GIGABYTE B850M DS3H AMD Motherboard

The GIGABYTE B850M DS3H is a Micro ATX motherboard built on the AMD B850 chipset and AMD Socket AM5 platform, designed to support AMD Ryzen 9000, 8000, and 7000 series processors. Its compact 24.4 cm x 24.4 cm footprint makes it an efficient choice for space-conscious builds without sacrificing feature depth. Memory support is a standout characteristic of this board. Four DDR5 DIMM slots operate in dual-channel configuration and accept up to 256 GB of system memory, with a maximum single DIMM capacity of 64 GB. Supported speeds span from 4400 MT/s all the way to 8200 MT/s in overclocked mode. The board is compatible with AMD EXPO and XMP memory profiles, enabling straightforward memory tuning from within the BIOS. For graphics, the primary PCI Express x16 slot (PCIEX16) runs at PCIe 5.0 x16 bandwidth with Ryzen 9000 and 7000 series CPUs. A secondary chipset-connected slot supports PCIe 3.0 at x4. Storage options include two M.2 Socket 3 connectors — the first (M2A_CPU) supports PCIe 5.0 x4 NVMe SSDs on Ryzen 9000/7000 — alongside four SATA 6 Gb/s ports. NVMe RAID configurations (0, 1, 5, 10) and SATA RAID (0, 1, 10) are supported, with RAID 5 exclusive to Ryzen 9000 processors. Display output comes via one HDMI 2.1 port (up to 4096×2160 @ 60 Hz) and two DisplayPort 1.4 outputs (up to 3840×2160 @ 144 Hz), supporting up to three simultaneous displays when a compatible integrated graphics CPU is installed. Networking is handled by a Realtek Gigabit Ethernet controller. Audio uses a Realtek High Definition Audio CODEC supporting up to 7.1-channel output. USB connectivity on the rear panel includes one USB 3.2 Gen 2 Type-C, one USB 3.2 Gen 2 Type-A, two USB 3.2 Gen 1 Type-A, and four USB 2.0 ports. Internal headers add further USB 3.2 Gen 2 Type-C, Gen 1, and USB 2.0 expansion. The board features GIGABYTE’s Smart Fan 6 thermal management system, with fan headers supporting PWM and DC modes at up to 24 W (12 V × 2 A) per header, complete fan-stop capability, and customisable fan curves via a seven-point BIOS interface. Three addressable RGB Gen2 headers and one standard RGB header provide lighting flexibility managed through GIGABYTE Control Center. GIGABYTE’s X3D Turbo Mode BIOS feature is included, delivering optimisation parameters for Ryzen X3D and non-X3D processors. The AORUS AI SNATCH feature offers one-click CPU and DDR5 memory acceleration. Q-Flash Plus enables BIOS updates without a CPU or RAM installed. The BIOS is AMI UEFI-based, stored in a 256 Mbit flash chip.
