AM4 Micro ATX Platform
The ASRock A520M-HDV is an AMD A520 motherboard built for the AM4 socket. It targets builders who want a compact foundation for Ryzen 3000 and 4000 series processors. The board excludes Ryzen 5 3400G and Ryzen 3 3200G from its supported CPU list. Dual channel DDR4 memory tops out at 64 GB across two slots.
Upgrade Path From Older AM4 Boards
Moving from an A320 or first generation Ryzen board adds native PCIe 3.0 x4 M.2 bandwidth and broader memory frequency headroom. The jump is worth it when you need NVMe boot speeds or plan to run DDR4 above 3200 MT/s on a Matisse or Renoir CPU.
Build Integration Essentials
One full length PCIe 3.0 x16 slot handles a discrete GPU while a single x1 slot remains for add in cards. Four SATA 6.0 Gb/s ports and one Ultra M.2 socket with 2242, 2260 and 2280 support cover storage. Realtek ALC887 7.1 channel audio and RTL8111H 1 Gbps LAN handle I/O without extra cards.

Questions about this item
Will the 288-pin DDR4 slots fit inside a standard Micro ATX case?
Yes, the Micro ATX form factor matches standard Micro ATX mounting holes, so the board fits any case designed for that size.
Which power connectors must be attached before the first boot?
Connect the 24-pin ATX cable and the 8-pin CPU power cable; forgetting the 8-pin connector is the most common reason the system will not post.
How often should the Realtek ALC887 audio capacitors be checked for leakage?
Solid capacitors on this board are rated for long life; visual inspection once a year is sufficient unless you hear distortion.
