When you mount a FSB800 or FSB1066 CPU, and try to overclock to FSB1333 or
FSB1600 (by BIOS setting) you may face the problem, that DRAM frequency will be
overclocked very high. Please use jumper to force NB to be strapped at higher
frequency, so the DRAM can work at lower frequency.
If you want to overclock the CPU you adopt to FSB1066 on this motherboard, you need
to adjust the jumpers. Please short pin4, pin5 for FSB2 jumper and pin4, pin5 for FSB3
jumper. Otherwise, the CPU may not work properly on this motherboard. Please refer to
below jumper settings.
