Overclocking Nehalem Detailed
 

There had been a lot of rumors about the overclocking capabilities of the Core 2 successor. Today we learned that the Nehalem top model (default clock speed is 3.2 GHz) was running stable at 4 GHz. More OC details were revealed, too. As usual with chipsets, you need to adjust the multiplier. The QPI connection between the CPU and the chipset got a own value that you need to lower.

In the producer's test 1.7 volt were enough for 4 GHz. Furthermore the Nehalem is said to be quite cool during the procedure - air cooling is sufficient. According to the producer, more than 1.65 volt is dangerous to the integrated memory controller.

1.7 Volt was enough !? I bet it was enough :s

I hope they mean 1.3 or something ?

I think they actually mean 1.7v otherwise the 1.65v is a typo too:)
I agree that these numbers are way too high for daily use:D

Was worried about this. From Anandtech:
