How Many Cores?!?!?!

[Lightman]

Oh that was quick, thank you. Guess there is still some room, I assume the NB/IMC is running at <=1600MHz with 1650GHz core speed. The results look like IMC/L3 bottlenecked, can you run with DDR3 at 1066 which should roughly equal DDR2 800. Max possible for DDR3 1333 eight channel is ~85GB/s so this is ~48% efficiency atm, in comparison to ~80% on the quad socket istanbul system with DDR2 800 (theor. max ~51GB/s).
Particle here has an dual istanbul setup, maybe he can run a few benchmarks for comparison. Maybe stream at the same cpu and nb clock speed.

I doubt system has populated all memory channels - kinda hard with only 8GB of RAM (unless 1GB sticks are used). Best to clarify ...

s7e9h3n can you clarify memory configuration? How many DIMMs and which configuration (Single, dual, quad channel per socket)?
