This jumper is used to specify the relationship of PCI and FSB clock. Generally speaking, if you are not overclockers, we
recommend you to set at the default setting. By the way, this motherboard also provides “1MHz Stepping Adjustment” feature for
overclockers. You can adjust CPU FSB frequency via BIOS setup program. Based on the CPU type, the adjustment range has
three level: 66~90 (FSB=66MHz, such as Celeron™ 533), 100~127 (FSB=100, such as Pentium
®
III 800E), 133~248 (FSB=133,
such as Pentium
®
III 800EB) MHz for your choosing. If you fix the CPU FSB frequency by JP23, the “1MHz Stepping Adjustment”
range will be changed and following your JP23 setting.
