Overview
The GIGABYTE B850 Gaming X WiFi 6E is a full-size ATX motherboard (30.5 cm x 24.4 cm) built on the AMD B850 chipset and the AM5 socket platform. It is compatible with AMD Ryzen 9000, Ryzen 8000, and Ryzen 7000 Series processors, making it a versatile choice for both current and upcoming AMD CPU generations. Memory support is extensive: four DDR5 DIMM slots accommodate up to 256 GB of system RAM (64 GB per slot maximum) in a dual-channel configuration, with speeds ranging from native 4400 MT/s up to 8200 MT/s via overclocking. Both AMD EXPO and Intel XMP memory profiles are supported, enabling straightforward memory optimisation directly from the BIOS. The board also ships with GIGABYTE's AORUS AI SNATCH and X3D Turbo Mode BIOS features, which apply one-click CPU and memory tuning profiles for users seeking easy performance uplift without manual overclocking. Storage expansion is handled by three M.2 connectors — two CPU-attached (M2A_CPU and M2B_CPU, supporting up to PCIe 5.0 x4 and PCIe 4.0 x4 respectively with Ryzen 9000/7000 processors) and one chipset-attached (M2C_SB, PCIe 4.0 x4). Four SATA 6 Gb/s ports round out the storage options, with RAID 0, 1, 5, and 10 support for NVMe devices (RAID 5 limited to Ryzen 9000 Series). The primary PCIe x16 slot runs at PCIe 5.0 x16 with Ryzen 9000/7000 processors, while two additional PCIe x16 physical slots (electrically x1, PCIe 3.0) provide further expansion. Wireless connectivity is provided by a Realtek RTL8852CE module supporting Wi-Fi 6E across 2.4 GHz, 5 GHz, and 6 GHz bands with 160 MHz channel width and 11ax standard, alongside Bluetooth 5.3. Wired networking uses a Realtek 2.5GbE LAN chip supporting 2.5 Gbps, 1 Gbps, and 100 Mbps speeds. The rear I/O panel includes one USB Type-C port (USB 3.2 Gen 2), one USB 3.2 Gen 2 Type-A (red), three USB 3.2 Gen 1 Type-A, three USB 2.0 ports, one HDMI 2.1 output (up to 4096x2160 at 60 Hz), one DisplayPort 1.4 output (up to 3840x2160 at 144 Hz), a PS/2 port, RJ-45, two antenna connectors (2T2R), and three audio jacks. An internal USB Type-C header supports USB 3.2 Gen 2x2 (20 Gbps). Fan headers support both PWM and DC modes at up to 24 W (12 V x 2 A) each, with built-in over-current protection and Fan Stop functionality for silent operation at low loads. The PCB incorporates GIGABYTE's AI-Driven PCB Technology suite — AI-ViaFusion, AI-Trace, and AI-Layer — for signal integrity optimisation across layers. The BIOS is a licensed AMI UEFI implementation with GIGABYTE's User-Centred (UC) interface, supporting Q-Flash Plus (BIOS update without a CPU installed), multi-theme options, and EZ Debug Zone LEDs for streamlined system diagnosis. RGB management is handled via three ARGB Gen2 headers and one standard RGB header, controllable through GIGABYTE Control Center (GCC) software.
