Socket FM2+ AMD A55 motherboard

The MSI A55-G41 PC Mate is an ATX board built around the AMD A55 chipset for Socket FM2+ Athlon and A-Series processors. It targets system builders assembling a basic desktop or upgrading an older platform that still relies on DDR3 memory. The board delivers standard connectivity and expansion for everyday computing tasks.

Dual-channel DDR3 and PCIe lane limits

Memory runs in dual-channel mode at 1333, 1600, 1866 or 2133 MHz with OC support up to a total of 64 GB. The primary PCIe x16 slot operates at 3.0 speed only when the installed processor supports the specification; the second x16 slot is wired for 2.0 x4. Six SATA 2.0 ports provide storage connections, while Realtek ALC887 audio and RTL8111E Gigabit LAN handle sound and networking.

Straightforward ATX installation with legacy quirks

The board fits any standard ATX chassis and uses a conventional 24-pin plus 4-pin power layout, so assembly follows the usual routine. Builders should verify that their chosen FM2+ CPU actually enables PCIe 3.0 on the top slot, otherwise the primary graphics link will fall back to 2.0. The package includes only the board, a CMOS battery, one SATA cable and the I/O shield.

Perguntas sobre este artigo

Should I pick the 1333, 1600, 1866 or 2133 MHz DDR3 kit for this board?

The board runs dual-channel DDR3 at 1333, 1600 and 1866 MHz natively; 2133 MHz is only reachable by overclocking, so choose a kit rated for the highest native speed you want guaranteed stability at.

What does the 64 GB maximum memory figure mean once the board is in a real machine?

You can install up to 64 GB of DDR3 across the four slots in dual-channel mode, giving the full capacity the chipset allows for large workloads or many browser tabs.

Which PCIe standard do the two x16 slots actually run at and what does that cap?

The primary PCI_E2 slot runs at PCIe 3.0 x16 with a compatible FM2+ processor, while PCI_E4 is limited to PCIe 2.0 x4, so graphics bandwidth tops out at the 3.0 x16 ceiling on the main slot.
