MSI 870A-G54
870A-G54: Socket AM3 / AMD 870 + SB850, 2010; revision-aware Socket motherboard specifications, CPU/BIOS qualification, board size, memory, expansion, storage and I/O.
IDENTIFICATION: Standard 870A-G54; do not confuse with 870A-G54 (FX). Confirm the exact silkscreen, revision and firmware on the physical board; near-name variants can use different BIOS files and connectors.
Specifications
| Catalog subcategory | AMD Socket platforms |
|---|---|
| Exact board / model | 870A-G54 — Standard 870A-G54; do not confuse with 870A-G54 (FX) |

| Rear I/O and compatibility | USB 3.0 and USB 2.0, Gigabit Ethernet, 8-channel audio, PS/2 and legacy audio/line connectors; discrete graphics required. This record is the non-FX 870A-G54, not the distinct 870A-G54 (FX). Use an AM3 CPU explicitly listed by MSI, the required BIOS and DDR3 memory; consult the manual for CrossFire and slot limits. |
Compatibility and revision notes
This record is the non-FX 870A-G54, not the distinct 870A-G54 (FX). Use an AM3 CPU explicitly listed by MSI, the required BIOS and DDR3 memory; consult the manual for CrossFire and slot limits.
Before installation, compare the physical board and revision against the manufacturer manual. Check socket condition, CPU power requirements, cooler/chassis clearance, DIMM population order, power connectors and any shared PCIe or SATA lanes. Update firmware only with the exact model’s supported procedure.
Preservation and repair
Record the PCB revision, BIOS identifier, serial/date code, installed CPU and memory, accessories, known faults, repairs and test conditions. Use ESD-safe handling and inspect for socket damage, corrosion, leaking capacitors and loose conductive hardware before power-up.
