I built a new computer, athlon64 4000+, msi k9a crossire, 2gigs gskill ddr2 pc6700, raptor 10k, x1950pro. 550watt ps. 22" hannsg lcd. I can and do oc cpu to 2.85g stable, I don't do anything to memory, but I would like to oc my video card up alittle. I can click on ccc and it tells me I can go higher in clock and core, but I raise it half that and play a game(bf2 2142) for 10 min I get artifacts, and I stop playing. I can then open ati ccc and it has a temp of only 50c, normal is 40c.? I've heard that some of these cards have been put together in a hurry and the heatsink fan is not set very good. Any ideas? I dont think its ps, and if its the heatsink why would ccc just read 50c at max. Its a good card and runs well, but I should be able to get more out of it. Just alittle higher will artifact in 10min.? Thanks EnginRob ps if I need to reset my fan- heatsink, how?
