AMD Ryzen Processor Compatibility
The AM4 socket supports selected AMD Ryzen 5000 Series, Ryzen 5000 G-Series, Ryzen 4000 G-Series, Ryzen 3000 Series, and Ryzen 3000 G-Series processors. The motherboard uses a 4+3-phase pure digital VRM design with low RDS(on) MOSFETs. Check GIGABYTE's CPU support list for the exact processor and BIOS requirements before installation.
DDR4 Memory Support
Two DDR4 DIMM slots support up to 64GB of system memory in a dual-channel configuration. The board supports memory speeds up to DDR4 3200 MT/s as standard, with higher frequencies available through supported overclocking profiles. XMP memory modules are also supported.
M.2 and SATA Storage
The A520M S2H includes one M.2 connector for compatible 2242, 2260, and 2280 SATA or PCIe 3.0 x4/x2 SSDs. Four SATA 6Gb/s connectors provide additional storage options. Supported SATA RAID configurations include RAID 0, RAID 1, and RAID 10.
Expansion and Display Connectivity
The motherboard provides one PCIe 3.0 x16 slot for a compatible graphics card and two PCIe 3.0 x1 slots for additional expansion cards. Rear display connections include HDMI, DVI-D, and D-Sub. These motherboard display outputs require a compatible Ryzen processor with integrated Radeon graphics.
Networking and Audio
A Realtek Gigabit Ethernet controller provides wired network connectivity with GIGABYTE Gaming LAN bandwidth management. The onboard Realtek audio codec supports high-definition audio and multi-channel configurations, including 7.1-channel audio with the appropriate software configuration.
Cooling, Lighting and BIOS Features
GIGABYTE Smart Fan 5 provides multiple temperature sensors, hybrid fan headers, and Fan Stop functionality. RGB Fusion 2.0 supports compatible RGB and addressable LED lighting components. Q-Flash Plus allows BIOS updates without installing the CPU, memory, or graphics card.
