Corsair CMK5X16G1B56Z36A2 16GB Review
The Corsair CMK5X16G1B56Z36A2 is another single-module DDR5-5600 CL36 Vengeance stick, sold under Corsair's "Z" part-number bin alongside the near-identical "C"-suffix CMK5X16G1B56C36A2 at the same rated speed and timing.
The Z-suffix and C-suffix versions run the same 5600MT/s CL36 spec, Corsair uses the different suffix to track a separate voltage/timing bin from manufacturing, not a different published speed grade, so functionally you should expect the same real-world performance from either.
Performance
12.9ns true latency at 5600MT/s CL36 puts this squarely in Corsair's budget DDR5 tier.
Compatibility and Buying Advice
AM5 handles 5600MT/s without any fabric-ratio penalty.
