MODEL / REVISION WARNING: Similar names, Wi-Fi variants and PCB revisions can differ in wireless hardware, connectors, lane routing and firmware. Identify the exact model and revision before installation or BIOS updates.

Specifications

Model / chipsetMSI MAG X870 TOMAHAWK WIFI — AMD X870, 2024
Socket / processor compatibilitySocket AM5 and X870 chipset. Only CPUs present in MSI's MAG X870 TOMAHAWK WIFI compatibility table are supported, and BIOS version may be required for newer Ryzen generations.
MemoryFour DDR5 DIMM sockets, dual-channel and EXPO support. Maximum capacity and validated speeds are subject to CPU memory controller, BIOS and MSI's DIMM QVL.
Form factorATX (305 × 244 mm)
PCI Express expansionPrimary CPU slot supports PCIe 5.0 x16; secondary x16-length expansion runs at reduced electrical width. PCIe lane distribution and M.2 sharing depend on the installed CPU and device population.
StorageFour M.2 sockets, including CPU-connected PCIe 5.0 x4 storage and PCIe 4.0 sockets, plus four SATA 6 Gb/s ports. Consult MSI's manual for socket lengths and shared lanes.
Rear I/OTwo rear USB4 40Gb/s Type-C ports, USB 3.2 Type-A/C and USB 2.0 ports, HDMI, 5GbE, Wi-Fi antenna connectors, audio and Flash BIOS button.
Networking / audio5Gb Ethernet, Wi-Fi 7 / Bluetooth and onboard multichannel audio; exact wireless operation requires the included antenna.
Firmware / compatibilityUEFI support, CPU list and minimum BIOS are model-specific. AM5 uses DDR5 only. Match the case to the stated board dimensions, use the correct EPS/ATX power leads, install the AM5 cooler with its supported mounting hardware, and check the manual's lane-sharing/connector tables before populating M.2 and PCIe devices.

Compatibility notes

AM5 processors are not interchangeable with AM4 CPUs. Consult the manufacturer's CPU support list for the exact board and verify the required BIOS before purchasing or installing a processor. A BIOS flash utility does not make an unlisted CPU compatible.

DDR5 EXPO profiles are memory overclocking; stability, capacity and transfer rate depend on the CPU memory controller, DIMM type/population, firmware and the board's validated memory list. Storage protocols, expansion-slot widths, graphics lane reduction, SATA disablement and USB functionality depend on the connector and lane-sharing rules described in the current manual.

Confirm the physical dimensions and standoff layout against the chassis, install only the correct AM5 cooler hardware, connect required CPU power leads, and use the supplied Wi-Fi antenna where fitted. Firmware updates must match this exact model/revision and follow the manufacturer's procedure.

Preservation and handling

AM5 is an LGA socket: protect its exposed contacts from handling damage and contamination. Before installation, inspect the socket, DIMM slots, M.2 thermal pads, rear-I/O shield and power connectors. Record PCB revision, serial/date codes and BIOS version; retain the original packaging and document test conditions and any repairs.
