Crucial Pro DDR5-6400 Overclocking Memory

DDR5 · 2x16GB

This DDR5-6400 configuration holds CL32 timings (32-40-40-103) at 1.35V, tighter latency than the Pro DDR5-6000 kit's CL36 despite the higher clock speed — a meaningful step up within Crucial's overclocking-focused range. Both Pro kits share the same 32GB, UDIMM, non-RGB layout, so the difference comes down to frequency and timing headroom. It targets DDR5 builders who want to push clocks higher without loosening latency.
