Socket & processor support

This ATX motherboard uses the Intel LGA 1851 socket and is built for Intel Core Ultra Processors Series 2. The Z890 chipset enables CPU overclocking and provides the platform features enthusiasts expect. Four DDR5 DIMM slots accept up to 256 GB of memory in dual-channel mode.

Memory speed ceiling

Native DDR5 5600 MT/s runs on all configurations, while 1DPC 1R modules can reach 9466 MT/s when overclocked. Intel XMP 3.0 profiles simplify high-frequency setup without manual tuning. Populating all four slots reduces the maximum stable frequency, so plan the kit capacity accordingly.

Installation notes

Standard ATX mounting holes and a pre-installed I/O shield make physical installation straightforward. The primary PCIe 5.0 x16 slot and the CPU-attached M.2 2280 Gen5 socket share CPU lanes; adding a second x16 device forces the top slot to x8 mode. Thunderbolt 4 headers require a compatible add-in card for front-panel Type-C ports.

Questions about this item

Will my existing DDR5 memory run at its rated speed on this board?

The board supports native DDR5 5600 with one DIMM per channel and DDR5 4800 with all four slots populated; higher speeds up to 9466 MT/s are possible through Intel XMP 3.0 profiles.

Can I use both Thunderbolt 4 ports for display output at the same time?

Yes, the rear I/O provides two Thunderbolt 4 Type-C connectors plus one HDMI port, all driven by the processor’s integrated graphics.

How many NVMe drives can I install without losing PCIe 5.0 x16 graphics bandwidth?

Two CPU-attached M.2 sockets (one Gen5 x4, one Gen4 x4) are wired directly to the processor, so a graphics card in the top PCIe 5.0 x16 slot retains full x16 bandwidth.
