I don't deal with stuff like that so... For real life stability i use compiling since i'm a Linux user. Compiling brings my temps to around 55-58C so i think it's pretty stressfull.

BTW: by Orthos stable i mean 8 hours Orthos stable. At my current settings (in my sig) i'm Orthos stable for around 3 hours or so then an error pops out of the blue on one of the cores. I agree that if Orthos craps out in less then 30mins then you should not consider those settings as stable IRL.
