Central Processing Unit (CPU)
This motherboard comes with an AM3 socket designed for Phenom™ II / Athlon™ II /
Sempron™ 100 series processors.
The AM3 socket has a different pinout from the AM2+/AM2 socket. Ensure that you use a
CPU designed for the AM3 socket. The CPU fits in only one correct orientation. DO NOT
force the CPU into the socket to prevent bending the pins and damaging the CPU!
1.6.1
Installing the CPU
To install a CPU:
1.
Locate the CPU socket on the motherboard.
M4A88T-M
M4A88T-M CPU Socket AM3
2.
Press the lever sideways to unlock the
socket, then lift it up to a 90°-100° angle.
Socket lever
Ensure that the socket lever is lifted up to a 90°-100° angle; otherwise, the CPU will not fit
in completely.
3.
Position the CPU above the socket such that the CPU
corner with the gold triangle matches the socket corner
with a small triangle.
4.
Carefully insert the CPU into the socket until it fits in place.
The CPU fits only in one correct orientation.
DO NOT force the CPU into the socket to
prevent bending the pins and damaging the
CPU!

1.6.2
Installing the heatsink and fan
Ensure that you use only AMD-certified heatsink and fan assembly.
To install the CPU heatsink and fan:
1.
Place the heatsink on top of the installed CPU, ensuring that the heatsink fits properly
on the retention module base.
• The retention module base is already installed on the motherboard upon purchase.
• You do not have to remove the retention module base when installing the CPU or
installing other motherboard components.
• If you purchased a separate CPU heatsink and fan assembly, ensure that a Thermal
Interface Material is properly applied to the CPU heatsink or CPU before you install the
heatsink and fan assembly.

Your boxed CPU heatsink and fan assembly should come with installation instructions for
the CPU, heatsink, and the retention mechanism. If the instructions in this section do not
match the CPU documentation, follow the latter.
2.
Attach one end of the retention bracket to the retention module base.

3.
Align the other end of the retention bracket to the retention module base. A clicking
sound denotes that the retention bracket is in place.
Ensure that the fan and heatsink assembly perfectly fits the retention mechanism module
base, otherwise you cannot snap the retention bracket in place.
4.
Push down the retention bracket lock on the retention mechanism to secure the
heatsink and fan to the module base.
5.
When the fan and heatsink assembly is in place, connect the CPU fan cable to the
connector on the motherboard labeled CPU_FAN.
DO NOT forget to connect the CPU fan connector! Hardware monitoring errors can occur if
you fail to plug this connector.

Overview

DIMM_A2
DIMM_B2
This motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules
(DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but
is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are
developed for better performance with less power consumption. The figure illustrates the
location of the DDR3 DIMM sockets:

Memory configurations
You may install 512MB, 1GB, 2GB, and 4GB unbuffered ECC and non-ECC DDR3 DIMMs
into the DIMM sockets.
• You may install varying memory sizes in Channel A and Channel B. The system maps
the total size of the lower-sized channel for the dual-channel configuration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• Always install DIMMs with the same CAS latency. For optimum compatibility, we
recommend that you obtain memory modules from the same vendor.
• Due to the memory address limitation on 32-bit Windows® OS, when you install 4GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3GB or less. For effective use of memory, we recommend that you do any of the
following:
-������������������������������������������������������������������������
Install a maximum of 3GB system memory if you are using a 32-bit Windows® OS.
-
Use a 64-bit �������
Windows® OS if you want to install 4GB or more memory on the motherboard.
• This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.
The motherboard supports up to 16GB memory modules on Windows® XP Professional x64
and Vista x64 editions. You may install a maximum of 4GB DIMMs on each slot.

3.
Remove the bracket opposite the slot that you intend to use. Keep the screw for later
use.
4.
Align the card connector with the slot and press firmly until the card is completely
seated on the slot.
5.
Secure the card to the chassis with the screw you removed earlier.
6.
Replace the system cover.
1.8.2
Configuring an expansion card
After installing the expansion card, configure it by adjusting the software settings.
1.
Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for
information on BIOS setup.
2.
Assign an IRQ to the card.
3.
Install the software drivers for the expansion card.
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.

Jumpers
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.

(Default)
Clear RTC
M4A88T-M Clear RTC RAM
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 reenter
data.
Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default
position. Removing the cap will cause system boot failure!
• If the steps above do not help, remove the onboard battery and move the jumper again
to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.
• You do not need to clear the RTC when the system hangs due to overclocking. For
system failure due to overclocking, use the CPU Parameter Recall (C.P.R) feature. Shut
down and reboot the system so the BIOS can automatically reset parameter settings to
default values.

Onboard switch
Onboard switches allow you to fine-tune performance when working on a bare or open-case
system. This is ideal for overclockers and gamers who continually change settings to
enhance system performance.
1.
MemOK! switch
Installing DIMMs that are incompaible with the motherboard may cause system boot
failure, and the DRAM_LED near the MemOK! switch lights continuously. Press and
hold the MemOK! switch until the DRAM_LED starts blinking to begin automatic
memory compatibility tuning for successful boot.
M4A88T-M
M4A88T-M MemOK! switch
• Refer to section 1.12 Onboard LEDs for the exact location of the DRAM_LED.
• The DRAM_LED also lights when the DIMM is not properly installed. Turn off the system
and reinstall the DIMM before using the MemOK! function.
• The MemOK! switch does not function under Windows® OS environment.
• During the tuning process, the system loads and tests failsafe memory settings. It takes
about 30 seconds for the system to test one set of failsafe settings. If the test fails,
the system reboots and test the next set of failsafe settings. The blinking speed of the
DRAM_LED increases, indicating different test processes.
• Due to memory tuning requirement, the system automatically reboots when each timing
set is tested. If the installed DIMMs still fail to boot after the whole tuning process, the
DRAM_LED lights continuously. Replace the DIMMs with ones recommended in the
Memory QVL (Qualified Vendors Lists) in this user manual or on the ASUS website at
www.asus.com.
• If you turn off the computer and replace DIMMs during the tuning process, the system
continues memory tuning after turning on the computer. To stop memory tuning, turn off
the computer and unplug the power cord for about 5–10 seconds.
• If your system fail to boot due to BIOS overclocking, press the MemOK! switch to boot
and load BIOS default settings. A messgae will appear during POST reminding you that
the BIOS has been restored to its default settings.
• We recommend that you download and update to the latest BIOS version from the
ASUS website at www.asus.com after using the MemOK! function.

2.2
BIOS setup program
This motherboard supports a programmable Serial Peripheral Interface (SPI) 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 SPI chip.
The SPI chip 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.
Entering BIOS Setup at startup
To enter BIOS Setup at startup:
• Press <Delete> during the Power-On Self Test (POST). If you do not press <Delete>,
POST continues with its routines.
Entering BIOS Setup after POST
To enter BIOS Setup after POST:
• Press <Ctrl>+<Alt>+<Del> simultaneously.
•
Press the reset button on the system chassis.
•
Press the power button to turn the system off then back on. Do this option only if you
failed to enter BIOS Setup using the first two options.
Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys to force
reset from a running operating system can cause damage to your data or system. We
recommend that you always shut down the system properly from the operating system.
• 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 Setup Defaults item under the Exit menu. See section 2.8 Exit Menu.
• The BIOS setup screens in this chapter are for reference only. They may not exactly
match what you see on your screen.
• Visit the ASUS website at www.asus.com to download the latest BIOS file for this
motherboard.
