i7 4770k issue

[Bucks79]

Hey guys

Ive been overclocking my cpu and have everything stable at 4.2ghz. I run stress tests for hours and the temps are good and everything ok. Then when I boot up a game etc I get a restart and overclocking failed message. Anyone got any ideas?

Cheers

try adding or lowering the voltage slightly it might help with stability
