GIGABYTE B650M S2H DDR5 AMD Motherboard

The Gigabyte B650M S2H is a Micro ATX motherboard built on the AMD B650 chipset, designed for the AM5 socket and compatible with AMD Ryzen 7000 and Ryzen 8000 series processors. Its compact 23.0 cm × 22.5 cm footprint makes it well suited to space-efficient desktop builds without sacrificing platform capability. Memory support centres on two DDR5 DIMM slots running in a dual-channel configuration and accepting up to 96 GB total (48 GB per slot). Speeds range from native 4400 MT/s through to 7200 MT/s in overclocked mode. Both AMD EXPO and Intel XMP profiles are recognised automatically by the BIOS, letting enthusiasts push DDR5 frequencies with a straightforward menu toggle. Gigabyte's exclusive DDR5 voltage-unlock circuit can shift native DDR5 PMIC secure mode into programmable mode, broadening overclocking headroom beyond standard limits. Power delivery relies on a 5+2+2 phase digital VRM solution using low RDS MOSFETs, providing stable voltage to the processor under sustained workloads. Storage is handled by one CPU-connected PCIe 4.0 x4 M.2 slot (type 2280) alongside four SATA 6 Gb/s ports, all with RAID 0, 1, and 10 support for both NVMe and SATA arrays. The rear I/O panel includes a DisplayPort 1.4 (up to 3840×2160 at 144 Hz), HDMI 2.1 (up to 4096×2160 at 60 Hz), and a D-Sub output (up to 1920×1200 at 60 Hz), enabling up to three simultaneous displays when using a Ryzen processor with integrated graphics. Networking is provided by a Realtek Gigabit Ethernet controller with bundled bandwidth management software. Audio is handled by a Realtek HD Audio CODEC supporting 2/4/5.1/7.1-channel output. Smart Fan 6 manages up to three fan headers (one CPU, two system), each supporting PWM and DC modes plus an AIO pump, with per-header fan curves adjustable across up to seven control points. FAN STOP allows headers to go completely silent below a user-defined temperature threshold. Q-Flash Plus enables BIOS updates from a USB drive without installing the CPU, memory, or GPU — a practical feature during initial platform setup or after a failed flash. The BIOS is a licensed AMI UEFI implementation stored in a 256 Mbit flash chip, compliant with ACPI 5.0, SM BIOS 2.7, and DMI 2.7.
