To adjust your cpu and ram speeds, you will have to access your pc's bios. Usually you just press f1, f2, del, or another key to enter the bios when the pc is first booting. It also usually has a message at the bottom of the screen like "press ** key to enter setup/bios". In the bios there are usually many adjustment options. Be aware that if you have an oem system, like a dell, hp, emachine, etc, your bios may not have adjustment options.
