Capacity and form factor

This OWC module provides 32 GB of DDR5 memory in a 262-pin SO-DIMM package. It operates at 4800 MT/s with a CAS latency of CL40 and runs at the standard 1.1 V. The stick is unbuffered, non-ECC and has no heat spreader, making it a direct drop-in for compatible laptops, all-in-one PCs and NAS units.

Who this suits and who it does not

The module suits owners of systems that accept a single 32 GB DDR5 SO-DIMM at JEDEC 4800 speeds. Builders who need ECC error correction, registered buffering, lower latency timings or a different voltage should look elsewhere. Systems that only support smaller per-slot capacities or a different pin layout will not be compatible.

Deciding specification

The 262-pin DDR5 SO-DIMM form factor combined with 4800 MT/s JEDEC timing is the single specification that determines fit. If the target device requires this exact pin count, voltage and speed grade, the module will work; otherwise it will not seat or boot.

Questions about this item

Does the 262-pin DDR5 SODIMM arrive as a single 32 GB stick or do I need to buy anything else?

The module is a single 32 GB 262-pin DDR5 SODIMM; no extra parts or cables are required for installation.

I see CL40 and 4800 MHz listed — which spec should I match when choosing a module?

Match both the 4800 MHz speed (PC5-38400) and the CL40 latency; this module meets the JEDEC standard for that combination.

What does the 4800 MHz rating actually deliver once the stick is seated in a laptop?

The 4800 MHz rating sets the maximum JEDEC data rate; the system will run at that speed if the CPU and chipset support DDR5-4800, otherwise it will down-clock to the highest supported speed.
