Corsair CMP64GX5M4B6400C32 64GB Review
The Corsair CMP64GX5M4B6400C32 is a 64GB (4x16GB) DDR5-6400 CL32 quad-module kit from Corsair's Dominator Titanium RGB line.
10.0ns true latency at 6400MT/s CL32 is a strong result, and running it as a 4x16GB kit fills all 4 DIMM slots for 64GB total, useful if you need every slot populated rather than 2 larger sticks.
Performance
10.0ns true latency at 6400MT/s CL32 matches a well-tuned 6000MT/s CL30 kit, delivered here as a full 4-module 64GB kit.
Compatibility
Running 4 DIMMs at 6400MT/s is more demanding on the memory controller than an equivalent 2-module kit; check board QVL support.
Comparison to Alternatives
Corsair's own CMP64GX5M2B6400C32 reaches the same 64GB and speed using just 2 modules, an easier path to stable full-speed operation.
