That may be so, but in all the time I've primed systems I've never had an unstable one that went stable in Prime for 6hrs +. I would rather test it with Prime first before opening up all sorts of applications to test it with, because it can corrupt your files if you don't have a stable overclock. (or are you talking about a program like Orthos? Maybe I'm misunderstanding you here.)
I'll also run the Windows Memtest to make sure the RAM's stable as well.
