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.

Thanks very much, j03. I'll try testing that way.
I have not been able to find the bash script, but I'll look again. A couple questions:
1. Is Bertmod ZPM different from v4? Is this from the KNC forums?
2. Have you done any SPI voltage, SPI frequence, or per-die tuning in the KNC Advanced gui?
3. What's your order of procedure? I have:
-flash a KNC firmware
-run enablecores.bin (just out of habit)
-let the machine spin up
-ssh into cgminer
-"vi /etc/init.d/cgminer.sh" to get to clock settings
-adjust clock settings
-type esc, then a colon, and then "wq", then enter
-machine seems to reboot on it's own, i don't restart
-watch the new hashrate
-mess with tuning, even though I don't know what im doing
-compare pool and machine hash rates
-wonder what's going on (LOL)

Could you share? Thank you very much.
