ya i'm not sure there is any perfect test... other than running the programs you use and seeing how well it goes.

on my most recent 400 FSB clock i crunched small FFT's a while then did 90 minutes of a blend test... everything seemed stable and working well.

until i was just playing supcom for about an hour and had a ton of units on the screen and it reboot crashed. =/ =/ i tweaked a couple volts and when i go to bed tonight i might just leave it blend testing...
