Trying to run my E4400 at 2.2ghz with stock cooling and voltage. It's stable in games and can do orthos for a few hours with no problems (haven't tried longer) but when I put the computer into standby, on resuming from standby it usually hangs and even if it does get into Windows it gives me a "program failed to initialize" when I actually try to do anything. TAT says I'm running at 60 Celsius at full load, so it's not a heat issue.
