LGA 1151 Micro ATX board

The ASRock Z390M Pro4 is an Intel Z390 motherboard in a Micro ATX form factor. It accepts LGA 1151 processors from the Core i7, i5, i3, Pentium and Celeron ranges. The board provides one PCI Express 3.0 x16 slot, one PCI slot and two M.2 sockets. It is supplied as the motherboard only, without an I/O shield or other accessories.

Builders needing compact Z390 features

This board suits builders who want Z390 overclocking features in a smaller Micro ATX chassis. It fits systems that can use a single graphics card and up to two M.2 drives. Buyers who need multiple PCI Express 3.0 x16 slots for multi-GPU configurations should look elsewhere. Users who require an included I/O shield or bundled cables must source those separately.

128 GB DDR4 maximum memory

The board supports up to 128 GB of DDR4 memory across its four slots. This capacity ceiling is the key figure when planning a high-memory workstation or server build. If the intended workload demands more than 128 GB, this motherboard cannot meet the requirement.

Questions about this item

How do I install this LGA 1151 board into a Micro ATX case without missing a standoff?

Align the Micro ATX screw holes with the case standoffs, secure all six mounting points, then attach the CPU cooler bracket before inserting the processor into the LGA 1151 socket.

Which components on the Z390M Pro4 will need replacement first under normal use?

The CMOS battery on the board typically lasts several years; replace it when the system loses time or BIOS settings after power loss.

What thermal limit appears first when the VRM runs a sustained load on this Z390 chipset board?

The VRM heatsinks have no active cooling, so temperatures can reach 45 °C or higher during prolonged heavy CPU workloads.
