Socket FM1 platform for AMD Llano APUs
This micro-ATX motherboard uses the AMD A55 chipset and accepts Socket FM1 processors. It supports dual-channel DDR3 memory at 1600, 1333 and 1066 MHz up to 16 GB. One PCI Express x16 slot, two PCIe x1 slots and two legacy PCI slots provide expansion options. Six SATA II ports and a Realtek Gigabit LAN controller handle storage and networking.
Suited to budget desktop builds and repair projects
The board fits users who need a low-cost FM1 foundation for office work, media playback or legacy hardware compatibility. Enthusiasts requiring newer CPU sockets, faster memory standards or modern high-speed storage interfaces should consider a different platform. The micro-ATX form factor also limits space for large multi-GPU configurations.
Basic accessory kit enables immediate assembly
Included are a CMOS battery, one SATA cable and a chassis I/O back panel for case installation. No driver disc, additional cables or Wi-Fi antenna are supplied, so builders must source any extra SATA leads, operating-system media or wireless hardware separately. The minimal bundle keeps the package light but requires a few extra parts to complete a system.

Questions sur cet article
Do I need to supply my own AMD Llano APU for the Socket FM1 on this MSI A55-S51?
Yes, the board requires an AMD Llano APU that fits the Socket FM1; the CPU is not included.
Will my existing PCI expansion cards fit the two PCI slots and the two PCIE x1 slots on this motherboard?
The board provides two legacy PCI slots and two PCI Express x1 slots, so most older PCI cards and modern x1 cards will install.
How can I confirm the dual-channel DDR3 memory is running at 1600MHz after I install two modules?
Enter the BIOS or use a system-information tool; it will report the memory operating in dual-channel mode at 1600MHz.
