Hi. I have an AMD 965 phenom x4 and changed 1 of the options in bios to run at 3.8ghz, something like x18 I think it was and left everything else on auto. Have I done it properly or do I need to change anything else. All checks have shown run speed of 3.8ghz up from 3.4ghz. Mobo is Asus M5A78L-M/USB3. Windows 7 x64.
