Crucial CT32G56C46U5ES.M16B2 32GB Review
The Crucial CT32G56C46U5ES.M16B2 is a 32GB DDR5-5600 desktop module, another retail/vendor-suffix variant of Crucial's bare CT32G56C46U5 spec.
We'd shop this the same way as Crucial's other CT32G56C46U5 suffix listings, identical 32GB/5600MT/s/CL46 spec underneath.
Performance
5600MT/s CL46 computes to about 16.4ns true latency at plain JEDEC timings, matching every other CT32G56C46U5 variant Crucial sells under different suffixes.
Comparison to Alternatives
This is the same part as Crucial's CT32G56C46U5.M16D1 and CT32G56C46U5.C16D already in this catalog, price is the only real differentiator between the listings. For certified XMP/EXPO at the same spec, Crucial Pro CP32G56C46U5.C16B2 adds that plus a black heat spreader.
