I got an i5 2500 running at 3.3Ghz but it has Intel Turbo which supposed to kick it up to 3.7Ghz when then the power is needed, I'm using CPU-Z to see the clocks and it's always at 3391.91Mhz and never close to thr 3.7Ghz, my temps are fine, always running max 50C, I also have the Turbo feature turned on in BIOS but still the turbo nevers turns on, even when benchmarking.
