Description
MSI B550 GAMING Motherboard
Designed for AMD Ryzen gaming systems, the MSI B550 GAMING combines the AMD B550 chipset with an AM4 socket, DDR4 memory support, PCIe 4.0 connectivity, dual M.2 storage, 1Gbps LAN, and a comprehensive selection of USB connections. With support for AMD Ryzen 5000 and 3000 Series processors, Ryzen 5000 G-Series and 4000 G-Series processors, up to 128GB of DDR4 memory, and MSI technologies including Core Boost, Memory Boost, M.2 Shield Frozr, and EZ DIY features, it provides a versatile foundation for gaming and everyday high-performance desktop builds.
AMD Ryzen AM4 Platform
The B550 GAMING is built around the AMD B550 chipset and AM4 socket, supporting AMD Ryzen 5000 and 3000 Series desktop processors alongside Ryzen 5000 G-Series and 4000 G-Series processors. It is not compatible with the AMD Ryzen 5 3400G or Ryzen 3 3200G.
DDR4 Memory Support
Four DDR4 DIMM slots provide support for up to 128GB of memory across a dual-channel architecture. Compatible memory can operate at speeds ranging from 2667MHz to 4866+MHz through A-XMP overclocking, with supported speeds dependent on the installed CPU and memory configuration. The board supports non-ECC UDIMM, ECC UDIMM in non-ECC mode, and unbuffered memory.
PCIe 4.0 Expansion
The primary PCIe x16 slot uses PCIe 4.0 connectivity directly from the processor, providing up to x16 bandwidth for compatible graphics cards and expansion hardware. A secondary PCIe x16-length slot operates at PCIe 3.0 x4 through the chipset, while a PCIe 3.0 x1 slot provides additional expansion capability. The primary slot also benefits from MSI Steel Armor reinforcement for improved support of heavier graphics cards.
Dual M.2 Storage
Two M.2 slots provide fast NVMe storage expansion, with the primary M.2_1 slot supporting PCIe 4.0 x4 or SATA mode and compatible 2242, 2260, 2280, and 22110 devices. The secondary M.2_2 slot supports PCIe 3.0 x4 and 2242, 2260, and 2280 devices. Six SATA 6Gbps port
