stock clock multi is 10.5x i have noticed that if my processor even touchs 40c my computer locks up in windows i did manage to get it to about 2.4ghz stable but only for a hour if that and all i would be running is cs1.6 with the cpu stock i hit around 37c under full load for about a hour or so. one thing i did was change out the 8pin power plug for the motherboard to the 4pin and it started working a lot better it killed all of those overclock failed flags but now if i take my cpu voltage over 1.38v or my ram v over 1.9v it fails. idk its pretty odd i spent about 4 hours one day with a pen and pad of paper adjusting everything i could think of i also cant change the htt multi or the ram devider in the bios but i can change the htt multi in amd overdrive.
