Crucial CT16G56C46U5.M8D1 16GB DDR5 Desktop RAM Module Review

The Crucial CT16G56C46U5.M8D1 is a 16GB DDR5-5600 desktop module from Crucial's bare RAM line, no heat spreader, no XMP profile.

We'd recommend it as a single-stick 16GB desktop upgrade when you don't need dual-channel bandwidth or a certified overclock, it's the plain version of the same silicon Crucial sells under its Pro badge.

Performance

5600MT/s CL46 is one of Crucial's most common DDR5 desktop speed bins, true latency works out to about 16.4ns at plain JEDEC timings with no XMP or EXPO profile to enable.

Comparison to Alternatives

Crucial's own Pro-badged CP16G56C46U5 uses the identical 16GB/5600MT/s/CL46 spec with dual XMP 3.0/EXPO certification and a heat spreader for a bit more money; pick that one if certified one-click overclocking matters to you. For dual-channel setups, Crucial RAM's own CT2K16G56C46S5 SODIMM kit or the Crucial Pro CP2K16G56C46U5 desktop kit split the same capacity across two modules instead.
