MSI A320M GRENADE AMD motherboard

Socket AM4 foundation

The MSI A320M GRENADE is a micro ATX motherboard built around the AMD A320 chipset for Socket AM4 processors. It accepts RYZEN series CPUs as well as 7th generation A-series and Athlon chips. Dual-channel DDR4 memory runs at speeds up to 3200 MHz when overclocked, with a 32GB maximum capacity. A single PCIe 3.0 x16 slot and two PCIe 2.0 x1 slots handle expansion.

Entry builders and basic upgrades

This board suits budget-conscious builders assembling a home-office or light-gaming system with a single graphics card. Four SATA III ports and one M.2 interface provide enough storage connections for a modest SSD and hard-drive combination. Realtek ALC887 audio delivers 7.1 channel output and the 8111H Gigabit LAN handles wired networking. Builders who need multiple GPUs, extensive overclocking headroom or more than two high-speed USB ports should look elsewhere.

PCIe 3.0 x16 single-slot layout

The defining specification is the single PCIe 3.0 x16 slot that operates at x16 with RYZEN processors and drops to x8 with 7th generation A-series or Athlon CPUs. This lane allocation fixes the graphics expansion ceiling for the platform. If your build requires a second x16-width slot or full x16 bandwidth on an A-series processor, this motherboard will not meet that requirement.
