GIGABYTE A520M DS3H DDR4 AMD Motherboard

The Gigabyte A520M DS3H is a Micro ATX motherboard built on the AMD A520 chipset and designed to pair with 3rd Generation AMD Ryzen processors — including Ryzen models with integrated Radeon Graphics — via the AM4 socket. Its compact 24.4 cm × 24.4 cm footprint makes it a practical choice for space-conscious desktop builds that still demand solid feature coverage. Memory flexibility is a strong point: four DDR4 DIMM slots accommodate up to 128 GB of system memory (with a maximum of 32 GB per DIMM). Native speeds run from DDR4-2133 up to DDR4-3200, and overclocked profiles can reach DDR4-4400 on standard Ryzen 3rd Gen CPUs or DDR4-4733 on APU variants. Dual-channel operation and XMP profile support are both included, as is compatibility with ECC unbuffered modules for workloads where memory reliability matters. For storage, an M.2 Socket 3 connector (M key, 2242/2260/2280) supports both PCIe 3.0 ×4 NVMe and SATA M.2 drives, while four SATA 6 Gb/s ports handle conventional drives with RAID 0, 1, and 10 support via the chipset. The single PCIe 3.0 ×16 slot handles discrete graphics, and two PCIe 3.0 ×1 slots provide room for additional expansion cards. Display output is handled through three rear-panel video ports — HDMI 2.1 (up to 4096×2160@60 Hz, HDCP 2.3, HDR), DisplayPort 1.4 (up to 5120×2880@60 Hz, HDCP 2.3, HDR), and DVI-D (up to 1920×1200@60 Hz) — supporting up to three simultaneous displays when using a Ryzen APU. Connectivity includes a Realtek Gigabit Ethernet (1000/100 Mbit) controller paired with the Realtek 8118 Gaming LAN Bandwidth Control Utility. Audio is handled by a Realtek ALC887 codec supporting High Definition Audio up to 7.1-channel output. On the rear panel sit four USB 3.2 Gen 1 Type-A ports and two USB 2.0 ports, complemented by internal headers for two additional USB 3.2 Gen 1 and two USB 2.0 connections. The 5+3 phase digital VRM with low RDS MOSFETs delivers stable power delivery to the CPU, and the board includes a dedicated 8-pin ATX 12 V connector. Smart Fan 5 provides hardware monitoring with multiple thermal sensor inputs, hybrid fan headers supporting both PWM and voltage-mode fans, and a Fan Stop feature. RGB Fusion 2.0 controls onboard RGB lighting alongside an addressable LED header (5 V, up to 300 LEDs) and a standard RGB LED header for ecosystem customisation. BIOS is AMI UEFI-based, stored on a 128 Mbit flash chip, and supports Q-Flash Plus — enabling BIOS updates without a CPU, memory, or graphics card installed. A TPM header (2×6 pin, compatible with the GC-TPM2.0_S module) is included for security applications. The board ships with a 3-year warranty. — Verified Specifications — • Socket: AMD AM4 | Chipset: AMD A520 • Form Factor: Micro ATX, 24.4 cm × 24.4 cm • Memory: 4 × DDR4 DIMM, up to 128 GB, DDR4-2133 to DDR4-3200 (native); up to DDR4-4400/4733 O.C.; ECC & XMP support • Storage: 1 × M.2 PCIe 3.0 ×4 / SATA (2242/2260/2280); 4 × SATA 6 Gb/s; RAID 0/1/10 • Expansion: 1 × PCIe 3.0 ×16; 2 × PCIe 3.0 ×1 • Display (APU): HDMI 2.1 (4K@60 Hz), DisplayPort 1.4 (5K@60 Hz), DVI-D (1920×1200@60 Hz); up to 3 displays • LAN: Realtek GbE (1000/100 Mbit) • Audio: Realtek ALC887, 7.1-channel HD Audio • USB (rear): 4 × USB 3.2 Gen 1, 2 × USB 2.0 • BIOS: AMI UEFI, 128 Mbit flash, Q-Flash Plus • Warranty: 3 Years
