Micro ATX board for AMD A-Series and E2-Series APUs

The ASUS F1A55-M LX3 R2.0/CM1735/DP_MB is a Micro ATX motherboard built on the AMD A55 Hudson D2 chipset. It accepts A-Series and E2-Series processors in an AM1 socket and provides dual-channel DDR3 memory support up to 32 GB. Onboard graphics use the ATI Radeon HD 6000 engine with a single D-Sub video output.

Suited for basic desktop builds

This board fits budget office PCs, simple home desktops or replacement of older AM1 platforms where integrated graphics and legacy I/O are required. It is not intended for modern gaming rigs or high-performance workstations that need current CPU architectures, faster memory standards or PCIe 3.0 and 4.0 expansion bandwidth.

DDR3 1866 dual-channel memory ceiling of 32 GB

Two 240-pin slots accept DDR3 modules at 1866, 1600, 1333 and 1066 speeds in dual-channel mode, capping total capacity at 32 GB. This memory specification decides whether the board can meet the capacity and bandwidth needs of the intended workload.

Questions about this item

How much heat and noise should I expect from the A55 chipset and ATI Radeon HD 6000 graphics when the board runs all day?

The AMD A55 Hudson D2 chipset and integrated ATI Radeon HD 6000 graphics are low-power components that produce minimal heat; a standard case fan and the APU cooler are usually enough to keep temperatures and noise low during continuous operation.

Which processor and memory must I already have to use this Micro ATX board?

You need an AMD A-Series or E2-Series APU that fits the AM1 socket, plus up to two DDR3 DIMMs running at 1866, 1600, 1333 or 1066 MHz for a maximum of 32 GB in dual-channel mode.

Will my older PCI add-in card and PS/2 keyboard still work with this motherboard?

Yes, the board provides one legacy PCI slot and two PS/2 ports, so older PCI expansion cards and PS/2 keyboards or mice connect directly without adapters.
