Overclocking my Q6600 problems?

Ok downloading HW Monitor now ;)

Yeah, need to know what the voltage is dropping to, if at all (but I think its dropping a lot). Those errors from Prime sound like lack of CPU voltage.

Oh and make sure you are checking the individual core temps when loaded. These are pretty accurate in HW Monitor too, which is handy :)
 
Ok was running Prime95 for about 5 minutes, then got a blue screen once again, when I was looking the Vcore on HW Monitor was stable @ 1.4 but the +12 did change a bit.
 
I must say I am very VERY surprised if vcore didn't move at all!

Okay, next thing to try...

CPU RATIO - 9x
FSB - 333
CPU Vcore - 1.45
CPU PLL - 1.55
Northbridge - 1.35
FSB Termination - 1.25

EDIT - what were your Northbridge temps like?

So far so good, CPU VCore has not changed value is 1.38, min is 1.38 max is 1.42, don't know how to check Northbridge temps though!

Right trying Prime etc now! Unsure what the Northbridge temps were, sorry, I will see on this try ;)

No worries. Can you upload a screenshot of HW Monitor please? Both idle and full load if you can.

EDIT - you say CPU vcore is 1.38, did you set it at 1.45 in the bios? If so, then the drop is 0.07v under load, which we need to allow for. Nothing to worry about, but need to allow for it when overclocking. That would explain the blue screens at 1.35 and 1.4v as your actual readings would've been 1.28 and 1.33 under load.

Ahh right, yes it is, think it shows it in the pics ;) ^

EDIT: Forgot to mention yeah I did set it to 1.45 in bios =]
 
Thanks for the pics. I will see if I can work out how you can get your Northbridge temp.

In the meantime, did Prime crash?

Nope Prime did not crash when I ran it ;P, had to stop to take pic tho! Will try again. Also wanted to say thanks a lot for the help mate ;)

No problem at all, happy to help. Ignore CPU-Z, quite often it can be a little out.

Good to know Prime stability seems to be getting closer anyway. You need to run it again for a good while to be sure its stable. Lots of folks recommend 12hrs, but if it runs for 30mins - 1hr I have always found thats good enough for me. ;)

Try Everest (trial) to see if it reports Northbridge temps etc.

Ok awesome, I'll give it a go for 30 mins - 1 Hr and post again, if you'll still be on then?

Downloading Everest now so will update you in a sec ;)
 
Fairly certain it is, on my board, that's the only reading that's affected by increases in NB voltage.

If you've only got 2 sticks of ram, its shouldn't need much - 1.3v or maybe a touch more. You'll find that it gets hotter in games than Prime as all the hot air from your GPU goes over it.
 
Ran prime for around 40 minutes and everything is fine, no errors =]

Edit: Although my min on CPU VCore has gone down to 1.37
