Well I asked someone to get me ram and am wonderin if I can put a ddr2 533 stick of ram in with the rest of my ram? I know it will prob perform as my regular ddr 400 does would it make my ddr400 ram use its higher timings aswell? Just wondering, I asked the guy to see if he could get me some good quality ram. my system takes ddr400 or ddr2 533 ram. Thanks!
