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 can confirm that with my saturn but not with my jup. the jup is slower without a big fan.

2 cores is practically nothing. That shouldnt cause significant performance issues. That's 1% of cores not working on a die, or a couple of GH/s
but this one is performing 25% worse than normal one Good One shares 7630336 (99.78%) This Bad One shares 6264832 (99.64%) How to find out where the problem is ?

In your post in the other thread you posted more data which showed a >17% HW error rate, which accounts for a lot of the under-performance. By contrast, my Saturn has well under 2% HW errors. I also noticed that ASIC board #3 is getting a lot hotter than the others - ~74C vs ~54C on the others. That might be where your problem lies.

I've tried the same, but when the chips went up to 50C I've lost 20Ghs. So now I try to cool as much as I can... It gives between 550-560. 560 if I can cool down enough. So what the heck? Oh yes, the top of the box is on....

Find out at what page users started reporting reception of miners and what they did that was or was not successful at improving performance. (chuckles) I'd suggest shutting down, then putting light pressure on the tops of the VRMs one at a time. Don't expect to put enough pressure to get a snap sound. Then boot and install firmware 0.90, run enablecores.bin, shutdown, wait 30 seconds, startup. Open a new browser, go to your webpage address, sign in, hit check status, wait a few seconds, give it a control+F5, the browser refreshes, at this point sometimes it will only show 2 or 3 cores. Close IE, open a new instance of IE, repeat the process, you should now see all cores and at what percentage they're running. If there's an improvement you can move up in firmware versions or stay with 0.90. Anything over 0.94 will use less energy. Then decide if the increased power usage warrants the additional GH/s and go with the firmware you feel is best. going back to 0.90, running enablecores.bin,

I was getting >50% HW errors with firmwares over 0.94. Moving down and enabling cores, using the higher voltage I get 4.5% (my maht hw*100/accepted).

How fast will KFCMiner do RMA?
However long it takes to ship to them + 1 day of testing + shipping back. Realistically, it's around 4-5 days.

Crap, everyone is reporting their chips running in the 45 degree range. I have one at 48, two at 55 and one at 64. I'm hashing at a pretty stable rate of around 540-550. Should I be concerned about the temps?
No, mines the same. People are chasing ghosts around here.

I can't get in touch with KNC.. have left messages on their voicemail. Nothing. I have been able to hash for 4 days with a day 1 order that showed up on day 4.

Firmware 0.97 is better than 0.96 which is better than 0.95 and so on. Good job KnC!
Hmm i praised the 0.97 firmware, but now i have to change my statement. For me the 0.97 firmware had better speed in cgminer, but in the pool i had lower speed. Changed it back cu 0.96 and now in the pool i get close results as in cgminer. So be sure to check both.

Torx #15 (IIRC) + philips #1 and then the heatsink comes right off the chip. Send in the entire chip/board w/o the heatsink in a static bag if you have one.
