How fast will KFCMiner do RMA?

[eurgbp2011]

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 ?

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,

well then I'll try your idea ....
Back to the Bunker!

seems like you box has same 20% HW error rate as my saturn....it is firmware related i believe, then again, i don't know diddly.

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.

you unscrew & peel off fan from CPU and send board?

somebody doesn't like me helping competition - i post and pool stops responding, distributed denial of service attack?

Slush? Yes, my Jupiter just switched to my backup pool

Good luck with that.  I am a day 1 order 454 with a unit I can't use.  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.

Yep. 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.

i ended up doing a factory reset of a miner...got everything programmed back in, but cgminer says config file failed to load....bad option?
nevermind...I just got it going
no I didnt....said hashing at 18gh/s with bad credentials, when I know they are right

So who else is having this problem with jupiter?

Seems a ton of miners are running at almost half speed, issues with VRMs 0A:

do you need to run enablecores.bin on .97, not sure? Anyone?

[cognoscente]

do you need to run enablecores.bin on .97, not sure? Anyone?

If it doesn't work out, here's how to roll back per KNC:

For those that experience degradation with 0.97 we recommend the following steps until improved firmware is available:
 
Revert to firmware 0.95, 
Make a hard reset (see manual)
Ensure poolsettings are correct.
Apply patch “enableallcores” found on the support page.
Restart CGMiner
 
Please also check the following:
Pool address and ports correct in mining settings
Miners have a high quality internet connection that does not cut off.
 
Test the miner

do you need to run enablecores.bin on .97, not sure? Anyone?

as long as you have already run enablecore.bin at least once and/or flashed 0.96 at least once you should not need to run it.

/etc/init.d/cgminer.sh before starting cgminer go through all the cores and enable them.

I don't rember where (and I don't have time know to look up for the post, pardom me if you can) but I read that one of the first fw (0.90 maybe) wrote the map of bad core on asic eprom and there was no way to overwrite it at runtime. that's the reason why knc release enablecore.bin.

My plug'n'pray device is on it's way

Do we get pictures and a cake when it arrives?

[jelin1984]

how i can add manyally at cgminer at knc

restart the device when the hashing speed at pool is low!!!!!!!!!!!!!!!!!!!!!!!

any details?
