Gigabyte A520M DS3H (AM4/AMD A520/mATX/Budget/Four DIMM Slots) Review
The A520M DS3H is Gigabyte's budget micro-ATX AM4 board, notable for including four DDR4 DIMM slots at a price point where many competing A520 boards only offer two.
Gigabyte's own listing describes a "5+3 Phases Digital PWM" design for this board, adequate for non-X3D Ryzen chips at stock clocks since the A520 chipset locks CPU overclocking. Four DDR4 DIMM slots run dual-channel, giving builders more memory expansion room than many other budget A520 boards. Expansion includes a single PCIe 3.0 x16 slot for the GPU. Storage covers a single PCIe 3.0 x4 M.2 slot for NVMe drives, alongside multiple SATA ports. An onboard Gigabit LAN controller handles wired networking; this board does not include built-in WiFi. Against the ASUS Prime A520M-K in this batch, the A520M DS3H's four DIMM slots make it the clearly better pick for builders who want to run a full four-stick memory kit rather than being limited to two modules.
