Speed DDR5 6400 (PC5 51200)

Cas Latency CL32 · Black RGB

  • High capacity 64GB dual-channel kit for demanding workloads
  • DDR5 6400 speed delivers high bandwidth for responsive performance
  • CL32 32-40-40-84 timings provide tight response times
  • Intel XMP 3.0 support enables simple BIOS performance tuning
  • Ten-zone RGB lighting with iCUE customisation for personalised aesthetics

Capacity and purpose

This kit delivers 64GB of DDR5 memory across two 32GB modules for desktop systems. It targets users who need high capacity and fast data rates for intensive workloads or gaming. The dual-channel configuration helps maximise throughput on compatible platforms.

Thermals noise and power

A black heat spreader covers each module to dissipate heat during sustained loads. Operating voltage is set at 1.40V to reach the rated DDR5 6400 speed with CL32 timings. No active cooling is included so airflow in the case manages temperatures.

Lighting and software control

Ten individually addressable RGB LEDs per module sit behind a panoramic light bar for wide-angle illumination. Corsair iCUE software provides preset lighting profiles and lets users create custom effects. The same utility allows custom Intel XMP 3.0 profiles to be saved and applied per application or task.

Questions about this item

How do I install the 288-pin DDR5 modules and enable the Intel XMP 3.0 profile, and what step is often missed?

Align the notch on each module with the motherboard slot key, press down firmly until both retention clips click, then enter the BIOS to enable the Intel XMP 3.0 profile so the kit runs at DDR5 6400 CL32 instead of the default JEDEC speed.

What maintenance will the ten-zone RGB light bar and heat spreader need over time?

Use compressed air to clear dust from the heat spreader fins and light bar every few months; the LEDs are sealed and require no further service, while the aluminium spreader passively cools the memory ICs without moving parts.

What limit appears first during sustained loads — the CL32 latency ceiling or the 1.40 V thermal ceiling?

The 1.40 V operating voltage is the first constraint; prolonged heavy workloads raise module temperature until the heat spreader reaches its dissipation limit, at which point the system may throttle before the CL32 timing becomes unstable.
