Crucial DDR5-6400 CUDIMM

DDR5 · 2x16GB

This kit shares its DDR5-6400 speed rating with the Crucial Pro DDR5-6400 kit but uses CUDIMM instead, a clocked unbuffered DIMM architecture that adds an onboard clock driver to the module, a genuine design difference from the UDIMM modules used across the rest of this catalog rather than a naming variation. That architecture shift comes with a tradeoff: CAS 52 timings and 1.1V, both looser and lower-voltage than the Pro UDIMM kit's CL32 at 1.35V. It suits newer platforms that support CUDIMM rather than general DDR5 upgrades.
