Our take on the Corsair Vengeance DDR5 6400MHz 2x16GB (CMK32GX5M2B6400Z32)

The Corsair Vengeance DDR5 6400 kit is a 2x16GB dual-channel desktop memory set rated at 6400 MT/s with CL32 timings at 1.4V. It carries both Intel XMP 3.0 and AMD EXPO profiles, so a single BIOS toggle gets it to its rated speed on either platform. It is a plain black, no-RGB module aimed at builders who want fast DDR5 without paying for lighting. Against pricier 6400 and 7000 kits it gives up nothing in rated speed but has looser CL32 timings than low-latency rivals, and its tall heat spreaders can crowd large air coolers.

  • Rated speed depends on the motherboard and CPU memory controller

Questions and answers

Does it work on both Intel and AMD?
Yes. It has both Intel XMP 3.0 and AMD EXPO profiles, so it can run at its rated speed on either platform.
Will it run at 6400 MT/s out of the box?
Not until you enable XMP or EXPO in the BIOS. Even then, the CPU memory controller and motherboard decide whether 6400 is stable.
Is 32GB enough for gaming?
Yes for most games and everyday multitasking. Heavy video editing or many virtual machines may want more.
Does it have RGB lighting?
No. It is a plain black module with no lighting.
Will it fit under a large air cooler?
Check your cooler's clearance. The heat spreaders are tall and can conflict with big tower coolers.
Is it a single 32GB stick?
No, it is two 16GB modules meant to run as a dual-channel pair.
