Why doesn't the core speed readings on CPU-Z read a stable clock? It fluctuates from 3599.8Mhz to 3600.1Mhz Is it motherboard related or PSU related?

That's pretty darn stable. I wouldn't worry about it. It's within reason.

If its stable then I'm definately hanging on to my old P5K-E board, that thing was the shit! I never had any fluctuations on anything. Then again, i was using the Enermax Liberty 500

My wild-ass guess is that it's due to tiny electrical fluctuations in the phase-lock loop, producing a tiny variation from the electrical signal in the FSB. The clocking numbers you're dealing with are so high, my guess it's simply part of the electrical variations inherent in high-speed semiconductor architectures. I used to know a lot more about this then I now do. If you OCed a 80386-33 to 37 MHz (which I'm sure some people did) you would probably not see any variations at all, because the ceiling was so much lower. But now, with 3.3 GHz CPUs OCing to 4.3 GHz, or the equivalent quads, my guess is you're bound to see slight variations. I know next to nothing, of course.

Are you finally finished with the Q9650?

No, i'm taking it real slow. Actually been workin a lot of hours. I need to drill into the case for the RAD and it will be my first case mod of that kind. I'm excited still though! I have all the H20 parts. I should drop in the cpu and put the EK block on it just to break the ice a little bit.
