ok i bought a ati 9600 xt, and was ocing it. I bought the vga artic silent cooler and installed it, but it didnt fint on my mobo, so i had to put on old HS and fan. ANyways, after i re installed it, i can still OC a little, cause i got ram sinks, and i magane to score 5000 3d 03 marks. However, in any gaming, ad benchmark, i get mad lag every like 30 seoconds. Like, its fine, then stalls for a half second, then resumes, it dont mess with fps on 3d mark i guess, but i want to know what to do about this! I alreayd tried defragging, and that didnt help. any ideas?!?!!
