32GB DDR5 dual-channel kit

This OWC kit supplies 32GB of DDR5 memory in two 16GB unbuffered UDIMMs. It targets desktop, workstation, NAS and all-in-one owners who need a straightforward capacity increase. Modules run at the JEDEC-standard 4800 MT/s with CL40 timings and 1.1V operation. No heat spreaders or lighting are included.

288-pin UDIMM fits standard DDR5 slots

Each stick uses the 288-pin unbuffered DIMM form factor, so it drops into any desktop board wired for DDR5. The dual-channel pairing lets the memory controller interleave access across both modules. Non-ECC operation keeps compatibility simple for consumer platforms. No extra power connectors or cooling hardware are required.

Replaces Crucial CT2K16G48C40U5

The kit is validated as a direct replacement for the Crucial CT2K16G48C40U5 part number. It matches the same 4800 MT/s speed, CL40 latency, 1.1V voltage and 1Rx8 organisation. The upgrade is worthwhile when a system ships with less than 32GB or when older DDR5 modules run at lower data rates.

Questions about this item

Will a motherboard that only supports DDR5 4800 at 1.1V run this kit at its rated CL40 speed?

Yes, the kit is JEDEC-standard DDR5 4800 CL40 at 1.1V, so any board that runs DDR5 4800 at 1.1V will operate it at the rated timings without manual changes.

How hot do the bare modules get during an all-day compile or render workload?

The modules run at the standard 1.1V with no heat spreader, so thermals depend on case airflow; typical DDR5 UDIMMs at this voltage stay within JEDEC limits under sustained load.

Does my desktop need 288-pin DDR5 slots and a CPU memory controller that accepts 1Rx8 unbuffered non-ECC DIMMs?

Yes, the kit uses 288-pin unbuffered non-ECC DDR5 DIMMs in a 1Rx8 organisation, so the platform must provide DDR5 slots and a controller that supports that density and rank configuration.
