Socket FM2/FM2+ micro-ATX board

The MSI A88XM-P33 is a micro-ATX motherboard built around the AMD A88X chipset for Socket FM2 and FM2+ APUs. It targets budget-conscious builders who need a compact platform for home or office systems. Dual-channel DDR3 support up to 2133 MHz and a 32 GB memory ceiling cover mainstream workloads. A single PCIe 3.0 x16 slot handles a discrete graphics card.

Suits APU builds, not high-core CPUs

This board fits users pairing an A-Series or Athlon processor with integrated graphics for everyday computing, media playback or light gaming. The four SATA III ports and eight USB 2.0 ports give plenty of storage and peripheral connectivity. Realtek 8.1-channel audio and gigabit LAN cover basic multimedia needs. Enthusiasts chasing high core counts, overclocking headroom or modern memory standards should look elsewhere.

Dual-channel DDR3 up to 2133 MHz

The memory controller officially supports DDR3 at 2133, 1866, 1600 and 1333 MHz in dual-channel mode with a 32 GB maximum. Buyers must confirm their APU and memory kit match these speeds to avoid downclocking. No other memory type is supported.

Questions about this item

Which AMD processor socket does the MSI A88XM-P33 require for the CPU I already own?

The board accepts Socket FM2 and FM2+ AMD A-Series or Athlon processors, so your existing CPU must use one of those two sockets.

Will my current DDR3 memory kits run at their rated speed on the A88XM-P33?

The motherboard supports dual-channel DDR3 at 2133, 1866, 1600 and 1333 MHz, so modules rated for any of those frequencies will operate at their specified speed.

How can I verify the Realtek RTL8111G LAN controller is functioning after I build the system?

Connect an Ethernet cable; the OS should detect a 10, 100 or 1000 Mb/s link and show the RTL8111G adapter in Device Manager with an active connection status.
