Re: Hacking The KNC Firmware: Overclocking

Any ideas on how to reduce errors? Does tuning do the trick?

I've been getting some crazy machine-side speed reporting from an October Saturn. The KNC GUI is showing 398gh. SSHing into the machine is showing 398/355.

Poolside, however, I'm apparently only getting 227? Can this be accurate?  I presume the problem is errors, but I don't know...

Just my 0.02: I noticed better hash rate matching between the pool and client with cgminer 3.9.0 on firmware 0.99.1-tune. As far as reducing errors, I've had good luck with not overclocking, or underclocking, some dies and overclocking others. Use the bash script that CYPER posted in this thread a while back in order to set per die clock settings. I still use Bertmod ZPM fix to analyze individual module/die performance.

may i ask what the Bertmod ZPM fix is? I only know bertmod 0.4 so far.

If I remember correctly its a hack someone called ZPM did to make 0.3 work with some later firmware.
