Crucial RAM CT2K16G56C46S5 Review
Crucial RAM CT2K16G56C46S5 is a matched 32GB (2x16GB) DDR5-5600 CL46 dual-channel kit at plain JEDEC timings, the bare-bones counterpart to Crucial Pro for budget builders who want DDR5 capacity without paying for a heat spreader or XMP/EXPO certification.
Comparison to Alternatives
Against the Crucial Pro CP2K16G56C46U5 (identical 32GB/5600MHz/CL46 spec, plus heat spreader and dual XMP/EXPO certification), pick that kit if you want the certified overclock profile and better looks; choose this CT2K16G56C46S5 to save money when neither matters.
Speed and Latency
CL46 at 5600MT/s works out to 16.4ns of true latency (46 / (5600 / 2) x 1000). Almost every desktop DDR5 kit we list has a tighter true latency, so this is not a latency pick.
