enigmadoubtful; some chips just overclock better than others
have you considered just using a lower fps_max and adjusting your other accel settings accordingly?
yeh if I can't get this working I'll prob just do that until I can get a new system/parts
the weird thing is while my computer just freezes if I try going to 4.6ghz, after playing around in the bios it seems stable @ 4.5? (see link above) however 20 minutes later it just randomly blue screens
maybe its not my cpu, computers lol
