Could this be PSU related?

I've managed quite a decent overclock on my E6300, but I'm having a strange problem. Everythings good, until I try to warm boot, and then each time the BIOS tells me the overclock has failed and to press F1 to reset. Each time none of the settings in the BIOS have changed and it continues to boot as normal. From a cold boot everything is as I should be, boots fine.

System is a E6300 on an ASUS P5K. 2Gb of OCZ Gold XTC PC2-6400. Running FSB at 429 and upped the vCore to 1.3250. Could the PSU be causing this (wild stab in the dark) or do I need to up the voltage to the CPU (reluctant as temps are good). Current PSU is a Antec Smartpower 350, could this be the problem. I intend to upgrade the PSU anyway, could this be my system telling me to do it now??

As you can see, I reckon the overclock is stable.

Tried increasing the voltage to the CPU in steps all the way to 1.45 yet the problem with restarting remains. Can anyone offer any advice please?

I'm no expert, but had a simular problem with my Q6600 I just upped the volts on the memory and it worked, I have no Idea why!

Your PSU seems to be powerful enough, unless you have lots of extra cards & drives added. I have a 3GHz Pressler running 24/7 on an old 250W PSU!

Its a nice OC wish my Quad was that good.

I think it could well be. A 350 was ok on NF2 rigs, but in all honesty, they just arn't up to it with a modern rig. You will probably struggle to get a better clock with your current rig, unless you can give it more power, and a more stable power source as well.
