The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is "Short". If no jumper cap
is placed on pins, the jumper is "Open". The
illustration shows a 3-pin jumper whose pin1
and pin2 are "Short" when jumper cap is
placed on these 2 pins.
Jumper
PS2_USB_PWR1
(see p.2/3 No. 1)
Note: To select +5VSB, it requires 2 Amp and higher standby current provided by
power supply.
Clear CMOS Jumper
(CLRCMOS1)
(see p.2 No. 24 or p.3 No. 23)
Note: CLRCMOS1 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 pin2 and pin3
on CLRCMOS1 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.
FSB1 Jumper
(FSB1, 3-pin jumper, see p.2 No. 34 or p.3 No. 33)
FSB2 Jumper
(FSB2, 5-pin jumper, see p.2/3 No. 9)
FSB3 Jumper
(FSB3, 5-pin jumper, see p.2/3 No. 9)
When you mount a FSB800 or FSB1066 CPU, and try to overclock to FSB1333
orFSB1600 (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.
