Before you proceed  
Take note of the following precautions before you install motherboard  
components or change any motherboard settings.  
Unplug the power cord from the wall socket before touching any  
component.  
Use a grounded wrist strap or touch a safely grounded object or  
to a metal object, such as the power supply case, before handling  
components to avoid damaging them due to static electricity  
Hold components by the edges to avoid touching the ICs on them.  
Whenever you uninstall any component, place it on a grounded  
antistatic pad or in the bag that came with the component.  
Before you install or remove any component, ensure that the ATX  
power supply is switched off or the power cord is detached from  
the power supply. Failure to do so may cause severe damage to the  
motherboard, peripherals, and/or components.

System memory  
1.7.1 Overview  
The motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline  
Memory Modules (DIMM) sockets.  
A DDR2 module has the same physical dimensions as a DDR DIMM but has  
a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are  
notched differently to prevent installation on a DDR DIMM socket.  
The figure illustrates the location of the DDR2 DIMM sockets:  
P5GC-MX 240-pin DDR2 DIMM Sockets  
Channel  
Sockets  
Channel A  
Channel B  
DIMM_A1  
DIMM_B1  
1.7.2 Memory configurations  
You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered non-ECC DDR2  
DIMMs into the DIMM sockets.  
For dual-channel configuration, the total size of memory module(s)  
installed per channel must be the same (DIMM_A1 = DIMM_B1).  
Always install DIMMs with the same CAS latency. For optimum  
compatibility, it is recommended that you obtain memory modules  
from the same vendor. Refer to the DDR2 Qualified Vendors List on  
next page for details.  
This motherboard does not support memory modules made up of  
128 Mb chips or double-sided x16 memory modules. .

2.2  
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+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. 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 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 section are for reference  
purposes only, and may not exactly match what you see on your  
screen.
