Corsair CMH32GX5M2B6400C32 32GB (2x16GB) DDR5 Vengeance RGB Desktop RAM Kit Review
Need a fast 32GB DDR5 RGB kit for a gaming build? The Corsair CMH32GX5M2B6400C32 is a matched 2x16GB Vengeance RGB kit at DDR5-6400 CL32.
10.0ns true latency is a strong result for an RGB kit at this capacity — you're not paying a real performance penalty for the lighting compared to Corsair's fastest non-RGB 32GB kits.
Performance
10.0ns true latency at 6400MT/s CL32 matches Corsair's non-RGB CMK64GX5M2B6400C32 on timing (that kit is 64GB; capacity aside, the latency profile is identical), so this RGB kit isn't giving up anything on the performance side.
Compatibility and Buying Advice
6400MT/s sits right at the edge of AM5's 1:1 fabric ratio — check your board's QVL if this is going into a Ryzen 7000/9000 gaming build. Intel platforms handle it without concern.
