primecoind %CPU between 700-800
what mean this?

Sounds like the miner is properly using the CPUs at least, that number means 90-100% usage across all 8 cpus. I think recompiling with the latest libgmp is your best route.

I'd hazard a guess that it's not properly threading the CPUs, as you get similar pps as my i7-920 @ stock. AKA it's running your 8 4 core CPUs as 1 8 core cpu.

huh
i have too 920 on desktop pc, i'm doing with it around 3300....

Open up your makefile, and add -O3 -march=native -s and recompile it from source.

Also, do that with libgmp for even more performance.

DON'T do that with GMP. GMP is already tuned for greatest performance, and using "-O3" can sometimes break code.

Maybe i will try it, just to know if are any differnece.
Like I said I'm using libgmp3. Should run like libgmp?
