1.7.1 Overview
The motherboard comes with four 184-pin Double Data Rate (DDR) Dual
Inline Memory Modules (DIMM) sockets.
The following figure illustrates the location of the sockets:
P5GV-MX
P5GV-MX 184-pin DDR DIMM Sockets
1.7.2 Memory Configurations
You may install 256 MB, 512 MB and 1 GB unbuffered non-ECC DDR DIMMs
into the DIMM sockets using the memory configurations in this section.
•
•
•
•
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.
Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor. See Table 2 for qualified DDR DIMMs.
Due to chipset limitation, DIMM modules with 128 Mb memory
chips or double-sided x16 memory chips are not supported in this
motherboard.
When you installed four 1 GB DDR memory modules, the system
may detect not more than 3 GB of total system memory because of
address space allocation. This limitation applies only to systms with
Windows® XP 32-bit operating system since it does not support PAE
(Physical Address Extension) mode.
•
If you installed Windows® XP 32-bit operationg system, we
recommend you to install not more than 3 GB of system memory.

Chapter 1: Product introduction
Recommended memory configurations
For dual-channel configuration, the total size of memory module(s)
installed per channel must be the same to ensure optimum
performance. (DDR_A1 + DDR_A2 = DDR_B1 + DDR_B2)

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 onboard
button cell battery powers the RAM data in CMOS, which include
system setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Remove the onboard battery.
3. 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.
4. Re-install the battery.
5. Plug the power cord and turn ON the computer.
6. 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 CLRTC
jumper default position. Removing the cap will cause system boot failure!

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 the BIOS
can automatically restore parameter settings to default values.

BIOS setup program
This motherboard supports a programmable firmware chip 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 can change
the configuration of your computer in the future. For example, you can
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 <Del> 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> + <Del>, 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. Being
a menu-driven program, it lets you 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 to 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.”
