Frequently Asked Questions

How do I reach 6400 MT/s at CL38?
Enable the Intel XMP 3.0 or AMD EXPO profile in your motherboard BIOS. Without it the kit runs at a safe JEDEC default speed.
Will DDR5-6400 run on AMD Ryzen?
Many AM5 boards run 6400 via EXPO, though some Ryzen setups are most stable at 6000. Check your board and CPU support; otherwise it runs at the highest stable speed.
What differs on the black version?
Only the heatspreader colour. CP2K16G64C38U5B is black and CP2K16G64C38U5W is white; the specifications are identical.
Is 32GB enough for gaming?
Yes, 32GB is the current mainstream sweet spot for gaming, with headroom for streaming and background apps.
Singular Expert Insight
This Pro Overclocking kit balances speed and latency well: 6400 MT/s at CL38 is quicker than typical CL40 kits at the same speed. On Intel it is effortless via XMP 3.0; on AMD AM5, EXPO works but a DDR5-6000 kit can be the more stable 1:1 choice for some Ryzen builds. Pick black here or the CP2K16G64C38U5W white variant to match your build.

Buyer's Guide

Buy it if

You want fast, low-latency 6400 CL38 32GB memory for an Intel or high-end AMD gaming rig in black.

Skip it if

You need 64GB capacity, or a Ryzen build where DDR5-6000 is the more stable pick.

Also consider

White CP2K16G64C38U5W for the same spec, or a DDR5-6000 kit for AMD 1:1 stability.
