ROG STRIX Z890-H Gaming WiFi S RO Ji Edition

This motherboard is a limited RO Ji edition built for Intel Core Ultra Series 2 processors on the LGA 1851 socket. It targets enthusiasts who want advanced AI computing capabilities and robust power delivery. The board uses the Intel Z890 chipset and provides four DDR5 DIMM slots for high-capacity memory configurations.

Practical limits of the DDR5 memory interface

The board supports up to 256GB of non-ECC unbuffered DDR5 across four slots with a dual-channel architecture. Overclocked speeds can reach 9066+ MT/s, though actual supported data rates depend on the specific CPU and memory modules installed. XMP, AEMP III, DIMM Flex and DIMM Fit features help simplify setup and improve stability within these constraints.

What to check before ordering

Verify that your chosen Intel Core Ultra Series 2 processor is on the ASUS CPU support list for this model. Confirm that your DDR5 modules are compatible with the board's memory QVL for the desired speed and capacity. Ensure your chassis can accommodate an ATX form factor motherboard and that your power supply provides the required ProCool II connectors for the 16+1+2+2 80A power stage design.

Questions about this item

Should I choose this board for a build that needs up to 256 GB of DDR5?

The board provides four DIMM slots with a maximum capacity of 256 GB, so you can populate all four slots with high-capacity modules to reach that limit.

What does the 9066+ MT/s memory speed mean once the system is assembled?

That figure is the overclocked ceiling; actual speeds depend on the installed CPU and memory kit, and you enable the rated profile through XMP or AEMP III in the BIOS.

Which PCIe generation does the Z890 chipset provide and what bandwidth does it cap at?

The chipset delivers PCIe 5.0 lanes, giving each x4 device a theoretical ceiling of roughly 16 GB/s before overhead.
