FSB1 / FSB2 / FSB3 Jumper (FSB1, 3-pin jumper, see p.10 No. 26) (FSB2, 5-pin jumper, see p.10 No. 26) (FSB3, 5-pin jumper, see p.10 No. 26) FSB1 FSB2 FSB3 Default Standard Setting: If you adopt below DRAM / CPU configuration on this motherboard, you need to adjust the jumpers. Please follow the instructions below to set up the jumpers. Otherwise, the CPU and memory module may not work properly on this motherboard. DRAM CPU Jumper Settings DDR3 533 FSB533 FSB1 FSB2 FSB3 DDR3 1333 FSB1333 FSB1 FSB2 FSB3 FSB1: 2-3 FSB2: 1-2 FSB3: 2-3 FSB1: 1-2 FSB2: 4-5 FSB3: 1-2 Overclocking Setting: When you mount a FSB800 or FSB1066 CPU, and try to overclock to FSB1333 (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 pin2, pin3 for FSB1 jumper, 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. FSB1 FSB2 FSB3 If you want to overclock the CPU you adopt to FSB1333 on this motherboard, you need to adjust the jumpers. Please short pin2, pin3 for FSB1 jumper, short pin3, pin4 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. FSB1 FSB2 FSB3 19
