GIGABYTE B450M DS3H DDR4 AMD Motherboard

The Gigabyte B450M DS3H is a Micro-ATX motherboard built on the AMD B450 chipset, designed for AMD AM4-socket processors including 1st Generation Ryzen, 2nd Generation Ryzen, and Ryzen processors with Radeon Vega Graphics. Its compact 24.4 cm x 21.5 cm footprint makes it well suited to space-conscious mid-range builds without sacrificing connectivity or feature breadth. Memory support spans four DDR4 DIMM slots capable of holding up to 64 GB of system RAM in dual-channel configuration. Speeds range from DDR4 2133 MHz up to 3200 MHz in overclocked mode, with additional support for XMP profiles so enthusiasts can push memory performance through the AMI UEFI BIOS without manual timing adjustments. Storage flexibility is a clear highlight. A single M.2 Socket 3 connector (M key, types 2242/2260/2280/22110) accepts both PCIe 3.0 x4 NVMe and SATA-mode drives, complemented by four SATA 6 Gb/s ports and support for RAID 0, RAID 1, and RAID 10 arrays across the SATA ports. Display output is handled through an integrated graphics pathway when a compatible Vega-equipped Ryzen APU is installed, offering one DVI-D port (up to 1920×1200 @ 60 Hz) and one HDMI 2.0 port (up to 4096×2160 @ 60 Hz with HDCP 2.2 support). A dedicated discrete GPU can be seated in the full-length PCIe 3.0 x16 slot, with an additional PCIe 2.0 x4 slot and one PCIe 2.0 x1 slot for expansion cards. AMD 2-Way and Quad-GPU CrossFire multi-graphics configurations are supported. Audio is handled by a Realtek ALC887 High Definition codec supporting up to 7.1-channel output (with an HD front-panel audio module) and S/PDIF digital output. Networking runs through a Realtek Gigabit Ethernet (10/100/1000 Mbit) controller paired with cFosSpeed internet accelerator software. USB connectivity includes four USB 3.1 Gen 1 ports on the rear panel (CPU-sourced), four USB 2.0 ports on the rear panel, and additional internal headers supporting two more USB 3.1 Gen 1 and four more USB 2.0 ports. A PS/2 keyboard/mouse port is also present on the rear I/O. Gigabyte’s Smart Fan 5 system provides five temperature sensors and two hybrid fan headers with FAN STOP capability for near-silent low-load operation. RGB Fusion allows customisation of the onboard RGB LED strip header in seven colour modes. The board also includes a TPM header for the GC-TPM2.0 module, a Clear CMOS jumper, and a serial port header.
