Socket AM3+ DDR3 platform
The MSI 870S-G46(FX) is an ATX motherboard built around the AMD 870 chipset for Socket AM3+ processors. It accepts 64-bit AMD FX, Phenom II, Athlon II and Sempron CPUs and provides four DDR3 slots supporting dual-channel operation up to 32GB at 1600MHz via overclocking. The board targets users maintaining or upgrading existing AM3+ systems.
Suited for AM3+ upgrades, not new builds
This board fits builders replacing a failed motherboard in a working AM3+ machine or assembling a budget system from spare DDR3 memory and a compatible CPU. It offers six SATA ports, two PCI Express x16 slots — one at x16 and one at x4 — plus three legacy PCI slots for older expansion cards. Users needing USB 3.0, M.2 slots or modern CPU sockets should select a current-platform board instead.
32GB DDR3 ceiling
The maximum supported memory is 32GB across four DDR3 slots running at 1600, 1333, 1066 or 800MHz. That limit is fixed by the chipset and cannot be exceeded, so any build requiring more RAM must move to a newer platform.
