Chapter 1 Product introduction 1.1 Welcome! Thank you for buying an ASUS® M4A88T-V EVO Series 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.
DDR3 2000(O.C.)/1333/1066 support This motherboard supports DDR3 memory that features data transfer rates of 2000(O.C.)/1333/1066 MHz to meet the higher bandwidth requirements of the latest 3D graphics, multimedia, and Internet applications. The dual-channel DDR3 architecture enlarges the bandwidth of your system memory to boost system performance. SidePort Memory This motherboard features SidePort Memory, an individual onboard DDR3 memory serving as memory buffer for integrated graphics.
8-channel high definition audio The onboard 8-channel HD audio (High Definition Audio, previously codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio jack-sensing feature, retasking functions, and multi-streaming technology. ATI CrossFireX™ Technology ATI’s CrossFireX™ boosts image quality along with rendering speed, eliminating the need to scale down screen resolution to get high quality images. CrossFireX™ allows higher antialiasing, anisotropic filtering, shading, and texture settings.
Turbo Unlocker Turbo Unlocker is the next evolution of an exclusive ASUS performance boost feature. One click in the TurboV EVO interface and Turbo Unlocker automatically and dynamically adjusts AMD 6-CORE and Black Edition processor frequencies to speed up performance based on system load. Turbo Unlocker gets you in touch with more power when you need it. Core Unlocker ASUS Core Unlocker simplifies the activation of a latent AMD® CPU— with just a simple switch.
ASUS EPU ASUS EPU is a unique power saving technology that detects the current system loadings and adjusts the power consumption in real time. MemOK! MemOK! guickly ensures memory boot compatibility. This remarkable memory rescue tool requires a mere push of the button to patch memory issues. MemOK! determines failsafe settings and dramatically improves your system boot success. Get your system up and running in no time.
Precision Tweaker 2 Allows you to fine-tune the VCore voltage in 0.003125V steps, VChipset (VDDNB) voltage in 0.01V 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 nine 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.
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 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.

1.7.3 Installing a DIMM Unplug the power supply before adding or removing DIMMs or other system components. Failure to do so can cause severe damage to both the motherboard and the components. 2 1. Press the retaining clips outward to unlock a DIMM socket. 2. Align a DIMM on the socket such that the notch on the DIMM matches the DIMM slot key on the socket. 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.
VGA configuration PCI Express operating mode PCIe x16_1 PCIe x16_2 Single VGA/PCIe card x16 (Recommended for single VGA card) N/A Dual VGA/PCIe card x16 x4 • In single VGA card mode, use first the PCIe 2.0 x16_1 slot (blue) for a PCI Express x16 graphics card to get better performance. • For M4A88T-V EVO/USB3, the PCIe x1 slot shares the bandwidth with the PCIe x16_2 slot.
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.
