Chapter 1: Product introduction
1.7.3 Installing a DIMM
Follow these steps to install a DIMM.
1. Unlock a DIMM socket by pressing the
retaining clips outward.
2. Align a DIMM on the socket such that the
notch on the DIMM matches the break on
the socket.
3. Firmly insert the DIMM into the socket
until the retaining clips snap back in place
and the DIMM is properly seated.
A DDR DIMM is keyed with a notch so that it fits in only one direction. DO NOT
force a DIMM into a socket to avoid damaging the DIMM.
1.8 Expansion slots
To install and configure an expansion card:

Unlocked
1. Install an expansion card following the instructions that came with the chassis.
2. Turn on the system and change the necessary BIOS settings, if any. See
Chapter 2 for BIOS information.
3. Assign an IRQ to the card. Refer to the tables next page.
4. Install the drivers and/or software applications for the expansion card
according to the card documentation.

When using PCI cards on shared slots, ensure that the drivers support “Share
IRQ” or that the cards do not need IRQ assignments. Otherwise, conflicts will
arise between the two PCI groups, making the system unstable and the card
inoperable.
1.8.3 PCI slots
The PCI slots support PCI cards such as a LAN card, SCSI card, USB card, and
other cards that comply with PCI specifications.

The Accelerated Graphics Port (AGP) slot supports AGP 8X/4X (+1.5V) cards.
When you buy an AGP card, make sure that you ask for one with +1.5V
specification.
Note the notches on the card golden fingers to ensure that they fit the AGP slot on
the motherboard.
Install only +1.5V AGP cards.

1.9 Jumpers
®
1. Clear RTC RAM (CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS.
You can clear the CMOS memory of date, time, and system setup parameters
by erasing the CMOS RTC RAM data. The RAM data in CMOS, that include
system setup information such as system passwords, is powered by the
onboard button cell battery.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on
pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and enter BIOS setup to
re-enter data.
Except when clearing the RTC RAM, never remove the cap on the jumper
default position. Removing the cap will cause system boot failure!
K8V
K8V Clear RTC RAM
You do not need to clear the RTC when the system hangs due to overclocking.
For system failure due to overclocking, use the C.P.R. (CPU Parameter Recall)
feature. Shut down and reboot the system so BIOS can automatically reset
parameter settings to its previous values.

This jumper allows you to enable or disable the keyboard wake-up feature. Set
this jumper to pins 2-3 (+5VSB) if you wish to wake up the computer when you
press a key on the keyboard. This feature requires an ATX power supply that
can supply at least 1A on the +5VSB lead, and a corresponding setting in the
BIOS.
