Manufacturer description

The GIGABYTE B550M AORUS Elite AX (rev 1.3) is a micro-ATX AM4 motherboard for Ryzen 5000, 4000 and 3000 Series processors. It suits a compact gaming build or an upgrade on a platform you already own. Power comes through a pure digital 5+3 phase design with premium chokes and capacitors. An enlarged MOSFET heatsink keeps the VRM cooler under sustained load. You get four DDR4 DIMM slots with Extreme Memory Profile support, so you can enable rated memory speeds without tuning timings by hand. For expansion there is an Ultra Durable PCIe 4.0 x16 slot for your graphics card. Storage gets one…

Frequently Asked Questions

Which CPUs work with the GIGABYTE B550M AORUS Elite AX?

It uses AMD Socket AM4 and supports Ryzen 5000, 4000 and 3000 Series processors. Check GIGABYTE's CPU support list for the BIOS version your specific chip needs.

Yes. Q-Flash Plus lets you flash the BIOS from a USB drive with no CPU, RAM or GPU installed. That helps if your board shipped with an older BIOS than your Ryzen chip needs.

How many NVMe SSDs can I install?

Two. One M.2 slot runs at PCIe 4.0 and the other at PCIe 3.0. Put your boot drive in the PCIe 4.0 slot for the best speeds.

Does it have built-in WiFi and Bluetooth?

Yes. It includes WiFi 6E with 6 GHz band support, Bluetooth 5.3 and a GbE LAN port with bandwidth management.

What memory does this motherboard support?

DDR4 only, across 4 DIMM slots, with Extreme Memory Profile (XMP) support. It does not accept DDR5. See GIGABYTE's memory support list for the maximum capacity and validated kits.
