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.

Questions about this item

Do I need to provide my own AM4 processor and DDR4 memory for this board?

Yes, the board uses a Socket AM4 for RYZEN or 7th generation A-series/Athlon CPUs and accepts up to 32GB of dual-channel DDR4 at 1866, 2133, 2400, 2667, 2933 (OC) or 3200 (OC) MHz.

Will my existing SATA drives and PCIe 2.0 cards still connect?

The board provides four SATA III ports and two PCIe 2.0 x1 slots alongside the primary PCIe 3.0 x16 slot, so older SATA storage and legacy expansion cards remain usable.

How can I confirm the audio and network are active after assembly?

The Realtek ALC887 codec delivers 7.1 channel output and the Realtek 8111H Gigabit LAN appears in the OS network adapters list once drivers load.
