If you have your Mobo manual, or other literature, you can usually find someplace in it that will tell you if it has a jumper free mode or not. On my ASUS, all I have to do is click a few switches over and then its in jumper free mode. Dont do me a lot of good since my CPU is a PIII, but at least the Mobo has the option. You can also check the multiplier by going into the BIOS, usually you can find info on what the clock speed is and stuff like that. If you know your way around a BIOS, it should be very tuff. If a BIOS is new territory, read up on your Mobo and try to acquire as much knowladge as you can about it. Good luck.
