Overview
The Gigabyte B450M Gaming DDR4 is a Micro ATX motherboard built on AMD's B450 chipset, designed to pair with AMD Ryzen 1st and 2nd Generation processors, Ryzen with Radeon Vega Graphics APUs, and Athlon with Radeon Vega Graphics processors via the AM4 socket. Its compact 24.4 cm × 20.5 cm footprint makes it a practical choice for small-to-mid-size gaming and productivity builds without sacrificing feature depth. Memory support extends to two DDR4 DIMM slots with a maximum capacity of 32 GB in dual-channel configuration. The board accepts speeds ranging from 2133 MHz up to 3200 MHz in overclocked mode, and is compatible with XMP-rated modules for users who want to push memory performance further. Storage is handled by a single M.2 Socket 3 connector supporting 2242, 2260, and 2280 form-factor drives in either PCIe x4 NVMe or SATA mode, alongside four SATA 6 Gb/s ports. RAID 0, RAID 1, and RAID 10 configurations are supported across the SATA ports. Display output options include a D-Sub port (up to 1920×1200 at 60 Hz), a DVI-D port (up to 1920×1200 at 60 Hz), and an HDMI 2.0 port capable of 4096×2160 at 60 Hz with HDCP 2.2 support—useful when pairing with an APU. The networking controller is a Realtek GbE LAN chip supporting 10/100/1000 Mbit connectivity. Audio is handled by a Realtek ALC887 codec delivering High Definition Audio with 2/4/5.1/7.1-channel output and S/PDIF Out support. Expansion slots comprise one PCIe 3.0 x16 slot for a discrete GPU and two PCIe 2.0 x1 slots for additional cards. USB connectivity includes four USB 3.1 Gen 1 ports on the rear panel (via CPU), two rear USB 2.0 ports, two additional USB 3.1 Gen 1 ports via internal header, and further USB 2.0 headers internally. Thermal management is handled by Gigabyte's Smart Fan 5 system, which provides five temperature sensor inputs and three hybrid fan headers that support both PWM and voltage-mode fans. Lighting is managed through RGB Fusion with one addressable RGB LED strip header supporting seven-colour configurations. The BIOS uses a licensed AMI UEFI implementation stored on a 128 Mbit flash chip and supports Q-Flash for firmware updates. The board carries a 3-year manufacturer warranty.
