Default speed of theses CPU's is 2.8GHz and the turbo will only bump that up when the processing load allows. In the case of this benchmark, turbo mode will not activate as all cores are in use. I have an Intel lab here somewhere which I can run to show the turbo in action if you like

Memory is DDR3 1066 with timings of -

CAS Latency - 7
RAS# to CAS# Delay - 7
RAS# Precharge - 7
Cycle Time - 20
Command Rate - 1T

HTH
Do you know if the Gainestown turbo mode functions any differently than the standard i7? Also what are you using to verify you're dropping out of turbo mode with all cores running? The one I found that seems to be accurate is Everest 5 under Computer->Overclock. When running 4.1GHz with 4.3GHz turbo it'll stay at 4.3 during the entire PI run (HT enabled, 8 threads total). The only time I can see it dropping out of turbo is when I get something going for extended periods of time like Prime95.

Another interesting thing may be if you run the PI test with turbo mode off and compare on/off results (if you have time). I'd love to see the turbo stuff in Intel Lab, thanks.
