I am upgrading to a Q9650 from my e7200.

I now have it at 3.9ghz! I had to loosen my memory timings to 5-5-5-16. Bios @ 1.250v and CPUID @ 1.200v. Idle temps are in the very low 30s still. Low 50s under Intel Burn Test maximum stress! I can't get to 4Ghz yet. I will keep you posted.

Frickin' awesome. Now go for overnight tests with Prime/OCCT. Once you have that settled down, save your settings and then try to get that last 100 MHz.

In my experience as well as what i've observed from others (particularly on XS, etc.), lower VID chips do tend to run hotter than higher VID ones.
But with better cooling, due to the lower voltage that tends to be needed, you can achieve better OCs, assuming you can keep heat down.

I had two E6600s.
"F" batch ran cool, higher VID
"B" batch ran hot, lower VID, clocked far higher though.

Q6700 G0 ran cool; higher VID
QX6850 G0 ran very warm; lower VID; clocked higher.

Q9550 E0 ran cooler; higher VID
Q9650 E0 runs hot; lower VID, clocks up on way less vcore.

Obviously, there is luck involved, but with two of the same stepping CPUs, chances are, the lower VID one will run hotter, but if temps can be kept in check, it will also clock higher.

I agree with this. In part because of a post of mine some time back about fast/leaky versus slower/non-leaky transistors. It seems that the faster chips are also the leakiest, and thus run hotter. At least that's been my personal experience with my E2140s and Q6600s.

Without interrupting Serra___ and Black___ in their dialogue, I'm interested in PhunkOne's IBT results. Is 58C the temperature reported by the TCase sensor?

I now have it at 4.0Ghz! Bios @ 1.300v and CPUID @ 1.264v. I think she will go to 4.1Ghz!
