GIGABYTE B550 Aorus Elite V2 DDR4 AMD Motherboard

The Gigabyte B550 Aorus Elite V2 is an ATX-form-factor motherboard built on the AMD B550 chipset with an AM4 socket, making it a solid foundation for AMD Ryzen 5000 Series, Ryzen 5000 G-Series, Ryzen 4000 G-Series, and Ryzen 3000 Series processors. Its 12+2 phase Digital Twin Power Design, each phase rated at 50A DrMOS, delivers stable current to the CPU under sustained workloads, supported by enlarged-surface heatsinks across the VRM and chipset areas to manage thermals effectively. Memory flexibility is a standout characteristic of this board. Four DDR4 DIMM slots support up to 128 GB of system memory — with single-module capacity up to 32 GB — across a wide speed range from 2133 MHz up to 4733 MHz (overclocked). Both ECC and non-ECC unbuffered modules are supported (ECC capability depends on CPU), and XMP profiles are recognised for one-step memory tuning. Storage options are equally comprehensive. A primary M.2 slot (M2A_CPU) connects directly to the CPU and supports PCIe 4.0 x4 NVMe drives on Ryzen 5000 and 3000 Series processors, while a second M.2 slot (M2B_SB) connects through the chipset and supports PCIe 3.0 x4 NVMe as well as SATA drives. The first slot is paired with a thermal guard to keep drive temperatures in check. Four SATA 6 Gb/s ports add further storage bandwidth and support RAID 0, 1, and 10 configurations. Connectivity is handled by a Realtek 2.5GbE LAN controller and a comprehensive USB arrangement: two USB 3.2 Gen 2 Type-A ports and three USB 3.2 Gen 1 ports on the rear panel, plus a front-panel USB 3.2 Gen 1 Type-C header. Display output for systems using an AMD APU is provided through one DisplayPort 1.4 (up to 5120×2880 @ 60 Hz) and one HDMI 2.1 port (up to 4096×2160 @ 60 Hz), both with HDCP 2.3 and HDR support. Audio is managed by a Realtek ALC1200 codec with WIMA capacitors, delivering up to 7.1-channel HD audio and an optical S/PDIF output. RGB Fusion 2.0 allows customisation through two ARGB headers and two standard RGB headers. Smart Fan 5 provides per-header fan and pump control with hybrid fan-stop functionality. BIOS updates can be performed without a CPU or memory installed using the Q-Flash Plus button on the rear panel.
