Very nice OC for the Q6600! How stable is it with that voltage?
I think the FSB wall varies slightly in each board... you'll just have to test it and see!
If you hit the wall, you need to go past it, simple.
The DLL file works fine.
I was wondering what the trick to this old program is, I get about 1/2 the score I should with any hardware that I test, running Vista 64bit/windows 7 64bit. I have the X64 patch too, it doesn't work without.
As others stated,the first step is to get better cooling than that stock air, then you can pump lots of Vcore into that thing and get closer to 4ghz, depending on your cooling!
