Mini ITX Z390 Board for 8th and 9th Gen Intel

This ASUS ROG Strix motherboard uses the Intel Z390 chipset on a Mini ITX PCB with an LGA 1151 socket. It supports 8th and 9th generation Intel Core i9, i7, i5, i3, Pentium and Celeron processors. The board carries two DDR4 slots and a pre-mounted I/O shield for easier assembly.

Dual M.2 and USB 3.1 Gen 2 Limits

Two M.2 sockets accept 2242, 2260 and 2280 modules running in PCIe 3.0 x4 or SATA modes. When the first M.2 socket operates in SATA mode, the second SATA port is disabled. Four SATA 6Gbps ports and USB 3.1 Gen 2 Type-A plus Type-C connectors provide additional storage and peripheral bandwidth.

Check CPU Generation and Memory Kit

Verify that the processor is an 8th or 9th generation Intel Core part; earlier LGA 1151 CPUs are not supported. The board holds two DIMM slots with a listed maximum of 32 GB, though the manufacturer notes that double-capacity modules can raise the ceiling to 64 GB. Confirm your cooler clears the VRM and M.2 heatsinks in a compact chassis.

Questions about this item

Will this board fit in a standard mini-ITX case and does it need any special mounting hardware?

The board uses the mini-ITX form factor with a pre-mounted I/O shield, so it installs directly into any standard mini-ITX chassis using the regular standoffs and screws supplied with the case.

Which memory kits are supported up to the maximum 64 GB capacity?

Two DDR4 UDIMM slots accept double-capacity modules up to 32 GB each for a total of 64 GB; speeds from 2133 to 4600 are listed, with all frequencies above 2666 requiring overclocking.

Can I run two M.2 drives at full PCIe 3.0 x4 speed simultaneously?

Both M.2 sockets support PCIe 3.0 x4 and SATA modes, but when the first socket runs in SATA mode the second SATA port is disabled; in PCIe mode both drives operate at full x4 bandwidth.
