Gigabyte B840 Motherboards

The Gigabyte B840 boards here are all micro-ATX AM5 motherboards for DDR5 memory: the B840M D2H, B840M EAGLE WIFI6, B840M DS3H and B840M AORUS ELITE WIFI6E. Each has two M.2 slots and four SATA ports. The D2H and EAGLE WIFI6 have two RAM slots for up to 128 GB, while the DS3H and AORUS ELITE WIFI6E have four slots for up to 256 GB.

B840 is AMD's entry chipset for socket AM5, so these boards take AM5 Ryzen processors. It does not support CPU overclocking, which makes it a sensible match for non-X Ryzen chips in office, study and mid-range gaming builds. Two things decide the choice here. First, Wi-Fi: the EAGLE WIFI6 and AORUS ELITE WIFI6E have it built in, while the D2H and DS3H need a cable or an add-in card. Second, RAM slots: two-slot boards are fine for a 2 x 16 GB or 2 x 32 GB kit, while four-slot boards leave room to add memory later. If you plan to overclock an unlocked Ryzen, a board with a higher-end AMD chipset suits better.
