Overview
The Gigabyte B550 Eagle WiFi 6 is a full-size ATX motherboard built on AMD's B550 chipset with an AM4 socket, making it compatible with AMD Ryzen 5000, Ryzen 4000G, Ryzen 3000, and Ryzen 3000G series processors. It is designed for builders who want a capable, feature-rich platform without stepping up to a premium chipset price point. At the heart of its power delivery is a digital twin 10+3 phase VRM configuration — ten phases dedicated to VCORE and three optimised for SOC — wrapped in a full-metal VRM Thermal Armor heatsink. This design provides stable power to multi-core Ryzen processors and supports memory overclocking via XMP profiles on DDR4 memory. For memory, the board accommodates four DDR4 DIMM slots in dual-channel configuration, supporting up to 128 GB. It accepts ECC and non-ECC unbuffered modules and is rated for speeds up to DDR4-3200, with XMP profile support enabling performance headroom beyond JEDEC defaults. Storage is handled by two M.2 Socket 3 connectors and four SATA 6 Gb/s ports. The primary M.2 slot runs at PCIe 4.0 x4 on Ryzen 5000/3000 series CPUs, enabling high-speed NVMe drives. The primary PCIe x16 slot (PCIEX16) also operates at PCIe 4.0 x16 with Ryzen 5000 and Ryzen 3000 series processors; Ryzen 5000G/4000G/3000G series use PCIe 3.0 x16 on that slot. Four additional chipset-driven PCIe x16 physical slots run at x1 bandwidth (PCIe 3.0) for expansion cards. Connectivity is a strong point: onboard Intel Wi-Fi 6 (802.11ax) with dual-antenna support and Bluetooth 5.0 handle wireless, while Gigabit Ethernet covers wired networking. The rear I/O includes a USB 3.2 Gen 2 Type-A port, a USB 3.2 Gen 1 Type-C port, two additional USB 3.2 Gen 1 ports, four USB 2.0 ports, HDMI video output, three audio jacks, and a Q-Flash Plus button for BIOS updates without a CPU installed. RGB customisation is covered by two addressable ARGB headers, two standard RGB LED headers, and one combined CPU cooler LED/RGB header internally. Three system fan headers plus dedicated CPU fan and CPU fan/pump headers give comprehensive cooling control. **Verified Specifications** - Socket: AM4 - Chipset: AMD B550 - Compatible CPUs: Ryzen 5000 / 5000G / 4000G / 3000 / 3000G series - Form Factor: ATX - Memory: 4× DDR4 DIMM, dual-channel, up to 128 GB, up to DDR4-3200, XMP support - Primary PCIe slot: PCIe 4.0 x16 (Ryzen 5000/3000) or PCIe 3.0 x16 (G-series) - M.2 slots: 2× M.2 Socket 3 (primary supports PCIe 4.0) - SATA ports: 4× SATA 6 Gb/s - USB rear I/O: 1× USB 3.2 Gen 2 Type-A, 1× USB 3.2 Gen 1 Type-C, 2× USB 3.2 Gen 1, 4× USB 2.0 - Display: 1× HDMI - Networking: Gigabit LAN, Wi-Fi 6, Bluetooth 5.0 - VRM: 10+3 phase digital twin - Warranty: 3 years
