Socket LGA 1851 ATX motherboard

The ASRock Z890 Taichi is an ATX motherboard built for Intel Core Ultra Processors (Series 2) on the LGA 1851 socket. It uses the Intel Z890 chipset and targets enthusiasts who want high memory capacity and fast storage options. The board supports up to 256GB of DDR5 across four 288-pin slots running in dual-channel mode.

256GB DDR5 maximum capacity

The single specification that decides fit is the 256GB maximum memory limit across four DDR5 slots. Native speeds reach 5600MHz with one DIMM per channel and 4800MHz when all four slots are populated. Overclocked profiles via Intel XMP 3.0 can push supported modules to 9600MHz+(OC) depending on configuration. Buyers needing more than 256GB must choose a different platform.

Standard ATX installation with slot-sharing notes

Installation follows normal ATX mounting in a compatible case with standard power and front-panel connectors. The top PCIe 5.0 x16 slot runs from the CPU and shares bandwidth if a riser card splits it to x8/x8 or x8/x4/x4. The second PCIe 4.0 x16 slot runs at x4 from the chipset; populating it disables the M2_4 M.2 socket. Builders should plan GPU and NVMe placement around these links.

Questions about this item

What does the 256 GB maximum memory mean for a build?

You can populate all four DDR5 slots up to 256 GB total, running in dual-channel mode with Intel XMP 3.0 profiles.

How does the PCIe 5.0 x16 slot limit graphics or add-in cards?

The primary slot runs at PCIe 5.0 x16 from the CPU and can be split to x8/x8 or x8/x4/x4 with a riser card.

What clearance and mounting does the ATX board need?

Standard ATX dimensions with LGA 1851 socket, four 288-pin DDR5 slots, and M.2 sockets for 2260 or 2280 drives.
