Intel Z390 Micro-ATX for LGA 1151 300 Series

This MSI MAG Z390M MORTAR motherboard uses the Intel Z390 chipset on a Micro-ATX form factor. It supports 9th and 8th Generation Intel Core, Pentium Gold and Celeron processors in the LGA 1151 300 Series socket. The board provides four DDR4 memory slots with a maximum capacity of 64 GB running in dual-channel mode. Integrated graphics output is available only when the installed CPU includes an integrated graphics engine.

Check CPU generation and cooler clearance

Verify that your processor is a 9th or 8th Generation Intel part for the LGA 1151 300 Series socket; older LGA 1151 CPUs are not supported. Confirm that your chassis can accept a Micro-ATX board and that your CPU cooler fits the socket mounting pattern. The board offers two full-length PCI Express 3.0 x16 slots, one PCI Express x1 slot, four SATA 6Gb/s ports, two M.2 sockets and one M.2 Key E slot reserved for an Intel CNVi wireless module.

Builders needing Z390 features in a compact layout

This board suits system builders who want Z390 overclocking features and dual x16 slots in a smaller Micro-ATX footprint. It is not suitable for users with 6th or 7th Generation Intel processors, for those requiring more than two M.2 devices or more than four SATA drives, or for anyone needing built-in Wi-Fi without adding a CNVi module.

Questions about this item

What comes in the box with the MAG Z390M MORTAR and what must I buy separately?

The board includes the motherboard, I/O shield, SATA cables and driver disc. You must buy a compatible LGA 1151 (300 Series) CPU, DDR4 memory modules, storage drives and a power supply separately.

Which DDR4 speed should I choose for the MAG Z390M MORTAR from the supported list?

The board natively runs DDR4 2666 and supports overclocked speeds up to DDR4 4400 (OC). Pick a kit rated for your target speed and enable the XMP profile in BIOS.

What does the 64 GB maximum memory figure mean once the board is in a real machine?

You can populate all four 288-pin slots with up to 16 GB DDR4 modules each, giving a total of 64 GB running in dual-channel mode.
