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.

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.
1.8.4 AGP slot
The Accelerated Graphics Port (AGP) slot that 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 (CLRTC1)
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 CLRTC1 jumper
default position. Removing the cap will cause system boot failure!
P4S800D
P4S800D 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 default values.

Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU
stopped, DRAM refreshed, system running in low power mode) using the
connected USB devices. Set to +5VSB to wake up from S3 sleep mode (no
power to CPU, DRAM in slow refresh, power supply in reduced power mode).
Both jumpers are set to pins 1-2 (+5V) by default because not all computers
have the appropriate power supply to support this feature.
The USBPW12 and USBPW34 jumpers are for the rear USB ports. The
USBPW56 and USBPW78 jumpers are for the internal USB header that you
can connect to the front USB ports.
1. This feature requires a power supply that can provide at least 1A on the
+5VSB lead when these jumpers are set to +5VSB. Otherwise, the system
would not power up.
2. The total current consumed must NOT exceed the power supply capability
(+5VSB) whether under normal condition or in sleep mode.
3. The rear panel USB ports (Ports 1 to 4) do not support device wake-up
from S4 sleep mode.
