this memory is ddr500 and I am running it on asus p4c800e-dx with third party bios that lets me choose ddr500 and ddr533 as well.I can get the pc to boot into windows if i choose ddr500 or ddr533 but for some reason my overclocking wont go as high as before. If i run ddr400 I can oc my processor up to 3.5ghz but on ddr 500 i can oc to is about 3.1ghz? anyone has any suggestions on what might be holding me back? memory is running voltage at 3.5v I dont wanna risk it by going any higher
