This motherboard is CPU jumper-less design, you can set CPU frequency through the BIOS setup, and no jumpers or switches
are needed.
BIOS Setup > Frequency/Voltage Control > CPU Speed Setting
CPU Ratio
From 5.5x to 16x step 0.5x
CPU FSB (Adjustment
manually)
FSB=100~200 by 1MHz Stepping CPU Overclocking
Warning: nForce2-ST/G/GT chipsets support 166MHz FSB (with performance
reaches maximum 333MHz EV6 system bus) and 66MHz AGP clock, higher clock
setting may cause serious system damage.
Tip: If your system hangs or fails to boot because of overclocking, simply use <Home>
key to restore the default setting or you can wait the AOpen “Watch Dog Timer” reset
the system after few seconds and system will auto-detect hardware again.
