Corsair CMK5X16G1B60Z40A2 16GB Review

The Corsair CMK5X16G1B60Z40A2 is a single 16GB DDR5-6000 CL40 Vengeance module, running at the AM5 sweet-spot speed but with looser CL40 timings.

6000MT/s is the right speed target for AM5, but CL40 leaves latency on the table compared to Corsair's CL36 single sticks (CMK5X16G1B60C36A2) at the identical 6000MT/s speed and 16GB capacity.

Performance

13.3ns true latency at 6000MT/s CL40 trails the CL36 single sticks (12.0ns) at the same speed and capacity.

Compatibility and Buying Advice

6000MT/s still lands at the AM5 1:1 fabric ratio regardless of CAS latency, so there's no compatibility downside here, only a latency one.
