Overclocking the Yorkfield/QX9650

This is a very exciting thing for me.  I've been waiting for Penryn and 45nm Core 2's for a very long time.  Why?  Because every die shrink is another opportunity to see how much overhead and overclocking bliss one can achieve.  I must say that overclocking the QX9650 was a pleasure.  Here are some CPU-Z screen captures so you can see how far I got even before you look at the overclocked results :-)

3.6GHz - piece of cake, default voltages.

4.25GHz - had to work for it:

• Vcore at 1.575V (Dangerous without really good cooling)
• Vdram at 1.8V
• Vmch at 1.5V
• Vfsb at 1.45V

But once I got it stable, it was really sweet!

4.5GHz - booted into Windows, but extremely unstable. With better cooling it should be achievable!
