32GB Dual-Channel DDR5 Kit

This Corsair Vengeance RGB kit provides 32GB of DDR5 memory across two 16GB modules. It targets builders using Intel 600 or 700 series and AMD X570 or X670 platforms who need high-speed RAM for gaming or content creation. The grey heat spreader and addressable RGB lighting suit showcase builds.

Intel XMP 3.0 and AMD EXPO Profiles

The kit includes both Intel XMP 3.0 and AMD EXPO profiles for one-click configuration at the rated DDR5 6400 speed. Onboard voltage regulation allows finer tuning through Corsair iCUE software instead of relying solely on motherboard control. This replaces manual BIOS entry for stable operation at 1.40V.

CL32 Timing at 6400 MT/s

Rated timings of 32-40-40-40-84 at CL32 deliver low latency for high-core-count CPUs during rendering, compiling and multitasking. The 32GB capacity handles large project files and heavy browser workloads without paging. Demands beyond 32GB or speeds above 6400 will require a larger or faster kit.

Questions about this item

Will the 288-pin DDR5 modules with the integrated heat spreader fit under a large CPU air cooler?

The modules use a standard 288-pin DDR5 form factor with an aluminium heat spreader; verify your cooler's published RAM clearance height against the module dimensions before purchasing.

How do I enable the rated 6400 speed and CL32 timings on a Z690 or X670 motherboard?

Enter the BIOS, enable the Intel XMP 3.0 or AMD EXPO profile for this kit, save and reboot; the common mistake is leaving the board at default JEDEC speeds instead of activating the profile.

Can the RGB lighting be controlled without installing Corsair iCUE software?

Yes, the onboard LEDs respond to standard motherboard RGB headers and utilities such as ASUS Aura Sync, MSI Mystic Light or Gigabyte RGB Fusion, so iCUE is optional.
