64GB Dual-Channel DDR5 Kit

This Corsair Vengeance RGB kit delivers 64GB of DDR5 memory across two 32GB modules. It is built for desktop systems that use 288-pin DIMM slots. The memory operates at 5600 MT/s with a CAS latency of CL40.

Suits Intel 600 and 700 Series Builds

The kit is validated for Intel 600 and 700 series platforms and uses Intel XMP 3.0 profiles for simple configuration. It runs at 1.25V. Builders on other chipsets or those needing lower latency timings should verify compatibility before purchase.

5600 MT/s Speed Decides Fit

The single specification that determines suitability is the 5600 MT/s data rate. Your motherboard and CPU must support this DDR5 speed to gain the rated bandwidth; otherwise the modules will downclock to the highest mutually supported frequency.

Questions about this item

Will the 288-pin DDR5 modules with heat spreaders clear my CPU cooler?

Each module is a standard 288-pin DDR5 DIMM with an integrated black heat spreader; verify your cooler's published RAM clearance height against the module height before purchase.

How do I enable the rated 5600 speed and CL40-40-40-77 timings on my Intel 600 or 700 series board?

Enter the BIOS, locate the Intel XMP 3.0 profile for this kit, select Profile 1, save and reboot; the common mistake is leaving the board on Auto so it trains at a lower JEDEC speed.

What upkeep does the ten-zone RGB lighting and heat spreader need over time?

Dust the light bar and heat spreader fins with compressed air every few months; the LEDs are sealed and non-replaceable, and the modules have no user-serviceable parts.
