XtremeSystems user PcCI2iminal has just posted some first overclocking results of the recently launched Core i7 920 D0 stepping 5 processor. Although his results were taken with an engineering sample CPU, they seem to be on par if not slightly better than what is achievable with the C0 stepping.


Validation

According to the results, 4,641MHz was achievable with a vCore of 1.56v and a 221MHz BClock speed. It can also be noted that the maximum Prime95 stable BClock at boot up was 222MHz with CPU VTT, PLL, and northbridge voltages at a minimum.

The setup used was a Biostar TPower X58 running beta BIOS 080015, combined with A-Data 1600MHz DDR3 and a Thermalright Ultra-120 eXtreme-1366 RT for cooling.
