Socket AM3 AMD 870 board

The MSI 870S-G54 is an ATX motherboard built on the AMD 870 chipset for Socket AM3 processors. It targets builders assembling or refreshing systems around 64-bit Phenom II CPUs. The board delivers core platform features without onboard video, leaving graphics choice entirely to the add-in card.

16GB dual-channel DDR3 headroom

Four DIMM slots support dual-channel DDR3 at 800, 1066, 1600, 1800 and 2000 MHz, the last three achieved through overclocking. Maximum capacity is 16GB, giving comfortable headroom for period workloads while the 2000 MHz ceiling marks the practical limit for memory speed on this platform.

ATX layout with legacy and modern I/O

The board provides two PCI Express x16 slots, one x1 slot and three 3.3V/5V PCI slots for older expansion cards. Six SATA 6Gbps ports handle storage, while a Realtek ALC892 codec drives 8-channel audio and a Realtek 8111DL controller supplies Gigabit LAN. Eight USB 2.0 ports on the rear panel cover everyday peripherals.

Questions about this item

Will my existing PCI cards still work with the three 3.3v/5v PCI slots on this board?

Yes, the three PCI slots accept 3.3v and 5v cards so legacy expansion cards can be used alongside the newer PCI Express slots.

How can I verify the Realtek ALC892 audio is functioning after I build the system?

Check Device Manager for the Realtek High Definition Audio device and play a test sound through the 8-channel output to confirm the codec is detected and working.

Which accessories come in the box and what must I source separately for a complete build?

The package includes the motherboard, one CMOS battery, one SATA cable and the chassis I/O back panel; you will need to buy a CPU, DDR3 memory, storage drives, power supply and case separately.
