We came to Intel with great expectations. We were about to embark on another adventure in the Intel laboratory and overclock another generation of Intel processors. The last two times we were quite pleased with how the systems performed, even though it took a lot of time and energy to get those system stable and running at the world record frequencies we were trying to reach. This time we had done what we came to do and even surpassed our goals a whole day ahead of schedule. This is the most mature prelaunch platform we've played with yet. Nehalem has delivered.

You just should forget everything you've read at Fudzilla and TheInq about how this is done and what problems there might be. The stories about how Intel would lock overclocking through synchronized bus controllers in the CPU and northbridge, problems the synchronized voltages etc, they have just been a bunch of lies. Some of the stories haven't don't even contain a single ounce of truth or even the slightest fact from reality. Maybe in a slightly distorted dimension on another planet, but the reality is that Nehalem overclocks and considering how much trouble we had when overclocking Kentsfield and Yorkfield, Nehalem has been a lot more stable.

You are going to overclock Nehalem just like any other new system. Just a new bus and new voltages to get used. Overclocking is here to stay.
