64GB Dual-Channel DDR5 Kit

This Corsair Vengeance RGB kit delivers 64GB across two 32GB modules for desktop systems. It targets users who need high capacity for demanding workloads or gaming. The modules operate at DDR5 6400 with a CL32 latency profile. Intel XMP 3.0 support allows simple one-click configuration on compatible platforms.

DDR5 6400 Interface Limits

The DDR5 6400 standard provides a peak transfer rate of PC5 51200. Real-world throughput is lower due to protocol overhead and system latency. The kit runs at 1.40V with timings of 32-40-40-40-84. Stability at this frequency depends on motherboard trace quality and memory-controller strength.

64GB Capacity and Headroom

Two 32GB modules fill a dual-channel configuration, giving 64GB total addressable space. This handles large content-creation projects, heavy multitasking and modern titles with headroom to spare. Workloads that exceed 64GB will page to storage, introducing latency. The ten-zone RGB lighting adds visual customisation without affecting thermal performance.

Questions about this item

Should I choose the 64GB dual-channel kit or a different capacity for my DDR5 build?

The CMH64GX5M2N6400C32 is sold only as a 64GB kit containing two 32GB modules. If you need 64GB total this is the correct kit; other capacities would require a different part number.

What does the 6400 MT/s speed mean once the memory is installed in my system?

DDR5 6400 (PC5 51200) delivers a peak transfer rate of 51200 MB/s when the XMP 3.0 profile runs at the rated 1.40V and CL32 timings.

Does the Intel XMP 3.0 profile work on any DDR5 motherboard or are there limits?

XMP 3.0 is an Intel specification; the kit is validated for Intel 600, 700 and 800 series chipsets including B660, B670, B760, Z690 and Z790. Other platforms may run at JEDEC speeds instead.
