Corsair CMH5X16G1B56C40A2 16GB Review
Want a single RGB-lit DDR5 stick instead of a full kit? The Corsair CMH5X16G1B56C40A2 is a standalone 16GB Vengeance RGB module at DDR5-5600 CL40.
This gets you Corsair's ten-zone Vengeance RGB lighting on a single 16GB stick — useful for adding capacity to an existing Vengeance RGB build without needing a matched kit, though the 5600MT/s CL40 spec itself is on the slower side.
Performance
14.3ns true latency at 5600MT/s CL40 is a modest result. Corsair's faster single RGB stick, CMH5X16G1B60C40A2 at 6000MT/s, delivers noticeably better latency for the same 16GB capacity.
Compatibility and Buying Advice
Buy this to match an existing 5600MT/s Vengeance RGB stick, or as a budget single-module RGB pick. For a new build, a matched RGB kit like CMH32GX5M2B6400C32 gives more reliable dual-channel operation and usually better timings.
