EUREKA!
I just discovered something.
They don't like to be OVERCOOLED either!

funny i was having the same thought after seeing them cooled and no real change, as well as others mentioning that they ran their unit hot on .90, that it might allow chip to seat better in solder or something like that....

what stats u got phoenix1969?
its too early to tell because it will take time for my averages to come up, but it looks to be the final tweak, like it may end up 275, 280+, 280+
im optimistic, but definitely see an increase, and within 2 mins...
all I did was shut my boxfan off
I was all proud of my 32C temps, lol...they like 55
And you now have 200+watts more at the wall for each Saturn?

I have to ask, does this look right to everyone?  I am wondering if it is a bertmod issue or why I get such poor performance, just disabled cores not showing.



I cannot see this in control panel v0.97
How to get these details???

0.97 also shows a continuous drop of hashrate for me from 500 to 470 (3 hour average eligius).




Actually.. it doesn't seem to be coming back in any previous firmware. Last value was 450 and that's where it stayed. I read compatible reports on KNC's forum. I fear 0.97 might damage bad Jupiters... Careful upgrading yours.


.96 does seem to be better than .97 on good jupiters.   I haven't tried it on a bad jupiter yet..  so far bad jupiters hash better on .94 'overclocked' running bfgminer but the VRMs/chips do have to take a beating..  perhaps heatsinks?

to 'cure' modules, remove the asic_test file and install .96, run enable cores and few times and reboot.   It should do its 1-2 min asic tests and then reboot itself.  you should have more enabled cores again



How do I remove that asic_test file??
+1

Please some help on this.  I can't seem to find the answer.

I'm not sure why you need to remove this file - I would think it would just overwrite it, but if you really want to remove it:

SSH into the machine, then:

# cd /config
# rm asic_test

The '#' is the command line prompt - don't type that.

Well, I read to try it here.  And I read about it on the knc forum.  Seems like someone wants a guinea pig.  Any success with this?  Anyone?

If you are concerned about breaking sth, just rename this file ?
Then you can revert it anytime.

#mv /config/asic_test  /config/asic_test.bak

mine is v0.97 and I don't see this file

Has anyone been able to get ahold of KNC today via the phone?

Called about an hour ago - nobody picked up and then it went to voicemail in swedish.

yea same here.

Try their Facebook page. Public questions tend to get answered fast.

let's have some fun
October 25, 2013, 09:05:07 AM
stay on 0.95 - gives me better results than 0.97
which is weird, coz flush work seems to be fixed, but hashrate is still lower than on 0.95 with flushwork issue

*ok consumes less W, but I prefer more GH/s now

Clueless!

I go with (HW*100)/A

HW error % = HW/A+R+HW

where

HW = number of hw errors
A    = number of accepted
R    = number of rejected

with 0.97 I got something like 10-11% after almost 20 hours, whereas before the same miner running with 0.95 I used to have 5-7%

Thanks.  That changes mine from ~4.4% down to ~4.1%.  Although it doesn't agree with BertMod:

Device Hardware%=4.9875
Device Rejected%=4.1048
Pool Rejected%=4.3372
Pool Stale%=0.0000


mine is with screenshot of 548.4gh at the time it ranges up to 555gh i'm on .95
Jupiter (stock no changes)  with the (HW*100)/A  4.05% and the 2nd method above of 4.27%

so don't think i'm gonna upgrade yet...to .97

by the by I think I figured out why it seems folks "destroyed boxes" on arrival pics like mine arrived ...are showing or seem to have less problems.if the damage that severe happened at the beginning of the trip..the miner was basically 'carried" in 2 hands or it would fall out of the box..ie only explanation I can think of in I had only 1 fan loose and it works so well ..so the more destroyed the box the less likely they could toss it like a Frisbee..imho (weird thou)

of course it is likely just dumb luck..not sure that is what you want to see thou the DHL guy carrying your crushed wed dripping soggy miner in box with 2 hands to your door ...I musta looked like he just ran over my cat

anyway thanks for the info on knc miner use of this info etc

Have you ran that Board in Isolation to see what Hashing rate you get from it. Unless its a mercury (if so what's your Speed).

I have to figure out which board it is first then I can get a speed on it.  Should be easy to spot though if that current stays the same. I will report back.

What are these VRM's I've seen the last 10 pages? Are these those rectangle looking metal blocks on each ASIC modules? Each with a small white piece of tape/sticker on them? According to my thermal temp my warmest one is 90F. Maybe sticking a piece of thermal tape on top would help it out, no?

Like stuff like this?


http://www.frozencpu.com/cat/l3/g8/c487/s1288/list/p1/Thermal_Interface-Thermal_Pads_Tape-Thermal_Pad_-_05mm_-Page1.html



No.  Heat travels best thru metal.  Abutting perfectly flat metal surfaces should conduct heat best but the surfaces are never perfect.  Heatsink compound or tape of a heatsink compound with high thermal conductivity is sometimes placed between the metal surfaces to fill in air gaps.  No heatsink compound or tape conducts heat as well as the metal itself.  If one were to put heatsink thermal tape on the outside of a heatsink the heatsink would become less effective at losing heat.

I tried. Nothing is loose.
How to detect which board is faulty?
I'd have to send back to KNC some boards, but I do not know which one to send.


Run Each board in Turn in Isolation for an Hour each or more.

Record the results (Hash rate, HW errors, Cores on and off and VRM DC/DC Status (using bertmod) ).
