Topic: New Project. A 1 board s19 110 pro. Make it a s19xp Some photos to follow (Read 675 times)

anyway, S19pro 110T is wind cooling, it is stable than S19XP water cooling..... 

I have to play a bit more to perfect these.

I love the look of the red chimney model but it needs a ½ inch offset to cool correctly.

The 3d printer I have access to is just a bit too small to correctly build the newer case.

I do have an idea to offset the fans that should work.

I did run it using a single hashboard by disabling the other two before building the box. I may disable one or two hashboards if i need it to be even quieter later. Yes it was tested at defaults (louder) but has mostly run at the min setting of 1677W because its even quieter. The input ac is actually about 204V (would be 208V nominal in theory), whats what you get when you have 3 120V phases and use the hots from two which is what is typically given to each flat.

If you use only one board you are using about 1/3 of the power target set. So 1677/3 is about 559W + fans.

i used apw3++ and loki chip to allow the apw3++ to be accepted by the controller.

the apw3++ could use 120-240 and you could add one to to your 30amp circuit they are well under 1000 watts but you need the loki chip or the controller will not use the apw3++

Very cool - so looking at the way you've got it running, have you fitted it with a Loki Kit? (just curious). Looks like you've got it running on 240+ Voltage.

I don't know why I didn't think to fire them up without it.... I bought a couple pre-fabbed units from Altair but also built 3 of my own. I have them all doing their thing in garages/basements lol.

Just thinking though.... when I built out the electrical in my farm, I ran a bunch of 100% Duty Rated L6-30R receptacles to 35A Phase Combining breakers with 8 AWG wiring going from the panel to the receptacles.

Most of my PDU meters will show a constant draw of about 5.2-5.6 kW (with a total *peak* capacity of 7.2). Could totally fill out some of the available headroom with more setups like these where that would be safe but running an additional whole-miner setup would not. As we near the warmer months - the garage chimneys will, more than likely, have to be powered down or relocated... Maybe this is my solution.

And you are running a full unit  at 3000 watts or 2600 watts or 2200 watts.

using 230 volts correct?


It is not relevant to this thread as this is about running under 1000 watts and 110/120 volts.

I realize I can make a different enclosure but I really am aiming for under 1000 watts with a psu that can run at 120 volts.

I did a braiins model in the 1 board case and it is good fairly quite and fairly efficient.


I really wanted to perfect a 1 board design. Under 1000 watts

I tried putting a miner like that (vertically on top of some grill like yours) at home and the result was poor, very noisy and not stellar cooling. So i built the DIY "black box" of mdf and put it inside, this lowered the noise to about 50db, but the most impressive change was the cooling, the fans spun down much more to keep it at the target, since i put a proper heatwall (made of the same MDF as the rest of the box) that only fits the two main miner FANS. The improvement in cooling was astounding.

Leaving the miner like that vertically on top of a grill with the rest open, was big no no, noisy and overheated.
Also, Power Target is more efficient than Hashrate Target in Braiins OS. Indeed mine is set to Power Target and the lowest setting. Before the box i had to disable a couple of hashboards to make it quiet, not anymore...


(top cover removed)

I was busy for the Easter Holiday. On monday I will figure out shipping and how to price it.

I am interested in buying one. But the duties are 36% here. There might be a way. Advertise it as a smart hearter

Like this
https://heatbit.com/products/heatbit-mini-pro

that would be interesting to build but costly.

a look into a 1 hashboard hydro model would be nice, s19 or new s21

basically for a 120 volt bitcoin   miner in the 390-850 watt range

this is pretty much the best one I know of.

You could actually make a profit by simply just mining on a normal pool.

I love the Apollo
I love the usb sticks
I have a Avalon nano on the way
The bitaxe  is cool but this is simply better.

Given time I may figure a better psu allowing it to go to 40-50th

Still playing with ideas.
the psu below will go to 14.4 volts but is only able to do 960 watts

https://files.trcelectronics.com/datasheets/lmf1000.pdf?_gl=1*1ngnflo*_gcl_au*MTE1NTU1MTkxNS4xNzExNzQ5MjE0*_ga*MTIxMTU5NDc1Mi4xNzExNzQ5MjE0*_ga_EPGFNBGWMN*MTcxMTc0OTIxNC4xLjEuMTcxMTc1MDE1OC4yMi4wLjEzMTgxODYxOQ..

the one below is too long 250mm

https://www.mornsun-power.com/html/pdf/LMF1500-20B12.html


it would be perfect if it were about 225mm

I found a way to do lower settings I can now go to 392 watts on my k-watt meter

392 watts doing 17.56 th = 22.3 watts a th.

it can go lower but I am pretty happy with these numbers.

without a doubt the epic controller and the psu/loki chip spoof make a good piece of gear.

392 watts to 800 watts
17.56 th to 33th

basically if you manually set epic controller at

freq 275mhz
volts 12.4         does not matter as the apw3++ is always set to 12.5 volts
fan    30%

you get 26.6th and 561 watts which is 2x the s9 th and 1/2 the s9 power

4x as efficient  as  that of an s9 .

at 22 or 21 watts a th and fairly quiet not perfect quiet.

the epic controller will not let me set to 20% on fans which would work .

The red model is set to go and is a very good piece of gear. note the white grill is needed with the 38mm fans on the bottom




settings for my current screen



the watts are far lower  562 on the kwatt meter



see meter below

Sure the red one has an epic controller

it can do 20th to 30th as is but if you want it to be faster I can swap out lower fans and add a grill it would let you do as high as 35th .

I can have it ready to ship by monday.

the green one is ready today it does 32 to 37 th.

these use only eth cables.
the apw3+ psu can run on 120 or 240
it can only do 12.7 volts which is why you are limited to 34-37th on top end.

I left out the wifi mod
I left out the more complex psu mod. lowers costs.

Not sure what to ask dm me and we can talk price.

I just boosted the red epic to 30 th see below gui




new white grill shelf for better air




close shot of red epic controller  version note I have 25mm fans on bottom I am replacing with 38mm which will allow you to go to 35-37th


close up on the green one.

this is the braiins controller.

it drops to 32th and up to 37th  has 4   38mm fans

It would be cheaper






If you talk parts

Epic                                                  Braiins

new controller            =   150                             110
Oem full red case       =   200    green knock off     40
chip to trick controller =    35                                35
1 s19 xp hash board   = 1000                            1000
white grill  shelf          =    15                                15
used apw3+               =    30                                30

parts costs                 = 1430                             1230

labor  maybe 1 hour a unit
design time to save on costs maybe a day or two.




I am not going to do a full mod on the apw3+ psu's costly time consuming and since these will do 35-37th and 900 watts on top end that is enough.

the epic will get 4x 38mm fans in a day or 2      it will range from 20th to 35 or 37th

the braiins is ready and is more basic  it ranges from 32th to 37th

both allow fan control and when all four 38mm fans are at 3000 rpm they cool okay at top speed of 35-37th


I am hoping to get to some cheaper gear like a basic s19 but that will likely be in May.

I have a third piece it is red with epic and is the more deluxe model.



The hashboards are from October 2023
all fans new
controls boards new
the apw3+ psu's are 3-4 years old they had two mods one is to go to 12.7 volts the other is to the cables so they fit to the s19 xp hash board.

If I make a lot it would be maybe a total of 60 of them.

9 with xps'
6 with s19 pro  110
6 with s19j pro 105
rest with various s19s

Any ETA for purchasing?

lowest setting is 60th for three boards which is divided by 3  to get the one board i used so 20th on epic controller is as low as you can do.

20th is around 525 watts

highest option is on braiins you can do 37th which is around 900 watts.

both machines are temperature dependent colder means better efficiency. I can get them to do 22 watts a th in a cold room.

these are eth based only rj45 plug in.

please do a 400 watts option like apollo 2 miner, bitaxe miners. Please also have a RJ45 port. Hoping your project suceeds.
Tie up with D-central for shipping

two units one with braiins does 32-37th

one with epice does 20-34th

the case in red is Oem seller the green one is my buddy doing a reprint.

the case has a pair of design flaws.

so in my green rebuild I raised the case allowing a set of 120mm x 38 mm fans.

both are running on the same 120 volt 20 amp circuit pulling about 1400 watts total

so you get over 50th at under 1400 watts.

fan speed on the brains all about 3000 rpm all fans are 120mmx38mm Two fan sizes on the epic in the red case the bottom fans are 120x25mm

---

---

note the gray Oem grill it is short and does not allow for unrestricted airflow if you put a 38mm fan I used a 25mm fan on the bottom so the red unit does not cool as well as the green one.  also note I have a 12 inch board under the 2 units along with four white rubber feet to anchor my modded  version


you can see the 25mm fan is tight. you could put this red model with the gray bottom and 38mm fans if you set it on a grill like I did with the green one.

fancy duct restricts air I removed it as it should have flaired outwards not inwards


duct is fitted loosely to show it restricts air flow

braiins only goes down to about 32th

epic has more range 20 th on the low side 36th on the high side.

i am using noctua 3000 rpm industrial fans they are not good enough. which i suspected would be true.

I ordered some delta they do 3700 rpm and 151cfm i have used them on other quiet builds.

If I set them to 3000 rpm they are quieter than the noctua at 2800 rpm

I skipped a few things to save money.

no wifi saves money.

these are good units i prefer the epic controller over the brains controller.

it would let me do 20th min up to 40 th max maybe more.


here is the gui at 30th fans at 94% which are too loud note that it reads 736-737 watts. it is lower on my meter 716.9 to be exact

note chip temps are 68.9 c







now I have perpetual tuning set to 90th which gives 1 board 30th.

I am going to set it to 105th which is 1 board at 35th

I will post back in an hour.

so 35 th
868.9watts
830 watts my meter.

note temps crept up to 73.8 c

these noctua are at 94%

so they will not cool a 40th setting well they are good at 20th  to 35th

Happy to see you making progress here! Curious... which model Noctua fans did you use? and would you say it is quiet enough to run in, lets say - a living room?

I noticed the same as you regarding lower clocks on the UMC vs BRAIINS. Using BRAIINS, setting the frequency under 368 MHz on my single board 19K miner results in failure to start hashing at all - works like a charm, however, using PowerPlay on the UMC.

Excited to see what sort of a case design you wind up with!

won't fit in the case. that is built for this mod.  Also the apw3++ is around 90% efficient.

I just about have the build done.

I ended up using an epic controller.  the epic can go really low  board can do 23th instead of 30th


decent stats and fairly quiet.

I can down clock more and I can get it quieter
I have noctua fans set to 2500 rpm

what can be said about the efficiency of the old/new bitmain PSUs?

Would it be better to get a PC PSU with a high efficiency platinum rating?

Might only be 5% difference but that might add up over say 1-4 years

175.2 is saved over 4 years at 1kw and price of 0.1 kw/h

I talked with Altair tech.  I may make 10 or 12 units.

a s19
a s19 pro 110

a s19 xp


that comes to 9 units.

I will need the Loki duo and I will use braiins

I have a guy that can print cases.

I have many apw3++ psu's


If you look below you can see  an xp is says 791 watts, but it is more like 740 watts.











other than the Loki kits and some new extra controllers

I have 60-70 s19 boards

If you do the lessor psu mod. the psu's do 12.5-12.7 volts

this lets you go to 800 watts easy.

I have 2 loki duo kits on order.

once they arrive I will build an xp in the chimney

and have my buddy print a case for the 100th pro.

 I think build this and liquidation go my btc asic miners will be my 2024 move.

I know someone who did this very thing but ended swapping the small fans with a duct fan, 4" or 6" AC Infinity.
With the njord to control the fan and loki to use a modded S9 psu...

that should definitely be achievable! I purchased a BitChimney from Altair Tech (along with 3 other 3D Printed Shells - my ender 3 pro just died, but I want to make more of them before deciding between Creality and Bambu lol).

The BitChimney, utilizing a single S19K Pro board, an APW3+, a Loki Kit from PivotolPlebTech, and a Xilinx controller with BRAIINS (or a UMC w/ Powerplay), pulls similar figures.

The screenshot linked is running on US residential power (116V measured at the wall with a Spartan meter *purchased from Amazon for about $25 - not the most accurate tool but close enough*)

Love to see more people exploring the possibilities of what can be done with low power expenditure - getting residential mining enthusiasts back online with far more impactful hashrate. Looking forward to seeing how you make out!

I decided to go with a s19 xp not an s19 110 pro.


It is hot in the garage so watts go up a lot.
811watts  is not my real power use my meter reads 750. I know the meter is good.





here is the xp with a braiins controller and 1 xp hashboard attached




here is the power meter once I opened the garage door watts dropped from 750 to 698

so the gui reads 811 watts and the meter reads 750 hot garage door closed
the gui reads 760 watts and the meter reads 698 garage door opened .

this unit Is running at the mine it uses 240 volts. and about 3200 watts at full speed.
it has standard fans and is Loud loud loud!

the mod will allow for 120 to 240 volts

it will use brains and must stay under 12.5 volts.

You can see it does 11.75 volts when set to 96 th or 32th for a board

this setup when built will not use the stock psu.
it will only use 1 board.

and depending on settings the board can do 20th to 30th at well under 30 watts a th.

it is still tuning so the numbers should get better.

So I was thinking if I could mod a mod that is offered on line.

I would run braiins+
I would tune the board to 30th and about 875 watts

I would use 4 noctua 3600 rpm ppm 120mm fans.

I Should have some posts on this soon. and of course some photos.
