I have a video problem, when i go past 430 FSB i lose more than 50% perfomance in 3D, i go from 200 fps in hl2 dm to 30-40 fps. I dont know how to resolve this, i read that its the pci-express to goes from 14x to 1x , but i put it on 101 mhz and i tried more values and i have the same problem, wtf!! I tested my pc with memtest, orthos prime for hours and hours in everything and its stable! and when i go to play hl2 or hl2dm in the first screen of the presentation of the game i have sound corruption. i also read that my memory can cause this because OCZ and Asus are not friends lol. What do you think?
PD: i tried to put the max voltages in the chipsets, fsb etc etc and the same problem. My card is 8800GTS 320 and its OC but i tested it with Atitool and its fine!
