did this to keep noise levels acceptable for my wife.

full sized image: https://i.imgur.com/mhNVTP8.png

Now I have an hourly meter that does kwatts

at 4:50pm it read 91.28

so 5:50 pm = ?

it should do 40th at 2200 watts = 55 watts a th

since I am at 36.5 th x 55 = 2007-2008 watts

so the meter should move to 93.28 or 93.29 at 5:50

I have found a 10 hour read to be very accurate for power use.

temps are really good for 38% fan speed.

t17 specs are from here: https://support.bitmain.com/hc/en-us/articles/360020445993-T17-Specifications

I am running the t17 at viabtc

full size link: https://i.imgur.com/5mwhmkO.png

missed the 1 hour meter read.

the 2 hour read is as follows

94.98 6:50pm
91.28 4:50 pm
  3.70

3.70 kwatts in 2 hours =  1.85 kwatts or 1850 watts

36410 gh so

1850/36410 = 50.81 watts a th.  that is well under bitmains 55 watts a th

and viabtc says the hourly avg is 37.26

better then the gui.

if the viabtc number holds you get. 1850/37260 = 49.65 watts a th

that is good. if it keeps it up.

I will check back and do more watt readings.

100.46 at 9:50 this is a  1836 watts per hour avg for 5 hours.
 96.80  at 7:50  this is a 1840 watts per hour avg for 3 hours
 94.98  at 6:50  this is a 1850 watts per hour avg for 2 hours
 91.28  at 4:50

1836/36396 = 50.44 watts a th

pool shows 37.37 th or

1836/37700 = 48.70 watts a th

this firmware charges 1% so far it appears rate has been 1.136%

I will show calculations I did for that.

My garage got too hot and with lowered fans unit was too warm.

So at 11:52 I rest the gear at lower freq and lower mv

my meter read 103.79 kwatts last night and now reads 115.69 kwatts

so I used 11.90 kwatts from 11:52 to 7:52 or 11.9/8 = 1.4875 kwatt an hour.

the gear at freq 500 and  mv of 1635 tunes okay does 29.828th on GUI and 30.08th on viabtc pool

so 1487.5/29.828 = 49.869 watts a th. vs 55 watts a th at bitmain firmware
and 1487.5/30.080 =49.451 watts a th on pool stats

so a good improvement in efficiency is happening on the 36th to the 30th levels of hash

I really like the auto fan setting at this lower hash rate of 30th the fans are running at 2520 to 3120. This miner in my garage with a minimum of sound proofing can be used to solo mine.  As for fees

it did 7172 shares over last 8 hours.

7037 at  32.8 diff
1 at    4.1 diff
108 at   4.1 diff
26 at 65.5 diff

the bolding is the dev fee

7037 x  32.8.  =       2308136
      1 x.  4.1.  =                41
  108 x.  4.1.   =            4428
    26 x 65.5.   =          17030
total adjusted shares 2329635

fee is  17030/2329635 =. 0.0073101 or under 1% after 8 hour test that will alter and flux a bit as he does a take out every 2 hours so you can go over and under the 1% fee depending on when you do a reading of the shares

I really like the t17 firmware especially with a 1% fee
you can really do some low settings with it if you want it to solo mine on solo.ckpool.org

It will get really quiet. I won't be able to do high settings until I go to the farm with it.

But I am very tempted to set it to freq 300 and 1620mv
I would like to see if fans drop to under 2000 at that setting along with watts under 1000

this firmware will make your t17's into space heaters that mine solo if those setting work.

Once I move the gear to Clifton I can go with a setting like freq 670 and 1680mv  that should do stock speed but save watts and keep temps lower.

120.14 kwatts at 10:52
103.79 kwatts at 11:52. an 11 hour reading

16.35 kwatts

16.35/11 = 1.486 kwatts to do 29.830. or 49.827 watts a th.

I get 29.97 th at the pool or  49.58 watts a th

dev fee was

9209.    x  32.8         3030552
      1.   x    4.1                  41
  108.    x.  4.1               4428
    36.    x. 65.5             23580

23580/3058601 =   0.77% fee

I am done testing it at:

auto fan
freq 500
1630mv

next test will be

auto fan
freq 360
1540 mv

I will then move to the t17+

I will do full speed tests on the t17 when I bring gear to Clifton NJ

we are doing 21.075th
at freq 360
and 1540mv
fans are 2400__2400__3120__3120

chip temps are

54-60-52-58
52-62-53-60
54-59-51-57

room is hot about 90f or 32c

Meter reads
120.72 kwatt at 11:20
122.67 k-watt at   1:20

I will get back to power reads.

that is 1.95 /2 =  .975 k-watts

so 975/21.073 = 46.2677 watts a th  quite a bit lower then stock 55 watts a th.  of course it does 21th but it makes the t17 a quiet  space heater for the winter.

The t17 mod is very effective on all my under clock and under volt tests.

126.00
5:15

131.35
11:20

Great work phill, why does it say "failed" when the miner is hashing and everything seems to be normal? what criteria does the firmware use to evaluate what is a good tune vs bad tune?

Also, I am very interested in seeing how are you doing with power consumption comparison, assuming your goal is not a better temperature and you aim only for efficiency, would you still recommend the firmware?

Testing is starting

Okay testing t17 and t17+

We are also still playing with t17e as we have fan and volt control but no freq control.

Learning curve on under volt under clock.

but the next week will be 90f every day so now is the time to do it.

I set the t17  to freq   580 volts   1640mv
I set the t17+ to freq 585   volts 1660mv



here is a good tune and a bad tune.  it suggests raising 10 mv from 1660mv to 1670mv.  I did 1665mv

I stand corrected. Haven't checked for while...

Vinish uses a different structure called "parallel mining" so 2% (or whatever the fee is) of your hash rate always mines to the dev pool as long as your gear is online and hashing, so this is a completely different way of handling the dev fees, at least this is what they claim to be using and I have no evidence to confirm nor deny this claim.


That's pretty fair unless parallel mining is a thing then doing 24/2/2.5mins is pretty fair, you only get your 30 mins if the miner runs for 24 hours, this is way better than some other custom firmware devs who try to get their fees within a couple of hours.

Thank you so much for your explanation, and good luck.

Hi, regarding the testing of my firmware, I appreciate your commitment to do a review, however, for the T17 and T17 + models I would prefer that you use the public link, so that the review is as close as possible to reality

Of course, the T17E is another topic for the moment, and as promised to those who reached out to me to develop the tests, thereafter, you will have access to my firmware without dev fee, if at all are suitable, and that you want to keep them of course;)

I am heading to Clifton NJ.

I will move the t17 the t17+ to the same test network as the t17e.

I will give access to thierry4wd he will set them up and I will test and post results.

I will soon be able to show overclock on the t17+ and the t17

and we are still working on the t17e so that it can do more then just undervolt.

In the interest of transparency my fee for my work will be my modded gear.

1 t17
1 t17e
1 t17+

will not pay a development fee.

I am hoping to get a lot set up tommorrow and I will prep today by loading sd cards to load into the gear.

At the moment my teamviewer access to  my farm is down. I do have access to the two t17e units. as they are on the test network.

the vast majority of my gear is on the verizon network not the optimum network. When I get there I will figure out why teamviewer is down on the verizon network.

I want to talk about a service or firmware mod like this. It is needed due to bitmain locking voltage fans and freq on the gear.

So think of this from the developer theirry4wd viewpoint, bitmain can end his business with a simple new firmware upgrade.  This is why he found it hard to sell it as one time fee. Pay 100 or whatever and then bitmain does new firmware with options. Miners did not want to go one shot fee. A fee every two hours works.  I would think if he has enough people using it he could alter fee to 1.5% .

I am hoping to get all this setup for testing tomorrow.

I will need to burn some unlocking sd cards today. Move all units to test network tomorrow. And fire away.

To update just a bit both new and old t17e are running on test network.

the new runs cooler and the fans are slower. At this point in time I can only alter voltage and fans.

The weather in NJ is cooler so the benefit of undervolt is less. These are the two t17e.

Hi everyone, and thank you for your interest!

I will try to answer your expectations as clearly as possible, I am here for it;) and I am as transparent as possible!

Here are 2 screens, which should already answer most of your questions;)



1: Regarding the single payment, for a license without devfee, I realize that it does not interest anyone in reality, or at least a very small minority ... that's why I decided to integrate 2% cost, but in return the download is free, which allows you to test it for free, absolutely nothing prevents to revert to another firmware thereafter (original included).

2: the fees are extracted every 2 hours as you can see, my priority is to make your miner more efficient, not to fill my pockets as quickly as possible as some do (be careful, I do not quote anyone, some custom firmwares are very good too), and by design, the minor switch on the dev fees one can more than every 2 hours, for about 2min30.

3: The beginning of the fees, in fact, when you install my firmware, you will need to play with it a bit (like any other custom firmwares), try new parameters, new freqs, votlages .... and by design, each time you press "apply" news settings, the count of these 2 hours is reset to zero, by design, for as long as it takes you to polish it, you will still be on your main pool.

4: Confirmation of fees, look at the 2 screens, I will round off the figures, the miner works at 49.5th, if you do (49.5 / 100) x2 = 1 ... now look at the pool report, over 24H, you have 1th extract, which confirms that you have 2%, and no more.

Now look at the minor side, understand that it is necessary to make the report with the "DiffA" (and not the "Accepted"), because the difficulty of the pools comes into play in the calculation, a pool with 52.5K will have more shares than 'one at 65.5K (to use our example).

Please calculate ... we have "1763283525" on the main pool, and "35061760" on the dev pool side, if you do this calculation:

(1763283525/100) x2 = 35265670.

See that we are very close to "35061760", in this case, in reality the miner has extracted very slightly less than 2%, that is explained, the miner extracts the dev pool, and whatever happens, he Switch back to the pool, even if he hasn't finished his share, and therefore, by design, if a share takes 10s to do so, it will be lost.

I hope I have been the most transparent with you, and if you have new questions, I will answer them without problems! Thank you.

PS: I will modify the first post to add the other firmware. I am also awaiting the test from Philipma1957, who I know, that this self good or bad will give as much detail as possible , I will add a link for the T17 by tonight, with a charge of only 1%.

I totally agree with you mikeywith, but afaik there hasn't been a better solution with dev fee other than this. IIRC Vnish uses same structure to get his dev fee. I highly doubt it runs dev fee every hour (this would be way too often IMHO) and I doubt it runs dev fee as soon as you run it. But as I said, we should wait for official statement from thierry4wd.

This is a bad way of going about, depending on when the dev pool is initiated, it could be a lot more than 2% and of course, could be less (with no direct benefit for the miner) this switching structure "assumes" that the miner is on 24/7 which isn't always the case.

Now in a perfect scenario, if the total fees are 30 mins worth of mining, your gears run for 24/7, and the dev pool is on for 1.5 mins every hour (1.5*24 = 30 mins).

if the dev is greedy, he wants to get the 30 mins as fast as possible, they might want 5 mins per hour, even if they were fair with 1.5 mins that starts at minute 00 of every hour.

Time From : Time To
00:00  : 01:00   = 1.5 mins
01:00  : 02:00   = 1.5 mins
02:00  : 03:00   = 1.5 mins
03:00  : 04:00   = 1.5 mins
04:00  : 05:00   = 1.5 mins
05:00  : 06:00   = 1.5 mins

at 5:30 your miner reboots, it goes back online at 5:35, the dev will take another 1.5 mins, a few reboots here and there add up and if you have a dozen gears, it will get even worse.

If the dev is greedy and wants 5 mins an hour to collect the 2% in the first 6 hours of mining, it gets ugly.

00:00  : 01:00   = 5 mins
01:00  : 02:00   = 5 mins
02:00  : 03:00   = 5 mins
03:00  : 04:00   = 5 mins
04:00  : 05:00   = 5 mins
05:00  : 06:00   = 5 mins

so far you have paid 30 out of 30 mins, you would expect until it's 00:00 next day the dev should get nothing, but this is not how it goes since the dev can't keep a record of this info, all they have is your miner run-time and thus when your miner goes back online at say 07:00 , you will still pay another 30 mins and that makes the dev fee 4% instead of 2%.

It all boils down to how these fees are taken, not sure if you remember Dollemizer firmware for S9, was one of the very early custom firmware for S9, the fees were way higher than advertised not just because they were lying about it, but because of how they collected it,  IIRC that firmware was set to start mining to the dev about 2-3 mins after the miner boots up for about 3-5 mins, at the end of the day if for whatever reason you reboot your miner somewhere after the initial 5-6 hours of them attempting to collect all fees upfront, you end up paying twice, I can't recall all the details but I know dev fees were way higher than what they seemed to be, not sure if the devs came up with some solutions to this issue or not.

Having said that, I am not accusing thierry4wd of anything,in fact, I do trust him a lot and I am sure he would try to structure this in the fairest way possible.

I think it was changed due to lack of people interested in it. But would love to hear actual reason here from him.

It mines for Y amount of time every X hours so it mines total of 2% of 24h which is ~30min. So to answer your question directly, yes, it stops mining on owner's pool for brief amount of time.

Thierry I see that you have changed the pricing for this firmware from a fixed fee to a 2% dev fee, mind at first explaining the reason? was it hard to make the firmware run on certain miners and you were worried about piracy?

Also, how does the firmware mine to the dev pool, is it parallel mining where 2% of the hashrate is always directed to your pool or the miner stops from mining to the owner's pool for 2% of the time?

So far his firmware has worked fine. I am going to Clifton to test two other t17 and t17+

I need access to them as I have two networks.  one from  optimum and 1 from Verizon I will run his on 1 network as a precaution then shift to my other network where most miners are.

Hi all, i have updated my first post, is now available for all, free download .

the nice thing is it readjusts so it you set to 75% and it is too hot they go upwards towards 100% and get there mid day then drop down to 75% when the sun sets.

the oem firmware is too aggressive.

so they run very near 100% 24/7

so the oem fans will wear out faster and waste power . it saves more then you think since four fans use close to 100+ watts at full speed.

so far i don't see ill effects from setting fans at 75% or 80% or 90%

as for 1680 vs 1690 vs 1695

testing will tell.

the stock gear is pushing 1730mv at or close to 100% fans.

it is not hashing faster
it hashes a fraction less then the new firmware set at 1680

the stock gear in a warm room like mine can not speed fans to cool better because fans are full spped on it.

so the stock gear downclocks  freq in order to cool it.

if it were really cold like 0c outside the stock firmware would be okay.

right now i bumped the new firmware to just a bit more volts 1695mv. so far the new gear is cooler and hashes higher then the old gear.

as long as it does not drop off 1695mv seems better.

now tomorrow it will get hot. So I will check and see if the 1695 is too high.

I can not change freq yet.  so I have not tried super low volts like 1625 or 1600

I also want to do 24-36 hour tests. so the 1695mv test has about twenty four more hours to go.

I would like to try highest setting I can do maybe 1700mv.

I would like to try lowest setting I can do maybe 1600mv.

As for fans maybe 60% in the winter with maybe 1675mv but that will not be anytime soon.

Won't it be better to test lower values since it's pretty hot there? Anway I would recommend that thierry4d tries to implement an auto-downclock function for when a miner gets pretty hot (temps should be pre-set by the user), and vice-versa for when it's too cool, these should be optional features and not set by default.

I would also suggest you stick to 100% fans, these gears break easily as you are probably aware of by now, so you want them to run as cool as possible, and according to my experience, 25% which is about 1500 RPMs across all 4 fans makes the miner run a lot cooler.

on the storm end we are fully back to normal. i packed the generators into storage. cleaned the brush and branches and can move on to helping wife recover from last winters (covid-19?) damage.

we are now making appointments to a ear nose throat doctor 👩‍⚕️ to address her 7.5 month long post nasal drip. which has hindered full lung recovery from what ever she had back in jan 2020.

i have been pretty much overwhelmed this year.

personal health
wifes health
covid-19 shutdowns = this affects all of us
george floyd = black lives matter protesters this affect some of us.
large tropcial storm= mostly north eastern usa.

been quite an interesting year.

new info 08/11/2020

So it got smoking hot again and results were the old original bitmain firmware crashed

---

so for a hot spot the t17e is a real saver.

the settings of 1690mv and 85% fan save power and prevent over heating of t17e gear.

hashrate just about the same. but do favor the new mod.
errors just about the same.     but do favor the new mod.
rejects just about the same.    but do favor the new mod.

this mod allows fan settings of 85, 90, 100%.  There are more choices I only tested three of them listed.
this mod allows volt settings of 1680mv,1690mv. There are more choices I only tested 2 of them.

It looks like NJ is over the storm damage from last week. I will contact thierry4wd about freq settings

thierry4d asked me to test 1695mv and 75% fan.

I will get back later.

Did thierry4wd make any adjustments after the initial installation?

The custom firmware without a doubt will consume slightly less voltage than the stock, also the rejected shares and hardware errors look a lot better on the custom, I guess in the long test the new one will report a slightly higher hashrate on the pool side a well.

Sorry to hear that things are not going fine in the U.S, are things back to normal yet?

please forgive me for delays on reporting this.

But we lost
power
internet
cable and cell phones.  I simply have not had the time to drive up to clifton and measure power.

BTW I can set fans to 85% fan setting works along with volt setting.

I think sometime this coming week I will get back up to Clifton and measure watts.
I can certainly  work with this on overheating gear.

Don't use the numbers yet as I have not had a 24 hour test.  As clifton has had 2 separate crashes due to the power grid.

Curren settings are

1690mv
85% fan speed

oem settings are

1730mv
100% fan speed

I am hoping to show a 36 hour result  on sunday

---

here is a longer test.

I am going to load full size and leave links to see them.

what is interesting is the old firmware got a bit hot and did auto down clock to not overheat. So the freq is lower for the old firmware.

the new firmware stayed solid at higher clocks and simply runs fine with out a throttle effect.

new screen shot link

the new firm ware/software tweak

has 100% victory in all categories


                 new------------old

hashrate.  53.46th _____ 53.35th.  at the pool where it counts
HW errors.  562 _______ 1469
HW %.     0.0000 ______ 0.0001
Fan.          6000 _______ 5040
temp.       73.33 _______ 75.66.  note: I used average of 3 temp chip

rejected.    9 __________ 91      note : did not fit on the screen shot

So new set to
1690mv 85% fan
old set to
1730mv 100% fan

new wins in every way

Today. it will get hot I will post again

I suspect fans on new will pick up to 100%

and freq will not down clock to keep gear cool

the old freq will down clock to keep gear cool

so new will have another win.

the only thing now test is exact power used. I think I will go to Clifton to check that next Saturday.

Ok so the custom firmware with the current settings is about 4TH less than Bitmain's stock firmware and up to 9 degrees cooler on some chips and average is about 4-5 degrees cooler on the custom firmware, now assuming these run in the same environment this isn't bad at all, what matters more, however, is the efficiency, what is the power consumption per TH on both firmware?

power is back



So if you click the image you will see the power cut to 1680mv lowers hash rate a bit and lowers temps a bit.
errors are close to equal .

fans were set to 90%  volts set to  1680mv.

fans in new test will be 80% volts set to 1690mv.

---

Update I have no power.
No cable.
No internet. Using a smallest generator . So I can keep fridge and a few phones working.
The far. Is back up but I do not have team viewer access .  Nj Gov says most power to be restored by friday.

Hi, thanks for your review Philipma

But, litle problem, i have take voltage control with sucess, ok, but the firmware want monitoring hashrate, is hashrate is under 90% than target, this firmware want set more power (voltage), but the problem, is rebooting all hashboard (no rebooting miner), and my mod RE set custom voltage, is possible for you to confirm this on your kernel log , is the reason why you have "drop" hash on your average, and rejected share (rejected at restart hashboard) ...

1680mv is high downvoltage ... for resolve this problem, i want you set more, for exemple, 1690mv, if your hashrate, after arround 10min, is under target (on kernel log), please set more, and so on.

By this methode, you avoid the restart all hashboard, the firmware don't want rebooting, give more average (rebooting fact drop average), and lower rejected .

while waiting for my new version for by pass this, and make FULL fixed mod

Okay here is what I did I made a new account on viabtc

the miners.

new t17e

old t17e

just did it it will show results of the two miners at the pool
These are on our optimum backup/isolation/testing router
200mbs service
cisco 1gig switch

I will post back daily this is 2 mods on new

1680mv
90% fan on new

1760mv
100% fan on old

this is early so ignore hash difference



this is early hw errors are zero
rejects are off 7 to 1. will need to keep an eye on this
note fan speed is lower.

Glad this worked on your T17e just like it did on favebook's S17e, the results so far are based on a short period of time, i would love to see overnight temps,hashrate and pool results.

bump and a delete

here is  update we will be testing this again very soon maybe in 1 hour

after testing we have achieved

a partial success . the voltage is unlocked.

we lowered voltage to 1680mv temps are better.



Needs to run overnight, but it was doing around 1750 to 1800mv  on older bitmain firmware and ran hot now does 1680 mv.

We will work on frequency control tomorrow

here is the stock miner note voltage 1760mv

so 80mv volt savings

Agreed, this price range looks reasonable at least to the buyer side, we don't know how much work thierry4wd has put into this but we know there aren't many people who own these S17e/T17e gears, so chances are he isn't going to sell many copies, but it's a good start since he has been working on these firmware for years now and hasn't made a penny, this is a good chance for him to be evaluated and get enough reviews so that people will trust his work in the future.

Since the thread with my review is locked and I can no longer post or edit there, here are some new pictures (miner status, updated configuration page and some random snapshots of slushpool's worker page) after miner working for almost 48h:

we will work more with the t17e

I have come up with an idea that helps everyone here it is


So if we get the 2 t17e's running I will do like the idea above. Fingers crossed that we get it worked out.

Anywhere between 50$ and 100$ is reasonable imo. If I was a developer, I'd give firmware for less than 40$ only if buyer has multiple machines (5+/10+) but that is if we are talking licence based firmware. As I am not sure how OP will sell this firmware, I cannot really give a good price; will it be fee based; will it be unlimited where you can sell/share it or will it be per miner/per farm?

If it were my firmware I would probably price it at 3% of 1 year of mining, this is based on the fact that 3% is about the average fees for custom firmware, and that 1 years is the average lifetime for these lousy gears.

As of today the S17e makes about $6.48 a day, or $195 a month so that's 0.016 BTC / month so that will be 0.192BTC a year and 3% of that is 0.00576BTC or $68, can be rounded to 70$ per miner.

The price is good for the buyer if their gear manges to stay alive and protifble after 12 months, bad if it fails to reach the 12 months point, it's good for the buyer if the price of bitcoin goes up and vice versa, so it's a sort of a risk to both the buyer/seller but I believe it's reasonable on average.

I could probably come up with some good arguments on why it should be cheaper and at the same time there are plenty of arguments on why it should be more expensive, but overall I believe this is a fair price.

we did some work today. we tried getting a t17e to work.

Still needs work.

I used discord and teamviewer.

the farm has a test network of four or five units

on a verizon network. does not work.


  for security the main farm is on a second network. serviced by a different modem.

i do this with  all new gear.

we will do a new test later on.

@ thierry4wd  i will leave the firmware on it.

let me know when you want access via teamviewer.

Big oooof, 500$ might be a over the top, maybe it's good if you want to sell it to resellers, but it's bad for small miners like me or someone who has only a few of S17e (which can be bought for roughly 900$ nowadays so you get my point).

Chipless has made some kind of licence based firmware where you need to type in correct licence in miner configuration so the miner can start working (not really sure if they are calling home or he has implemented a list of 1000x licences or more in every firmware and you just need to guess one or he gives it to you, but since it's rather a lot of characters, it will probably be impossible to guess). It's per miner so you cannot share it or if you do, you might be screwed. Similar thing could be done here.

thierry4wd could ask chipless for assistance but not sure if he will help.


Not sure he has a channel yet, we used discord and discussed everything via PMs, just add djay#4807 as friend and pm him.

Fantastic work I know a lot of miners will be very happy to see this keep up the great work!

Tried to find you on Discord but was unable to find you what is your channel invite link?

AFAIK when I was talking with him about it earlier he though $500 for unlimited use was a rough figure.

Again, no idea how he would enforce that without miners calling home, not sure how the others do it, cant think that they would have the resources for that much of a foolproof DRM process, which is probably why they have the self-mining to get their fee.

That is the first thing I asked him as well once he finished the firmware. He could do something like chipless - licence based?


He hasn't yet decided on price tag afaik. Since he is the only one who has working S17e (AFAIK) he could put a li'l bit higher price tag (not that I want that since I will probably be buying future firmware from him too...) but let's hope he comes up with number somewhere in middle where it's affordable but not free.

First of all allow me to congratulate on your new firmware, I have a few questions regarding how are you planning to distribute the firmware, in other words how do you ensure that other people won't re-sell it, I understand that trusted people of the community like your first client Favebook won't be doing that, but what about others?

Also the price tag should be discussed in public IMO, pricing is very difficulty and it's almost impossible to get the perfect number that would work well for you and the clients, so perhabs a community discussion on the subject will be very helpful, of course you could ignore my suggestion and keep the sales private, I just  think it would sell out a lot better when price is known and the community "agrees" to it.

S9k/S9Se ?  

Yes, indeed it is true, I have given access to thierry4wd so he can finish developing firmware for S17e. It works as it should, in my case I was interested in underclocking due to ridiculous hot days that we have during the summer (and that we will have over next years - thank you very much global warming).

I will not be posting too long review here as I have already written a full one which you can check at bottom of my post.

This is the first S17e firmware that is legit and that I am aware of on this forum and in general. I am happy to see that people are taking after some other firmware creators and accepting one-time payment as method of selling their firmware (I do not personally like firmwares with fee since I use my machines for long time and that costs much more than if it was one-time payment).

However, as I am not currently aware of the price I cannot say if it is worth it or not, but I think he will not overprice it like some people do.

I cannot vouch that there is no malware or backdoor built-in but I highly doubt that there is one as mikeywith and Biffa vouched for this person (check the thread below for that too).

As of writing this post, my miner has been working around 48h non-stop (even though we just hit 43 C today in my city) while underclocked (whereas before I (or rather "he") installed his firmware on my machine, I couldn't run it at all due to outside temperature and machine always reaching 90 C and turning it self off or dropping to 0TH/s to protect itself).

Before upgrading to this firmware you will have to sd-card flash MPTest firmware like many other firmware since Bitmain locked most of their newer devices and does not allow you to flash just any firmware whenever you want. But I assume that he would send you a tutorial or explain you what you have to do when you buy the firmware.

His English is not the best as you can see but he is trying his best and really cares about machines and customers (or at least that is what I gathered from talking for almost a week with him).

I sincerely hope he will become one of big custom firmware developers as we URGENTLY need competition in these waters.

Oh... I said it won't be a long post.. Ah well, I tried my best to make it short.

Contains no malware of course, it is original firmware but patched

Thank you for your trust.
