Corsair CMK5X16G1B52C40A2 16GB Review
Need a single 16GB DDR5 stick at a low, universally compatible speed? The Corsair CMK5X16G1B52C40A2 is a standalone Vengeance module running DDR5-5200 CL40.
5200MT/s CL40 trails every other single-module Vengeance stick in this catalog on latency, so this is really a fill-a-slot part rather than a performance pick.
Performance
15.4ns true latency at 5200MT/s CL40 is the slowest single-module 16GB option Corsair offers here, the 6000MT/s single sticks like CMK5X16G1B60C36A2 hit 12.0ns for the same 16GB capacity.
Compatibility and Buying Advice
5200MT/s runs without issue on any DDR5 platform, old or new. Buy this only to match an existing 5200MT/s stick, or if it's genuinely the cheapest 16GB single module available, otherwise a 6000MT/s single stick is the better pick at similar prices.
