I've got my Q6600 running under an H50 with CPU voltage at around 1.46V. I've been playing a bit of COD and got a blue-screen. CoreTemp was saying temperatures were around 60c, which I thought more just about acceptable?

Upped the voltage by 0.1V and things were even worse, with the temperatures pretty much the same. I'm not an overclocking expert, so could anyone point me in the right direction where I'm going wrong?

IP35 Pro
Q6600 G0 Stepping - Corsair H50 cooler.
2x2GB Ballistix 1066Mhz @956.

Cheers.

EDIT: Running at 3.4Ghz

1.46v seems a bit high to me. I have the exact same model Q6600 which I run at 1.325V@3GHz currently. The chip was orginally overclocked by OCUK as thats where I bought my rig. They used 1.47V to get it to 3.0GHz, I was getting screen tearing on the password entry screen to windows and the system felt unstable to me, so I lowered the voltage down to stock and it feels so much faster and more stable.

Whats your VID and current CPU speed?
 
1.46v is not high. Mine is sat happily at 1.525 @ 3.6ghz. 12hour prime stable, max temps 68c

As above, could be your motherboard not liking that fsb
 
Put it at all at stock setting and disable all the speed step type stuff and set pcie to 100. Test to find out the default vcore (under load). Now set this vcore in bios and overclock to 3.2ghz.

If it fails and you need to raise the vcore up then it is not stable on a lower voltage.

I use the following
Gigabyte P45 (ds3p)
OCZ platinum pc6400 (4x1gb) 5-5-5-15
400fps x 9 multi
Corsair H50
A very cramped Antec Sonata 2 case (leave the side panel off otherwise temps increase by 15-20c!)
2 x Noctura P12 fans in push/pull all exhausting
no other fans in case
