Socket FM2/FM2+ micro-ATX platform

The board pairs the AMD A88X chipset with Socket FM2 and FM2+ support for A-Series and Athlon processors in a compact micro-ATX layout. Four DDR3 slots accept up to 32 GB of system memory running at 2400 MHz. It targets builders who want a small-footprint desktop foundation with modern connectivity.

Dual x16 slots and six SATA III ports

PCI_E1 delivers PCIe 3.0 x16 speed with FM2+ CPUs while PCI_E4 runs at PCIe 3.0 x8, giving room for a graphics card and a second add-in board. Two PCIe 2.0 x1 slots handle extra peripherals. Six SATA III connectors provide plenty of internal storage bandwidth without occupying expansion slots.

Killer E2205 LAN and Realtek ALC1150 audio

The onboard Killer E2205 Gigabit controller prioritises gaming traffic for lower latency during extended sessions. Realtek ALC1150 drives 7.1 channel high-fidelity output with S/PDIF support. USB 3.0 is supplied by both the A88X chipset and a VIA VL806 controller for sustained throughput across four rear and internal ports.

Questions about this item

Does the A88X chipset throttle the PCIe 3.0 x16 slot to x8 when the second x16 slot is populated?

PCI_E1 runs at PCIe 3.0 x16 and PCI_E4 at PCIe 3.0 x8 when a Socket FM2+ processor is installed; the chipset does not reduce the primary slot below x16.

How loud does the Killer E2205 LAN controller get under continuous network load?

The LAN controller is a passive component with no fan, so it adds no audible noise regardless of traffic volume.

Which DDR3 memory speeds are guaranteed to reach 2400 MHz without manual voltage changes?

The board supports DDR3 up to 2400 MHz; achieving that frequency depends on the memory modules' XMP profiles and the CPU's integrated memory controller.
