GIGABYTE B550 Gaming X V2 DDR4 AMD Motherboard

The Gigabyte B550 Gaming X V2 is an ATX-form-factor motherboard (305 mm × 244 mm) built on the AMD B550 chipset for the AM4 socket. It supports AMD Ryzen 5000 Series processors as well as 3rd Generation Ryzen and 3rd Generation Ryzen with Radeon Graphics processors, making it a solid foundation for mid-range AMD gaming builds. Power delivery is handled by a 10+3 phase pure digital VRM solution with low RDS MOSFETs, fed through a standard 8-pin ATX 12V connector alongside the 24-pin main power connector. This design helps maintain stable voltage under sustained CPU loads. Memory support spans four DDR4 DIMM slots with a maximum capacity of 128 GB (32 GB per DIMM). The board runs dual-channel memory architecture and accepts both ECC and non-ECC unbuffered modules. XMP profiles are supported, with overclocked speeds reaching up to DDR4-4400 (O.C.) for Ryzen processors and DDR4-4733 (O.C.) for Ryzen with Radeon Graphics processors. Storage is covered by two M.2 connectors: the CPU-connected M2A_CPU slot supports PCIe 4.0 x4 NVMe SSDs (with Ryzen 5000 / 3rd Gen Ryzen), while the chipset-connected M2B_SB slot supports PCIe 3.0 x4 NVMe and SATA SSDs. Both accept 2242, 2260, 2280, and 22110 form factors. Four SATA 6 Gb/s ports with support for RAID 0, 1, and 10 round out the storage connectivity. The primary PCIe x16 slot operates at PCIe 4.0 x16 with Ryzen 5000 and 3rd Gen Ryzen CPUs, dropping to PCIe 3.0 x16 with APU variants. Additional expansion includes one PCIe 3.0 x2 slot and three PCIe 3.0 x1 slots. The rear I/O panel features one USB 3.2 Gen 2 Type-A port (red), three USB 3.2 Gen 1 Type-A ports, two USB 2.0 ports, one HDMI 2.1 port (up to 4096×2160 @ 60 Hz, HDCP 2.3, HDR), one DVI-D port (up to 1920×1200 @ 60 Hz), one PS/2 keyboard/mouse port, one RJ-45 Gigabit LAN port, and three audio jacks. The Realtek ALC887 codec delivers High Definition Audio with 2/4/5.1/7.1-channel output. Networking is handled by a Realtek GbE LAN chip (1000/100 Mbit) with an included bandwidth management utility. RGB Fusion 2.0 provides control over the onboard addressable LED strip headers (×2) and standard RGB LED strip headers (×2), plus a dedicated CPU cooler RGB header. Smart Fan 5 manages up to five fan/pump headers (one CPU, one water-cooling CPU, three system) with individual PWM/voltage mode selection and multiple temperature sensor inputs. Q-Flash Plus allows BIOS updates from a USB drive without a CPU or memory installed.
