Gigabyte B450M H Motherboard:
The Gigabyte B450M H (rev. 1.x) Motherboard is a micro-ATX motherboard built on the AMD B450 chipset. It’s designed to support a wide range of AMD Ryzen™ processors, including the 5000 series, 5000 G-Series, 3rd Gen, 2nd Gen, 1st Gen Ryzen™, and Athlon™ processors with Radeon™ Vega Graphics. This motherboard offers a solid and reliable platform for building a compact yet capable system, focusing on essential features and Gigabyte’s “Ultra Durable” design principles.
Key Features for Reliable Performance:
The B450M H features a 4+3 Phase Hybrid Digital PWM design, ensuring stable power delivery to the CPU. It supports Dual Channel Non-ECC Unbuffered DDR4 RAM across two DIMM sockets, with a maximum capacity of 64GB (32GB single DIMM capacity). It supports RAM speeds up to 3600MHz (O.C.) and is compatible with Extreme Memory Profile (XMP) RAM modules.
For storage, the motherboard includes an Ultra-Fast PCIe Gen3 x4 M.2 Connector, which supports both PCIe NVMe and SATA mode SSDs (actual support may vary by CPU). This allows for fast boot times and quick loading of applications and games. Additionally, it provides four SATA 6Gb/s connectors with support for RAID 0, RAID 1, and RAID 10 configurations. The motherboard also supports AMD StoreMI technology, which combines the speed of SSDs with the high capacity of HDDs into a single drive for improved responsiveness.
Connectivity is handled by the Realtek GbE LAN with Bandwidth Management, which helps to improve network latency and ensure a smooth online experience. For integrated graphics output (when using compatible AMD Ryzen™ APUs with Radeon™ Vega Graphics), it offers D-Sub and HDMI ports for multiple display support.
The motherboard incorporates Smart Fan 5, featuring multiple temperature sensors and hybrid fan headers. This allows users to precisely control cooling performance and utilize the Fan Stop function for quieter operation when system temperatures are low.
The B450M H emphasizes “Ultra Durable” features, including High Quality Audio Capacitors and Audio Noise Guard Design for improved sound quality. It also features leading static-electricity and surge protection to safeguard the motherboard and its components. The motherboard supports RGB Fusion, allowing for customization with RGB LED strips in 7 colors.
