Corsair CMK5X32G2B52C40A2 32GB Review

The Corsair CMK5X32G2B52C40A2 is a single 32GB DDR5-5200 CL40 Vengeance module, one of Corsair's lower-speed single-stick DDR5 options.

5200MT/s CL40 is close to the DDR5 JEDEC floor, so this is a capacity-first, speed-second pick — 15.4ns true latency trails every other 32GB single stick Corsair sells in this catalog.

Performance

15.4ns true latency at 5200MT/s CL40 is the slowest 32GB single-module option in Corsair's Vengeance lineup here. If your platform supports 6000MT/s, CMK5X32G2B60C40A2 gives the same 32GB capacity with noticeably better latency for a modest price difference in most cases.

Compatibility and Buying Advice

5200MT/s is a safe, low-stress speed for any DDR5 board, including older or budget-tier motherboards that haven't been validated at higher speeds.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Best for

Budget or older DDR5 motherboards with limited speed validation
Maximum single-stick capacity when speed isn't the priority

Not for

Builds where memory bandwidth matters — the 6000MT/s single stick is a better pick
New dual-channel builds — buy a matched kit
