Jumper
FSB_SEL0
(see p.2 item 30)
FSB_SEL1
(see p.2 item 29)
Note: The setting of the CPU front side bus frequency of this motherboard is by means of the
adjustment of jumper-setting. You must set the FSB jumper according to your AMD CPU
before you use the "Manual" option as the FSB setting in BIOS setup to perform over
clocking. Please follow the figures above to set the CPU front side bus frequency.
PS2_USB_PWR1
(see p.2 item 1)
Note: To select +5VSB, it requires 2 Amp and higher standby current provided by power supply.
JR1
(see p.2 item 20)
JL1
(see p.2 item 20)
Note: If the jumpers JL1 and JR1 are short, both the front panel and the rear panel audio
connectors will work.
Clear CMOS Jumper
(CLRCMOS2)
(see p.2 item 24)
Note: CLRCMOS2 allows you to clear the data in CMOS. The data in CMOS includes system
setup information such as system password, date, time, and system setup parameters. To
clear and reset the system parameters to default setup, please turn off the computer and
unplug the power cord from the power supply. After waiting for 15 seconds, use a jumper
cap to short 2 pins on CLRCMOS2 for 5 seconds. However, please do not clear the CMOS
right after you update the BIOS. If you need to clear the CMOS when you just finish
updating the BIOS, you must boot up the system first, and then shut it down before you
do the clear-CMOS action.
FID Jumpers
(FID0, FID1, FID2, FID3, FID4)
(see p.2 item 2)
Note: The set of FID jumpers are designed to adjust the multiplier of CPU. For detailed information,
please refer to page 15 of user Manual in the Support CD.
