AMD AM5 Processor Platform
The AM5 socket supports selected AMD Ryzen 7000, Ryzen 8000, and Ryzen 9000 Series processors. A 5+2+2-phase digital VRM design provides CPU power delivery. Processor compatibility and required BIOS versions should be checked against GIGABYTE's CPU support documentation before installation.
DDR5 Dual-Channel Memory
Two DDR5 DIMM slots support up to 128GB of system memory in a dual-channel configuration. Supported memory speeds include standard DDR5 rates and overclocked configurations up to 6400 MT/s, depending on the motherboard revision, processor, and memory kit. AMD EXPO and Intel XMP memory profiles are supported.
PCIe Expansion and Storage
The motherboard provides one PCIe x16 slot for a compatible graphics card and one PCIe 3.0 x1 slot for an additional expansion card. The x16 slot operates at PCIe 4.0, with available bandwidth depending on the installed processor.
One M.2 connector supports compatible PCIe 4.0 x4/x2 SSDs. Four SATA 6Gb/s connectors provide additional storage connectivity. RAID 0, RAID 1, and RAID 10 configurations are supported for compatible NVMe and SATA storage devices.
Display Connectivity
Rear display connections include DisplayPort 1.4, HDMI 2.1, and D-Sub. DisplayPort supports resolutions up to 3840 x 2160 at 144Hz, HDMI supports up to 4096 x 2160 at 60Hz, and D-Sub supports up to 1920 x 1200 at 60Hz. Actual display capabilities depend on the processor's integrated graphics.
Networking and Audio
A Realtek Gigabit Ethernet controller provides wired network connectivity at supported 10/100/1000 Mbps speeds. The onboard Realtek audio codec supports high-definition audio and multi-channel configurations, including 7.1-channel audio with the appropriate software settings.
Cooling, Lighting and BIOS Features
GIGABYTE Smart Fan 6 provides temperature monitoring, hybrid fan headers, and Fan Stop functionality. RGB Fusion supports compatible RGB and addressable LED components through the onboard lighting headers. Q-Flash Plus allows BIOS updates without installing the CPU, memory, or graphics card.
