I'm a new member of these forums but i've been visiting this site for some time now. I've tried to find a solution for this problem for a couple of hours but i couldn't find anything useful so I'm sorry if there are other threads about this.
I have used my Amd x4 955BE at 3,4ghz with stock voltage ~1,34v for almost a year now without problems so i decided to try to oc it a bit more because the temps were cool and extra performance was welcome. So i got it to 3,6ghz with 1,44v and ran prime95 for a couple of hours and it was stable with the max temp at 58C. All the games ran well like they should but when i went to some mmo's bigger pvp fights with dozens of other players, I noticed the fps to drop to 2 - 5 for 5-10 seconds. Then I ran prime95 again and I noticed that the cpu's vcore dropped to 1,06 for that time and then went back up! I've tried to raise the voltage to 1,49 and the LLC option in bios at different percentages but nothing seems to help. This doesn't happen at the stock voltages in which I can use the cpu at 3,4ghz. Any ideas? All the help is apprecitiated and thanks in advance!
