Topic: Swedish ASIC miner company kncminer.com - page 60. (Read 3049514 times)

I've always run all of my dies at 325mhz since it became an option. I run some at - 0.0366, and some at lower or higher voltages if needed to maintain stability.

Why do you ask?

Er....been running all my cubes at 325 for months now (except for 2 that were set to OFF the first month and recently had 2 dies (on cool cube not hot die ones) set down from 325 to 250 and 275mh receptively (summer may try to up them again now that winter in my bsmt) (my setup lostgonzo.imgur.com)


Perhaps you meant 350mh setting mod instead of the 325mh above? 325mh setting on the adv page is quite common. At least that was recommended as 'suddenly' ok on the 2nd or 3rd firmware version ...when I an others reported bad die issues (and thus the 'new' policy if set at 325 on adv page all cubes and you can get over 300mh KNC does not have to RMA squat.)

oh my titan(s) are both NOV 2013 units. My orig Titan's warranty (such as it is) will run out Nov 6th I think it is. Soon to doorstop afterwards I'd guess

(re-read the above you must have meant 350mh settings mod on adv page?)

POLL: Anyone here actually run their a cube at 325mhz @ -.0366v setting and it has no issues doing so?

Also, anyone run dies above -.0366v? (lower number).

 Below is the now ENGLISH version of the previous Swedish Language version of the Titan Cube You Tube Tear down mod:

 https://www.youtube.com/watch?v=-G_zcJ0vbOw

 Here again below is the original previously posted SWEDISH language version for reference (shows better on the paste application on ASIC chip)

 https://www.youtube.com/watch?v=O-RBI4am-wY

 NOTE: A previous poster in reply to the above Swedish video said that too much paste was used in his view. In the English version of this you tube tear down video
 he addresses this by saying due to the heat sink pipes and 'irregular surface' MORE paste is needed. I have no idea. Just pointing it out for the more informed
 of us here to consider and/or post about.

 The others have also posted that their are ways to 'line up' the heat sink and the ASIC chip. He says in the English version there may not be. Again just pointing
 it out so others who have done this mod or know more can comment thru a post on this here for help.

 Looks rather 'daunting' to a newb like me. Main concern would be if there is a correct method or 'pin' to line the ASIC up and/or how much paste to use. Stuff like that.
 
 On the other hand in about 2 weeks both my Titan units (new one bought and the one bought used in march) will be off warranty. The 12 months will be up.

 So likely I should consider doing this on at least one cube, if for no other reason to blow them out with air and likely after 1 year of 24/7 the paste probably DOES
 need to be replaced badly due to the ASIC chip paste being dried out.

 Titans always a 'heart in throat' moment either thru stuff like this you should do or by them suddenly bricking themselves into door stop mode for no particular reason
 and you scramble to get them back up and the hamsters going on the treadmill again

 Anyway hope it helps.  Comment here for improvements/corrections etc those who know more then myself. I'd also look at my previous post on this (SWEDISH video)
 when it was the only one available ..for comments and/or improvements posted there after. That also is on this thread farther back.

 Enjoy

 

OFFICIAL ANNOUNCEMENT!!! v.99e is ready for download!!!

Changelog:

If ur still a free member, well all the more reason to upgrade =)

If you have my btsync share, the new version will be available once it sync to ur client.

Thanks all for ur continued support & funds & donations!! This firmware is turning out to be quite the gem!

Future releases:
The "Energy Saver Edition" - autotunes voltages per die to as low as possible while maintaining decent hw% & die stability.
*possible tweaks: pool info added to status page.

Sweet, thanks will keep it in mind. The code Im starting on now is gonna need lots of testing before its perfected. Its the autotune functionality. To be branded as the "Energy Saver Edition" =) .... or something like that.... LOL!

Looking forward to it. If you need an extra beta tester for future releases, feel free to PM me.

v.99e announcement coming later today!!!!!! =)

A guy in one of the videos mentioned an Ideal liquid for submersive cooling that was like 200$/gal. Had better thermal transfer qualities than mineral oil, and was inert. Mineral oil is pretty cheap if you get it in 5 gal pail. The whole thing is probably pretty cheap. For me the real problem is it's so messy, like if you have to pull the cube out to work on it. But Y connectors probably last forever. I also think it's interesting how they run the fans "underwater", no problem.

It's still in the back of my mind

The sad thing is if I had the time, I'd contact the EE dept and Mech Engineering dept and they could whip out such a water block etc for giggles...but don't have the time
to chase them down with pizza and beer (ie local mech engineering club and or ee club etc) God knows they have all the mnfg ability there to make a clone Titan imho!
(no really I think they have those 3D printers for circuit board thingys.. so we just have to get KNC to open source the Titans/Neptunes .right (lol fat frigging chance)

Anyway side note...if you do have a shot cube say wandering by your local university EE dept and finding the EE club.(if you have a local university) ..
...you might just be able to revive such a cube or issue on their good graces.

....if they think it is a 'cool' little project...but again ..like all hacks 'pizza and beer' would be required ...so I keep this in mind as my Titans pine for the sweet release
of becoming 'door stops"......it shall come...and if I look desperate enough I may have a shot...cubes in hand wandering the EE dept despondent

anyway others in this thread with equipment... in a univ town with the above options may want to keep this in mind

(On the other hand a few years ago i got an apple //e from the 80's/90's that used to run an electron microscope for 'dapple' imaging..looks nothing like an apple //e
..It has all the books and stuff needed to fire it up ..it sits there waiting for the video/monitor feed once it boots looking for the electron microscope lol
...I asked the physics dept at the local univ if  they wanted to try that on their electron microscope for kicks....i got a resounding NO!
...go figure?)

On the other hand you look on ebay you sometimes see stuff like 'Electron Microscope' not currently working all manuals etc. for like 500 bucks or less. The status
is 'pick up" with lines like 'your expense to remove the wall and permits and use of the crane..etc) is a hoot! All stuff becomes doorstops it seems.

Anyway I was just asking if anyone HAD water cooled a Titan or Neptune maybe ..expense be damned....people do silly stuff like that ..so worth a shot



Ah...did not see this previous post....I could 'hatch' a plan and drag the now defunct for making btc (but works fine) KNC Juptier to the local univ EE club etc and show
them this..they probably have the liquid stuff laying about...(er not mineral oil there is another fluid from other videos if I remember right now that you have jog'd my memory to 2013 using I think a 3m product?.....I know such exists ..probably causes cancer by reading the label....but they could have fun with such an experiment.not like I'd worry about them 'breaking' the knc jupiter as a 'lost' miner due to difficulty vs electricity now. Then if it worked..you could 'hatch' the evil Titan plot below (evil laugh here brhahahahaha)

Whet their appetite .....assuming we got it to work on a Jupiter Die....then I could continue my evil plan and off hand say...by the by I have a current miner...Titan
perhaps we should use this as a real world test make a video.....(ah evil plans have to love it)

Might not work..they likely would just call security ..but still......the real trick would be using 'univ elec' and forgetting to mention its mining to my address (naw ...I'm
not KNC ..a slippery slope what?...) Gee guys that looks cool you should just put the whole works in this 'display case' over here and we can see how long it runs...whatcha say?

(I am beginning to sense now how KNC got taken over by the 'dark side of the asic force" The 'dark side' is 'seductive and strong' dont' ya know

Hrm.... I dont know where that bug came from, the code for that is pretty simple. It sounds to me like maybe the firs time it just failed to save the preference to the file for w/e reason =/ ... so far noone else has reported this issue.

I can try to add that to a future release for the pool info readout on status page.

I just started using .99e

BUG?: I had to specify ENGLISH for the language more than once.

Feature request:  Since multiple pools can be specified, it would be great if the Status page showed you what pool (or pools) your miner is connected to.  Obviously this has always been a problem since KNC's original firmware.

99e, so far, so good.

Dont let that secret out!!! LOL jk =P yeah I switched to it a week ago, the titan absolutely loves it. Best pool ever!

Thanks to KNC miner I got both of my controller boards working again, damn EVGA power supply literally smoked my boards, not knowing the cause of the issue I sent both controller boards back to KNC they repaired them sent them back and poof the damn power supply smoked my raspberry pi. This time I used a new power supply and luckily it only smoked the raspberry pi this time and I needed to reflash the card with gentarkin 99d and I was back in business.

Cant wait for the new 99E.

BTW Is everyone here on Prohashing.com ? Seems to be the best pool I have found for SCRYPT mining.... thoughts?

Very nice =) , yeah my titan is a bit picky, I have one die that has like a 2% rate no matter what voltage, I imagine there are others out there w/ the same situation, so those dies will be hard to account for. Ill have to code in something where if it keeps raising voltage w/ little hw% change then it will just revert the voltage to where it was... somehow lol

New firmware may make it out today, or tomorrow. Im awaiting test installs on someone elses titan. If anyone wants to volunteer shoot me an info. For those who have my btsync share , the release is already in there. Test as you please and let me know. Its so far, appeared to install fine on my titan, although since its my dev environment, its a bit different then everyone elses =P

Looking forward to the update!

In regards to auto-tune, that's a good idea. I've done the tuning myself manually, also aiming to have no more than 1% HW errors per die. Once that's dialed in, I leave putty connected in screen to monitor for bfgminer restarts due to dies being un-restartable with your watchdog. When that happens, I bump the offending die's voltage a notch until it's completely stable. That leaves me with a 100% stable Titan at the lowest power consumption possible.

Here's what that looks like:



That's mining on nicehash in case you're wondering.

UPDATE: will be releasing v.99e within a couple days, maybe even today =P

Features will include:
-groundwork code for multilanguage capability in webgui. Upon reboot after installing upgrade it will ask which language you want the webgui, only working & complete one is English for now
-chinese skeleton site, only includes the status page translated
-much more accurate wall watts
-ability to set your PSU's expected effeciency in SYSTEM tab which is used to calculate wall watts(defaults to 85%)
-more accurate cube power consumption in ADVANCED tab
-more modular code in monitoring script(which will give way to autotune someday =-) )



Future release:
Since I have the code in place to deal w/ the config file for voltage & clocks now, I will start coding some sort of autotune sometime =)
Im thinking initially it will only adjust voltages up and down a few notches by monitoring HW% error rate for each die in bfgminer and adjust voltage up/down accordingly. The maximum hw% Im gonna let a die have is 1% (overall hw% no greater than 2%) (based on my titan) .. Im not sure about the overall range of die hw% quality out there so a lot of this will require people willing to test the autotune.
Best(desired) clocks will still be required to be set by user.
There are lots of stuff to consider when tinkering w/ voltages automatically, such as per die DCDC current draw, per die DCDC temps, overall cube power draw, HW%, etc... this could get really complex really fast which is why Ive been putting it off =-P

here you go searing   --   mineral oil cooled mining rig

https://www.youtube.com/watch?v=EpNERMxvPTk&feature=player_embedded

this actually might be feasible

-- run main supply & return tubing to an automotive radiator
-- put a larger circulator pump in the main loop to keep the oil moving
-- use a smaller pump for each cooling tank that taps into the main supply & return
-- set the PSU's above the tank on a rack
-- move the radiator outdoor in summer & indoor in winter

other videos show the psu in the mineral oil too, but that'd take a lot more work and  larger tanks.

I wonder how many cubes one radiator could handle?

Dumping that sorta $ & time into a project like water cooling titans .. is rather pointless and a waste lol!
Would have to make a custom block just for the dang VRM's and the ASIC. I dont even know if the ASIC runs that hot.
It consumes about 250w overclocked, highend video cards consume that much and have smaller heatsinks and are cooled just fine.

It would be nice to know the actual die temps of these things....guess we'll never find out LOL

Hey I had a thought...has anyone been crazy enough to 'water cool' these Titans or Neptunes...that would be cool (and likely expensive) but man that would be
a cool youtube video

(I nominate TXSteve (Titan) and Telsaman..(Neptune)...  all those in favor...carries....hop right on that will you my good fellows..thanks )



my titan has all them temps beat ...at least this last summer.....the orig 2 dies on 2 cubes that I have OFF have been so since last winter. So the likely
too hot the way I ran them ..did not seem to (yet) have an effect.  Basement setup. lostgonzo.imgur.com Just using fans an airflow thru Basement.

Then again my Titans the orig and even the 2nd one probably (newbie on temp beg of summer) been run way to hot under what you know recommend. Kinda
glad I did not know this over the summer would have been freaking out. I thought 90c and below was OK.

The 2nd unit I got from a guy in Australia was run even harder before I even got it. Winter here is Summer there.

 The way I can tell from his cubes from my cubes is from the way the paint is flaking off the top....
...got that faded "sun blasted"  look....I'm sure it will bite me in the a*ss soon (short life) but whatever been lucky

whatever this is likely my last season of home mining anything ..this winter... anyway if it can hold together and beat elec price thru that season vs coin its a win imho!


Sigh ..I always thought this crypto mining hobby I got into in 2013 would have been a LOT funner with 4 guys and a co-op kinda arrangement..how i used to run a huge gamer BBS...4x the cash. 4x the equip 4x the size..and.someone always available when one of the sysop's cracked up and made a mad dash to throw the dos server off the roof. (ah good times drunk computer builds)

So I would be up to doing a lot of these mods and stuff..but away from the crypto mod herd ..all by my lonesome....little time...and the cowardice of being alone.

Well probably for the best a co-op of 4 buys in 2013 we would probably have been 'taken' by BFL and I'd have 4 less friends..but this stuff would be a hell of a lot more fun
with some more folk. (I've tried ....in upper midwest USA from what I can fathom ..if you do bitcoin..you are more 'evil' then a door to door Amway salesman)

But doing computer mods in my past was always with someone along the lines of 'are you sure you want to do this''wtf did we do wrong i can't get it back together'...and of course the classic ' well that did not work well at all..... we needed a new (? put device here) anyway I guess...er hand me another beer (we used that a lot)

Its not the KNC junk that bugs me on these projects..its the lack of the cooperative effort of others to get around such..ie locally here with the shared crypto viewpoint......so far out in the crypto sticks I am!
