ok I'm having some real problems maintaining system stability. I'm fairly sure that heat is not the problem, and I know this 600e does 850+, but it won't remain stable even at 800 unless I use the pre-configured 800(133) option in bios. If I try to set it manually at 133 or higher I just keep getting an "error accessing windows registry" when I get to the desktop while booting. Please does anyone have any ideas?!
