System Setup

We are using an MSI MEG Z890 ACE motherboard with the latest BIOS installed: 7E22v1AA0 dated 3/25/2026. We are testing with an Intel Core Ultra 7 270K Plus CPU. We are using the latest possible Intel Chipset Driver software: 10.1.20398.8776, and we have the Intel Platform Performance Package: 26.03.101.171 installed on both CPUs. We are using a GeForce RTX 5090 FE for all testing with driver 595.97, and we have Windows 11 25H2, all updates to 26200.8117. We are using the Intel Application Optimization Tool with everything enabled. All data was captured at the same time, with the same game patches, and everything was up to date at the time of testing.

SUMMARY

The G.SKILL Trident Z5 CK RGB DDR5 8400MT/s 48GB CU-DIMM Memory is a flagship product from G.SKILL, and provides a CUDIMM option for high-end Intel Core Ultra and Intel Core Ultra Plus CPUs and the Z890 Platform. It truly represents a flagship product, with high-speed options beyond 8000MT/s with multiple XMP profiles, and good timings. It performed very well, and provided an uplift over the default performance, and is built with enthusiasts and overclocking in mind. This memory not only performs great, but also looks great with the mirrored piano black finish and RGB, giving it a unique look.
