Hello, haven´t had time to go thru the Newbie process before but as it just has changed I thought I might do some good here.

We are running a large amount of KNC Jupiter Miners and has resolved most problems during these first weeks and we have a large understanding for why issues are present on some miners.

Lets see once this newbi status is gone I will post some in the KNCMiner thread that might help some people out (or at least give them some clues whats going on).

Cheers

Thanks for offering the help, I really appreciate it!

I have a Mercury that's doing good, hashing at ~145 GH/s, but my Jupiter is a complete disaster:

I received my Jupiter today.

I tried all firmwares, always with enablecores and the only one that seemed to be hashing at some (relatively low) rate was .95

.96-.97 were a complete disaster with the miner regularly starting high at around 150 GH and then going down to zero, always accompanied with errors like

[2000-01-01 00:34:22] KnC: accepted by FPGA 14 works, but only 0 submitted

flooding in en masse when running "screen -dr" on the ssh console.

On .95 I'm hashing somewhere around 300-350.

I'm still seeing the error message above on a repetitive basis, but not as much as on the other firmware versions.

I'm also seeing this error from time to time:

[2000-01-01 00:03:38] KnC: core 2-76 was disabled due to 10 HW errors in a row

I'm seeing via bertmod.bin that all but 3 cores are off, but I'm also seeing that one of them is a bit cooler than the other three (see screenshots).

My question to KNC: What do I need to do to get it up to the advertised 550 GH/s level?

Here's a snapshot of the screen -dr output:

And here comes the worst part, my stats as reported on btcguild for the jupiter indicate:

Est. Speed: 251.22 GH/s
Accepted shares: 622592 (25.25%)

25% accepted shares? Does that mean I'm basically hashing at 60 GH/s's worth of hashing power?

I also posted some screenshots of bertmod here:
