AM4 Socket for Ryzen 5000 and 3000 Series

This motherboard uses the AMD A520 chipset and AM4 socket to support Ryzen 5000 Series, 5000 G-Series, 4000 G-Series and 3000 Series processors. It targets builders who want a straightforward platform for mainstream desktop CPUs without overclocking headroom. The 5+3 phase digital VRM uses low RDS(on) MOSFETs to deliver stable power for daily workloads.

128GB DDR4 Dual Channel and Single M.2

Four 288-pin slots accept unbuffered DDR4 up to 128GB in dual-channel mode with speeds ranging from 2133 to 4733(OC). A single M.2 socket 3 M-key slot handles 2242, 2260 and 2280 drives with both SATA and PCIe 3.0 x4 or x2 modes. Four SATA 6Gb/s ports add bulk storage and support RAID 0, 1 and 10.

Intel Wi-Fi 802.11ac, Bluetooth 4.2 and 8118 LAN

The rear I/O includes HDMI, DVI-D and DisplayPort for multi-monitor setups driven by APUs, plus four USB 3.2 Gen 1 ports, two USB 2.0 ports, PS/2, three audio jacks for 7.1-channel output, two SMA antenna connectors and a Realtek 8118 Gigabit LAN port. Onboard Intel wireless provides 802.11ac and Bluetooth 4.2. RGB Fusion 2.0 headers support addressable and standard LED strips while Smart Fan 5 offers hybrid headers with fan stop.

Questions about this item

Will my existing DDR4 memory rated at 3200 MHz run at its rated speed on the A520M DS3H AC?

The board supports DDR4 up to 3200 MHz natively and up to 4733 MHz with overclocking using 3rd Gen Ryzen processors, so 3200 MHz modules will operate at their rated speed without overclocking.

How can I verify that the single M.2 slot is running at PCIe 3.0 x4 after I install an NVMe drive?

Check the BIOS or operating-system device manager; the slot is wired for PCIe 3.0 x4 and will report that link width when a compatible NVMe SSD is installed.

Does the package include the two SMA antennas needed for the 802.11 ac Wi-Fi and Bluetooth 4.2, or must I buy them separately?

The supplier description confirms an antenna is included, so the two SMA antennas required for Wi-Fi and Bluetooth are in the box.
