Important notes
•
Installing DDR DIMMs other than the recommended configurations may
cause memory sizing error or system boot failure. Use any of the
recommended configurations in Table 1.
•
•
Use the blue DIMM slots first.
In Dual-channel configurations, install only identical (the same type and
size) DDR DIMM pairs for each channel.
•
Always install DIMMs with the same CAS latency, otherwise, the system
may run in a lower frequency. For optimum compatibility, it is recommended
that you obtain memory modules from the same vendor. See list of
Qualified Vendors List on page 1-10.
•
When all four sockets are populated with 1GB DIMMs (Total 4 GB), the
system may detect only 3+ GB (a little less than 4 GB) due to the
SouthBridge resource allocation.
•
•
Three DDR DIMMs installed into any three memory sockets will function in
single channel mode.
Make sure that the memory frequency matches the CPU FSB. Refer to
Table 2 for configurations.

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!

P4P800-X 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.

2. USB device wake-up (3-pin USBPW12, USBPW34, USBPW56, USBPW78)
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 and S4 sleep
modes (no power to CPU, DRAM in slow refresh, power supply in reduced
power mode).
The USBPWR12 and USBPWR34 jumpers are for the rear USB ports. The
USBPWR56 and USBPWR78 jumper is for the internal USB connectors that
you can connect to additional USB ports.
•
The USB device wake-up feature requires a power supply that can provide
500mA on the +5VSB lead for each USB port; otherwise, the system would
not power up.
•
The total current consumed must NOT exceed the power supply capability
(+5VSB) whether under normal condition or in sleep mode.

2.2 BIOS Setup program
This motherboard supports a programmable firmware hub (FWH) that you can
update using the provided utility described in section “2.1 Managing and updating
your BIOS.”
Use the BIOS Setup program when you are installing a motherboard, reconfiguring
your system, or prompted to “Run Setup”. This section explains how to configure
your system using this utility.
Even if you are not prompted to use the Setup program, you may want to change
the configuration of your computer in the future. For example, you may want to
enable the security password feature or change the power management settings.
This requires you to reconfigure your system using the BIOS Setup program so
that the computer can recognize these changes and record them in the CMOS
RAM of the firmware hub.
The firmware hub on the motherboard stores the Setup utility. When you start up
the computer, the system provides you with the opportunity to run this program.
Press <Delete> during the Power-On Self Test (POST) to enter the Setup utility.
Otherwise, POST continues with its test routines.
If you wish to enter Setup after POST, restart the system by pressing <Ctrl> +
<Alt> + <Delete>, or by pressing the reset button on the system chassis. You can
also restart by turning the system off and then back on. Do this last option only if
the first two failed.
The Setup program is designed to make it as easy to use as possible. It is a menu-
driven program, which means you can scroll through the various sub-menus and
make your selections from the available options using the navigation keys.
The default BIOS settings for this motherboard apply for most conditions to
ensure optimum performance. If the system becomes unstable after changing
any BIOS settings, load the default settings to ensure system compatibility and
stability. Select the Load Default Settings item under the Exit Menu. See
section “2.7 Exit Menu.”
The BIOS setup screens shown in this chapter are for reference purposes only,
and may not exactly match what you see on your screen.
