Chapter 1 Product introduction 1.1 Welcome! Thank you for buying an ASUS® M4A88TD-M motherboard! The motherboard delivers a host of new features and latest technologies, making it another standout in the long line of ASUS quality motherboards! Before you start installing the motherboard, and hardware devices on it, check the items in your package with the list below. 1.2 Package contents Check your motherboard package for the following items.
AMD® 880G Chipset The AMD® 880G Chipset is designed to support up to 5200MT/s HyperTransport™ 3.0 (HT 3.0) interface speed and PCI Express 2.0 x16 graphics. It is optimized with AMD’s latest AM3 multi-core CPUs to provide excellent system performance and overclocking capabilities. DDR3 2000(O.C.)/1333/1066 support This motherboard supports DDR3 memory that features data transfer rates of 2000(O.C.
S/PDIF digital sound ready This motherboard provides convenient connectivity to external home theater audio systems via the coaxial and optical S/PDIF_OUT (SONYPHILIPS Digital Interface) interface. The S/PDIF transfers digital audio without converting it to analog format and keeps the best signal quality. 1.3.2 Innovative ASUS features 1 2 Core Unlocker ASUS Core Unlocker simplifies the activation of a latent AMD® CPU— with just a simple switch.
ASUS Express Gate ASUS Express Gate is an ASUS exclusive OS that provides you with quick access to the Internet and key applications before entering Windows® OS. • ASUS Express Gate supports installation on SATA HDDs, USB HDDs and flash drives with at least 1.2GB free disk space. When installing it on USB HDDs or flash drives, connect the drives to the motherboard USB port before turning on the computer. • The actual boot time depends on the system configuration.
Precision Tweaker 2 Allows you to fine-tune the VCore / VDDNB voltage in 0.003125V steps and DRAM voltage in 0.015V steps to achieve the most precise setting for the ultimate overclocking configuration. C.P.R. (CPU Parameter Recall) The BIOS C.P.R. feature automatically restores the CPU default settings when the system hangs due to overclocking failure. C.P.R. eliminates the need to open the system chassis and clear the RTC data.
1.5 Motherboard overview 1.5.1 Placement direction 1.5.2 Screw holes When installing the motherboard, ensure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis as indicated in the image below. Place eight screws into the holes indicated by circles to secure the motherboard to the chassis. DO NOT overtighten the screws! Doing so can damage the motherboard. Place this side towards the rear of the chassis.

1.6 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. 2.
5. When the CPU is in place, push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked. 6. Install a CPU heatsink and fan following the instructions that comes with the heatsink package. You can also refer to section 1.6.2 Installing heatsink and fan for instructions. 7. Connect the CPU fan cable to the CPU_FAN connector on the motherboard.
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.
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.
1.7.2 Memory configurations (AM3, 2-channel) 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. • We recommend that you install the memory modules from the blue slots for better overclocking capability.

DIMM notch 1 1 DIMM slot key Unlocked retaining clip A DIMM is keyed with a notch so that it fits in only one direction.
1.8 Expansion slots In the future, you may need to install expansion cards. The following sub‑sections describe the slots and the expansion cards that they support. Unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. 1.8.1 Installing an expansion card To install an expansion card: 1.
1.9 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. 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.
1.10 Connectors 1.10.1 Rear panel ports 1. PS/2 Keyboard / Mouse Combo port (purple). This port is for a PS/2 keyboard or PS/2 mouse. 2. Optical S/PDIF_OUT port. This port connects to an external audio output device via an optical S/PDIF cable. 3. VGA port. This 15-pin port is for a VGA monitor or other VGA-compatible devices. 4. LAN (RJ-45) port. This port allows Gigabit connection to a Local Area Network (LAN) through a network hub.

Connect the chassis power LED cable to this connector.
7. USB connectors (10-1 pin USB78, USB910, USB1112, USB1314) These connectors are for USB 2.0 ports. Connect the USB module cable to any of these connectors, then install the module to a slot opening at the back of the system chassis. These USB connectors comply with USB 2.0 specification that supports up to 480Mbps connection speed. Never connect a 1394 cable to the USB connectors. Doing so will damage the motherboard! The USB 2.0 module is purchased separately. 8.
9. Digital audio connector (4-1 pin SPDIF_OUT) This connector is for an additional Sony/Philips Digital Interface (S/PDIF) port. Ensure that the audio device of Sound playback is Realtek High Definition Audio (the name may be different based on the OS). Go to Start > Control Panel > Sounds and Audio Devices > Sound Playback to configure the setting. The S/PDIF module is purchased separately. 10.
1.11 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. Core Unlocker switch This switch allows you to unlock the extra cores of your CPU. To ensure system performance, turn the switch setting to Enable when the system is powered off. • The O2LED1 LED near the Core Unlocker switch lights when the switch setting is turned to Enable.
2. MemOK! switch Installing DIMMs that are incompatible 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. • 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.
1.12 1. 2. 3. Onboard LEDs Standby Power LED The motherboard comes with a standby power LED that lights up to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you should shut down the system and unplug the power cable before removing or plugging in any motherboard component. The illustration below shows the location of the onboard LED. DRAM LED DRAM LED checks the DRAM in sequence during motherboard booting process.
