So I've had my Q6600 a month. The day I got it I set it to 3.0Ghz at stock VCore (1.3125v?) and its been absolutely fine ever since.

Today I thought I'd go further. Went for 3.2Ghz but I get a BSOD after just 1 minute of Prime 95, even at 3.3325v. What gives?

Using an Arctic 7 Freezer Pro. My load temps at 3Ghz whilst running Prime are in the 70's on two of my Cores, but in the 60's on the other two. Is this wrong?

Yikes! 3.3325v! And it lasted a minute or so?

Probably a typo for 1.3325v. But that isn't really much more than your original voltage. As you OC you need to put more into the chip. Not that I'm any expert, but to get to to 3.6 mine is sitting at 1.4625 in the BIOS. This actually drops to 1.4 ish in real terms (according to CPU-Z) at idle. Under load it drops even further (vdroop) to 1.38-9.

I saw this with OCCTPT (testing software linked on this site) which draws a graph of the voltage as the CPU is put under sress.

So, to answer your question, and as long as 3.3325 is a typo, don't be too shy with the vcore voltages.

If you're getting a BSOD then I'd suspect the RAM is being overclocked to a point it doesn't like so post all the settings you used at 3ghz and at 3.2ghz.

just watch those temps fella!!!!!!!!

my Q6600 with a freezer 7, used to idle at 55c (3.0ghz) and full load was above 70c! above 70 is regarded as to warm,
I changed my cooler and now I idle at 40c @ 3.6ghz @ 1.44v via cpu-z
to give you a picture of my temps underload (and mine still are not brilliant)
load on prime95 approx 60c now
intel burn test takes it back to 70c but is a beast for temps though!
games load approx 55c

are you able to up the pro7 fan speed in the bios? if you have it connected like that?

there will always be a difference in temps between cores generally 2 are cooler by a fair bit, just take your highest temp core and go by that

60'c is quite good for 3.6ghz p95 small fft test, i was hitting 68-68-62-62 @3.6ghz, 1.4 vcore. Ended up lapping my cpu and TRUE before moving to 3.8ghz, 1.512v and 2 more powerful fans, temps were still 68-68-62-62. Even after lapping theres still a bit of a variation.:(

Post up some CPU screenies showing both the memory tabs please!

Also not sure an Arctic 7 Freezer Pro should be giving up to 10°C difference in load temps across the four cores?
 
those pesky push pins are a pain to get a good even pressure with... 10c across the cores isn't anything to worry to much about although you might consider lapping the CPU if you really want more even temps. That said lapping will do you no good if one set of cores is getting a better/worse contact with the IHS... so swings and rounder bouts...

As to your BSOD... I would increase you NB voltage by 0.1v and up the vcore to 1.4v, make sure that your RAM isnt running above 800mhz and loosen the timmings out to 5-5-5-23 and double check you are giving it the more voltage recommended by the manufactures... should get you stable

If the above is stable, slowly lower the vcore until you become unstable again to find the minimum voltage needed for the clock and work up from there :)
