Socket FM2 AMD A55 board

This micro-ATX motherboard uses the AMD A55 chipset and a Socket FM2 CPU interface. It is built for AMD A10, A8, A6 and A4 series processors. The board fits compact cases and supports up to 16GB of system memory.

Dual-channel DDR3 up to 2133

Memory runs in dual-channel mode at 1066, 1333, 1600, 1866 or 2133MHz with overclocking. The 16GB maximum capacity is the key figure to match against your planned RAM kit. Four DIMM slots are provided for this limit.

Simple drop-in with basic I/O

The board mounts with standard micro-ATX screw holes and ships with a rear I/O shield, one SATA cable and a CMOS battery. Align the shield before seating the board. Connect the 24-pin and 4-pin power headers, then add drives to the six SATA ports.
