This jumper allows you to select your host CPU frequency. For 133/166MHz FSB, please set the pin to 1-2; and for 100MHz
FSB, please set it to pin 2-3. Generally speaking, if you are not overclockers, we recommend you to set it to the default setting.
Additionally, this motherboard also provides “
1MHz Stepping Adjustment
” feature for overclockers to adjust CPU FSB
frequency via BIOS setup program. The adjustment range is 100~200MHz. If you fix the CPU FSB frequency by JP21, the
“1MHz Stepping Adjustment” range will be changed and following the JP21 setting.
