Socket AM3 Micro ATX Platform

This MSI 890GXM-G65 motherboard uses the AMD 890GX chipset in a Micro ATX form factor. It accepts Socket AM3 processors including 64-bit AMD Phenom II CPUs. The board supports up to 16GB of dual-channel DDR3 memory at speeds from 1066 to 2133MHz with overclocking.

Installation Notes and Common Issues

The package includes the motherboard, a CMOS battery, one SATA cable and an I/O back panel. Two PCI Express x16 slots are present; the first runs at x16 speed and the second at x8 speed. When both slots are populated the bandwidth shifts to an x8/x8 configuration, which may limit multi-GPU scaling.

Sustained Load Behaviour

The Realtek 8111DL Gigabit LAN controller handles 10, 100 and 1000Mb/s traffic under continuous network load. Realtek ALC889 audio delivers 8-channel output compliant with Azalia 1.0 during extended playback. Two USB 3.0 ports on the rear panel maintain 3.0 signalling during prolonged transfers.

Questions about this item

How do I verify the board is running after first power-on?

Watch for the POST screen and listen for a single beep; the Realtek 8111 LAN LED should light when a cable is plugged in, and the onboard audio chip 889 will appear in Device Manager once drivers load

What ships in the box and what must I source myself?

The package contains the motherboard, one CMOS battery, one SATA cable and the rear I/O shield; you will need to buy a Socket AM3 processor, DDR3 memory modules, a power supply, storage drives and a case separately

Which memory speed should I choose for this board?

The board supports dual-channel DDR3 at 1066, 1333, 1600, 1800 and 2133 MHz; 1333 MHz runs at stock voltage while 1600 MHz and above require overclocking in the BIOS to reach the rated speed
