Intel Z370 Micro-ATX Motherboard

The MSI Z370M MORTAR uses the Intel Z370 chipset on a Micro-ATX form factor. It accepts 8th Generation Intel Core, Pentium and Celeron processors in an LGA 1151 socket. The board targets builders who want overclocking features in a compact chassis.

64GB Dual-Channel DDR4 Capacity

Four memory slots support dual-channel DDR4 up to a listed maximum of 64GB. Speeds range from 2133 MHz to 4000 MHz with overclocking. The 64GB ceiling suits most gaming and productivity workloads; heavy content creation or virtualisation may require more headroom.

Two PCIe 3.0 x16 Slots for Graphics

The board provides two PCIe 3.0 x16 slots operating in x16/x4 modes plus two PCIe 3.0 x1 slots. This layout allows a single graphics card at full bandwidth or a dual-card setup with the second card at x4 speed. Choose this board if your build needs that specific slot arrangement.

Questions about this item

Will my existing DDR4-2400 memory run at its rated speed on the Z370M MORTAR?

Yes, the board supports DDR4 at 2400 MHz natively alongside higher overclocked speeds up to 4000 MHz.

How can I confirm the 7.1-channel audio is active after building the system?

Open the Realtek audio control panel in Windows and verify 7.1 speaker configuration is selectable and playback tests produce sound from all channels.

Does the box include the I/O shield and a SATA cable, or must I buy them separately?

The package contains the motherboard, one SATA cable and the chassis I/O back panel; no other accessories are included.
