Common buying questions
Which CPUs does it support?
Selected AMD Ryzen 3000 and 5000 Series processors, including compatible 3000, 4000 and 5000 G-Series models. Your exact CPU may require a particular BIOS version.
Can I install two M.2 SSDs?
Yes. The CPU-connected slot can support PCIe 4.0 with a compatible processor. The second slot supports PCIe 3.0 x2 SSDs, so the two slots do not have identical capabilities. The board also has four SATA 6 Gb/s ports.
Does it have Wi-Fi and Bluetooth?
Yes. It includes Wi-Fi 6E, Bluetooth 5.3 and Gigabit Ethernet. Using the Wi-Fi 6 GHz band requires compatible network equipment and local availability.
Will the HDMI or DisplayPort work without a graphics card?
Only if your installed processor has compatible integrated graphics. With a CPU that has no integrated graphics, you will need a dedicated graphics card for display output.
Does it support DDR5 or AM5?
No. This motherboard uses DDR4 Memory and the AMD AM4 socket. It does not support DDR5 RAM or AM5 processors.
Before ordering, confirm that your CPU is on GIGABYTE’s support list, your case supports Micro ATX, and the motherboard revision matches the specifications you need. These details are based on GIGABYTE’s published B550M K WIFI6E specifications
