AM4 Mini-ITX board for compact Ryzen builds

This ASRock motherboard fits the Mini-ITX form factor and uses the AMD A320 chipset with an AM4 socket. It accepts AMD A-Series APUs (Bristol Ridge) and Ryzen CPUs from the Summit Ridge, Raven Ridge and Pinnacle Ridge families. The board targets small-form-factor systems that need a full desktop socket in a reduced footprint.

PCIe 3.0 x16 slot and Ultra M.2 share CPU lanes

The single PCI Express 3.0 x16 slot runs at x16 with Summit Ridge or Pinnacle Ridge CPUs but drops to x8 with 7th Gen A-Series APUs or Raven Ridge CPUs. The Ultra M.2 socket delivers up to Gen3 x4 (32Gb/s) with Ryzen CPUs and Gen3 x2 (16Gb/s) with A-Series APUs. Four SATA3 6.0Gb/s ports support RAID 0, 1 and 10 alongside the M.2 slot.

Dual-channel DDR4 tops out at 32 GB

Two 288-pin slots support un-buffered DDR4 up to 3466+(OC) with Pinnacle Ridge, 3200(OC) with Summit Ridge or Raven Ridge and 2400 with 7th Gen A-Series APUs. Maximum capacity is 32 GB across both slots. ECC and non-ECC modules are accepted depending on the installed CPU.

Questions about this item

Which CPU should I pair with this board to reach the 3466 MHz DDR4 overclock rating?

Ryzen Pinnacle Ridge or Summit Ridge CPUs enable the DDR4 3466+(OC) memory speed on this A320M-ITX board.

What does the 32Gb/s M.2 figure mean once a drive is installed?

With a Ryzen Summit Ridge, Raven Ridge or Pinnacle Ridge CPU the Ultra M.2 socket runs at PCIe Gen3 x4 giving up to 32Gb/s throughput.

What does the PCIe 3.0 x16 slot cap at when I use a Raven Ridge processor?

With a Raven Ridge CPU the single PCIe 3.0 x16 slot operates in x8 mode, halving the theoretical bandwidth.
