The only jumper listed for this board on asus website is the "overvolt jumper" near the cpu socket. I would also look for a "jumperfree mode" jumper on this board in the manual; my last asus board had this jumper, and it had to be set properly to access the bios settings. Read your manual carefully, and you should be able to adjust the voltage. I would download the manual and check for you, but my downloads are pretty slow.
