Crucial Pro DDR5-6400 Overclocking Memory Spec and Price in Spain

DDR52x16GBUDIMM10.00 ns true latency

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.

Tied 19th of 139 models in the RAM catalog on Speed — 19 models share this figure.

What owners and reviewers say

Summarised from 2 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices

Commonly praised

  • Reviewers found it performs well on Intel platforms and ships with a low-profile heat spreader that keeps clearance easy.
  • It supports both Intel XMP and AMD EXPO profiles, so the rated speed can be enabled on either platform.
  • Owners report it runs at the rated speed via the memory profile and has a clean, low-profile design.

Commonly criticised

  • Its performance on AMD platforms was below par relative to the Intel results.
  • There is little overclocking headroom beyond the rated profile.
  • Owners see few gains over slower, cheaper DDR5 kits in most workloads, and pricing tracks the wider memory market.
