MSI MAG B550 TOMAHAWK MAX WIFI Socket AM4 DDR4 128GB AMD motherboard

AM4 Ryzen motherboard with 128 GB DDR4 limit

The MSI MAG B550 TOMAHAWK MAX WIFI fits Socket AM4 and supports third-generation Ryzen CPUs along with future Ryzen releases after a BIOS update. Dual-channel DDR4 runs at speeds from 1866 up to 4866 MHz and tops out at 128 GB total capacity. Two M.2 interfaces and six SATA ports provide ample storage connectivity for builders and upgraders.

Extended heatsinks and dual LAN with 2.5 Gbps

An extended heatsink design covers the VRM and chipset to keep temperatures steady under typical loads without adding fan noise. The board carries two Realtek controllers: an RTL8125B running at 2.5 Gbps and an RTL8111H at 1 Gbps, giving wired network flexibility for gaming or workstations. Power delivery remains stable through standard ATX connectors with no extra cables required.

Dual-channel DDR4 up to 4866 MHz and 128 GB

Memory support is the decisive spec: the board validates dual-channel DDR4 from 1866 MHz through 4866 MHz and caps at 128 GB across four slots. If your build needs that speed range and maximum capacity on AM4, this chipset delivers it; if you need more memory or a different socket, look elsewhere.
