Corsair CMP32GX5M2B6400C32 32GB Review
The Corsair CMP32GX5M2B6400C32 is a 32GB (2x16GB) DDR5-6400 CL32 kit from Corsair's Dominator Titanium RGB line.
6400MT/s CL32 (10.0ns true latency) is a strong result right at the edge of AM5's comfortable range; most current-generation Ryzen boards run it fine at 1:1, though it's worth checking your board's QVL if you're on an older AM5 board.
Performance
10.0ns true latency at 6400MT/s CL32 matches a well-tuned 6000MT/s CL30 kit while adding extra bandwidth headroom.
Compatibility
6400MT/s is at the upper edge of what AM5 boards run at the efficient 1:1 fabric ratio; newer boards handle it comfortably, older ones may need to fall back to 6000MT/s.
Comparison to Alternatives
Against the equivalent Dominator Platinum RGB CMT32GX5M2X6400C38, this Titanium RGB kit has both the newer finish and a tighter CL32 rating versus CL38.
