Chapter 1 Product introduction 1.1 Welcome! Thank you for buying an ASUS® M5A88-M EVO 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+ / 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 out connector at the back panel This motherboard provides convenient connectivity to external home theater audio systems via the optical S/PDIF (SONY-PHILIPS Digital Interface) out connector at the back panel. The S/PDIF transfers digital audio without converting it to analog format and keeps the best signal quality.
MemOK! MemOK! quickly 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. Fan Xpert ASUS Fan Xpert intelligently allows you to adjust the CPU and chassis fan speeds according to different ambient temperatures caused by different climate conditions in different geographic regions and your PC’s loading.
1.4 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. • Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, to avoid damaging them due to static electricity. • Hold components by the edges to avoid touching the ICs on them.
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 FX™ / 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.
