What I did for mine was 20 passes of IBT at max settings( 5 passes to check the OC) and then prime95 on blend for 8-10 hours. I just turned it on 2 hours before I went to sleep and checked it in the morning. I also ran IBT and prime95 small fft's together for an hour but that was just to see if I could. Check the temps before leaving it run unattended. My temps top out at around 68c-71c. Ultimately you'll need to game with it. If it doesn't crash in game I'd say it's fine.
And here's an 11th answer.
I run prime for a grand total of 15 minutes. Yes--15 minutes.
The reason being:
If I can pass ONE loop (one loop takes 15 minutes, and this is usually 15 iterations of small FFT or around 10 iterations of "Blend"), then my computer is stable enough to "attempt" gaming without being so unstable that it could hose the OS. Also, RAM/memory errors (due to too high timings, too high frequency, etc), will *ALWAYS* be caught within the first 15 minutes, and usually within the first 1 minute. RAM errors are less likely to cause a BSOD than CPU errors, unless the RAM Errors are extreme. I Tried running my 1333 RAM at 1600, at auto timings and I forgot the voltage (1.58), and instead of a BSOD, every single prime blend thread failed in the first 20 seconds.
I let the games themselves be the stress test. I'd rather blow up my cpu by playing games, than running something that heats the chips up higher than even vantage CPU test or Deep Rybka 4 chess engine. But that's just me.
And also, in my experience, if you can't pass ONE 15 minute loop of prime blend, you *WILL* BSOD in your games (Depending on if the game is multi or single threaded; Single threaded games can run at significantly lower voltages).
I haven't done extensive testing at 5 ghz on my new CPU, as 4 ghz is my 24/7 settings--deliberately--so I have more cpu power to unlock later when I need it
(the only thing I did was play black ops for awhile, with zero bsod's), but I'll try some Bad company 2 and other hard hitting stuff and see if that BSOD's or not.
