Benchmarks - overclocking

The Intel-supplied Core i7 3960X chip shows overclocking promise by running at all-core 4.5GHz with additional voltage. We've used the same test platform and overclocked settings for the 3930K. Unsurprisingly, the final frequency is very similar to the 'X's.

A Vcore of 1.325V - showing higher in CPU-Z, oddly - is enough to keep the chip happy at 4,600MHz, or 100MHz higher than the sample Core i7 3960X. One multiplier jump isn't going to make a whole heap of difference in the grand scheme of things, but here are a couple of benchmarks to show what Sandy Bridge-E can do.

Now, if only those two inactive cores and four threads could be switched on! Bear in mind that increasing both the speed and voltage pushes system-wide power-draw up from 197W to 289W, putting onus on the cooling, which is a Zalman CNPS11X Performa heatsink in this case.
