Capacity and channel layout

This kit delivers 48 GB across two 24 GB modules in a dual-channel configuration. It is built for enthusiasts and overclockers who want maximum throughput on Intel Core Ultra 200 K-series platforms. The 288-pin CU-DIMM form factor fits standard desktop DIMM slots.

Build integration and signal stability

A built-in clock driver chip on each module strengthens the clock signal from the memory controller to the DRAM. This improves stability at high frequency and reduces the burden on motherboard trace routing. The kit relies on Intel XMP 3.0 profiles for one-click configuration on Z890 chipset motherboards.

Speed headroom and voltage limits

Rated at DDR5 8400 with timings of 40-52-52-134 at 1.40 V, the modules provide substantial frequency headroom for memory-intensive workloads. The 1.40 V operating voltage is the upper bound for daily use; pushing beyond the validated profile requires advanced cooling and motherboard support not covered by the XMP profile.

Questions about this item

Will this kit fit a motherboard with standard 288-pin DDR5 slots?

Yes, the modules use the standard 288-pin DDR5 form factor and will install in any desktop board with DDR5 DIMM slots.

What motherboard and CPU combination is this memory validated for?

The kit is developed for Intel 800 series chipsets, specifically Z890, and Intel Core Ultra 200 K-series desktop processors.

Does the 1.40 V operating voltage require manual BIOS adjustment or is it handled automatically?

The kit includes an Intel XMP 3.0 profile that sets the 8400 MT/s speed, CL40 timings and 1.40 V voltage automatically when enabled in the BIOS.
