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.
