I just installed this cpu in my computer and am only getting 2.66 on both cores. It should be 3.0. My buss is 1333. My mb is a Gigabyte P35C-DS3R. I'm not trying to overclock, just want it to run at 3.0 like it's supposed to. Thanks for help on this.

Ok what is the likely cause is Windows Device Manager has not updated from the e6750 at 2.66Ghz to the new e8400 3Ghz processor. The easiest way I know to correct this is to open device manager and uninstall the two CPU drivers from there. Restart the system and the e8400 will be detected by Windows.

You might also run a program like CPUID or CPU-Z to see what multiplier the machine is running at. If it is idle and speedstep is active it should show a multiplier of 6 but under load it should jump to 9.
