Vengeance RGB 64GB DDR5 kit

This Corsair Vengeance RGB kit delivers 64GB of DDR5 memory in a matched pair of 32GB modules. Rated at 6600 MT/s with CL32-39-39-76 timings, it targets enthusiasts who want high bandwidth and low latency for demanding workloads. The black aluminium heat spreader covers ten-zone RGB lighting on each stick.

Dual-channel 288-pin desktop modules

The two modules install in standard DDR5 DIMM slots and run at 1.40V under an Intel XMP 3.0 profile. A dual-channel kit frees the remaining slots on a four-slot board for future expansion while keeping the memory controller load balanced. No extra cables or power connectors are required beyond the slot itself.

iCUE lighting and XMP profile control

Corsair iCUE software drives the ten individually addressable LEDs per module, letting you choose preset effects or build custom colour waves across the panoramic light bar. The same application stores custom XMP 3.0 profiles so you can tune frequency and timings per application without rebooting into the BIOS.

Questions about this item

Will this 64 GB kit fit my Intel 700 series motherboard?

The kit is built for Intel 700 series and some Intel 600 series boards running DDR5. It uses the standard 288-pin DDR5 form factor and runs at 6600 MT/s with Intel XMP 3.0 profiles.

What does the CL32 32-39-39-76 timing mean for real-world speed?

CL32 is the CAS latency at 6600 MT/s. The full 32-39-39-76 sequence sets row-to-column, row-precharge and row-active delays, giving tight response times at the rated 1.40 V.

Do I need extra software to control the RGB lighting?

The ten-zone RGB on each module is managed through Corsair iCUE, where you can pick presets or build custom effects and save them alongside your XMP 3.0 profiles.
