Gigabyte B650M S2H AMD AM5 Micro-ATX DDR5 Motherboard
The Gigabyte B650M S2H is a micro-ATX motherboard for builders pairing AMD Ryzen 7000, 8000 or 9000 series processors with DDR5 memory. It offers essential AM5 platform features including PCIe 4.0 storage support, dual-channel DDR5 with overclocking profiles, and compact form factor suitable for smaller builds that don't compromise on core connectivity.
Why this product
5+2+2 digital power phases
The VRM design with low RDS(on) MOSFETs delivers stable power to the CPU and memory, enabling reliable overclocking and system scalability.
PCIe 4.0 M.2 storage
One CPU-connected M.2 slot supports fast NVMe drives alongside four SATA ports and RAID support for both NVMe and SATA devices.
DDR5 overclocking to 7200 MT/s
Supports AMD EXPO and Intel XMP profiles with native DDR5 voltage control, allowing memory tuning beyond standard specs on compatible modules.
Micro-ATX for compact builds
Single PCIe x16 slot and two DIMM sockets fit smaller cases while retaining the core features needed for gaming or productivity workloads.
Q-Flash Plus BIOS updates
Update firmware without installing a CPU, memory or graphics card, useful for CPU compatibility refreshes or new generation support.

Best for
- Compact PC builders
- DDR5 memory enthusiasts
- Ryzen 7000/8000/9000 platform builders
- NVMe and SATA storage users
- Builders who overclock
Trade-offs
- Single graphics card only — one PCIe x16 slot limits multi-GPU setups.
- Two memory modules maximum — limited to 128 GB total with two DIMM sockets; full-size ATX boards offer four.
- Budget builds seeking DDR4 — this is a DDR5-only platform; older Ryzen 5000 or earlier series need different boards.

GIGABYTE UD series motherboards use a 5+2+2 phases digital PWM + Low RDS(on) MOSFETs design to support AMD's new generation CPUs by offering incredible precision in delivering power to the motherboard's most power-hungry and energy-sensitive components as well as delivering enhanced system performance and ultimate hardware scalability.
GIGABYTE is offering a tested and proven platform that the memory overclocking capability is able up to 7200 and beyond. All users need to do for achieving this extreme memory performance boost is to ensure that their DDR5 memory modules are AMD EXPO™/ Intel® XMP capable, the EXPO/XMP function is activated and enabled on their GIGABYTE motherboard.
GIGABYTE AM5 MB supports both AMD EXPO™ and Intel® XMP overclocking memory modules for maximal compatibility. MB will automatically detect both profiles format in SPD, users can choose to enable one of profiles from BIOS menu and easily reach overclocked memory performance.
Automatically Boost the Native DDR5 frequency to 5000MHz while the system is under heavy loading by a single click.
Define and create your own SPD profile into Native, AMD EXPO™ and Intel® XMP 3.0 memory modules.
Programmable Mode GIGABYTE's exclusive design unlocks Native DDR5 PMIC secure mode into programmable mode and control Native DDR5 voltage with wide range.
All memory routing is under the PCB inner layer shielded by a large ground layer to protect from external interference.
GbE LAN features a network bandwidth management application which helps to improve network latency and maintain low ping times to deliver better responsiveness in crowded LAN environments.
GIGABYTE B650 Motherboards are ready to work with the PCIe 4.0 devices which are expected to experience twice bandwidth than the current PCIe 3.0 devices. To reach the high speed and maintain good signal integrity, GIGABYTE R&D uses the low impedance PCB to provide the maximum performance.
GIGABYTE motherboards use high-end audio capacitors. These high quality capacitors help deliver high resolution and high fidelity audio to provide the most realistic sound effects for gamers.
GIGABYTE motherboards feature an audio noise guard that essentially separates the board's sensitive analog audio components from potential noise pollution at the PCB level.
Unlock the latch of the PCIe slot easily when remove the graphics card in the PCIe slot.
- GIGABYTE exclusive circuit design unlocks Native DDR5 voltage control
- Transforms Native DDR5 memory module to Overclocked DDR5 memory
- Increases DDR5 memory overclocking performance and capability
- Supports all PMIC vendors for maximum compatibility
