Although this motherboard offers stepless control, it is not recommended

to perform over clocking.  Frequencies other than the recommended CPU

bus frequencies may cause the instability of the system or damage the

CPU. The CPU host frequency of this motherboard is determined by the

jumper-setting. You must set the FSB jumper according to your AMD CPU

before you use the “Manual” option as the FSB setting in BIOS setup to

perform over clocking. Please check page 21 for details.
