Socket FM1 AMD A55 board

The ASUS F1A55-M LX3 PLUS R2.0 is a Micro ATX motherboard built for Socket FM1 processors using the AMD A55 chipset. It supports up to 32GB of DDR3 memory across the board's slots. The form factor suits compact builds that need standard desktop expansion.

Included back panel and battery

A chassis I/O back panel ships in the box so the rear ports align correctly with the case cut-out. One SATA cable is provided for connecting a single drive without an extra purchase. A fresh CMOS battery is also included to keep BIOS settings after power loss.

Straightforward Micro ATX install

The board follows the Micro ATX mounting pattern used by most modern cases. Align the standoffs, secure the screws, attach the supplied I/O panel, then connect the SATA cable and front-panel headers. Missing standoffs or an incorrect panel are the most common issues.

Questions about this item

Will the CMOS battery supplied with the ASUS F1A55-M LX3 PLUS R2.0 need replacing after a few years?

The board ships with a CMOS battery; like any coin cell it will eventually lose charge and should be swapped when the system clock drifts or BIOS settings reset.

What memory ceiling does the AMD A55 chipset on this Socket FM1 board enforce?

The chipset and board design limit total DDR3 capacity to 32 GB across the available slots.

How much heat or fan noise should I expect when the ASUS F1A55-M LX3 PLUS R2.0 runs continuously?

The Micro ATX layout uses passive chipset cooling, so sustained loads produce only modest warmth and virtually no extra noise beyond the CPU cooler.
