Gigabyte B450 Motherboards

The Gigabyte B450 boards here are all micro-ATX AM4 motherboards for AMD Ryzen processors, using DDR4 memory, one M.2 slot and four SATA ports. The B450M DS3H WIFI and B450M DS3H V3 have four RAM slots, with the WIFI version adding built-in wireless. The B450M K is the simpler board, with two RAM slots and half the maximum memory capacity of the DS3H pair.

Choosing between them comes down to memory slots and networking. For a basic office or home PC running a two-stick memory kit, the B450M K is enough. If you want room to add RAM later without replacing the sticks already fitted, and a higher memory ceiling, pick one of the DS3H boards. Take the DS3H WIFI when the PC sits away from the router and running a cable is not practical, and the DS3H V3 when wired Ethernet will do. B450 is a PCIe 3.0 platform, so PCIe 4.0 SSDs and graphics cards work but run at PCIe 3.0 speed.
