16GB Dual-Channel DDR5 SODIMM Kit

This OWC kit delivers 16GB of DDR5 memory in two matched 8GB modules. It runs at 4800 MT/s with CL40 timings at the standard 1.1V JEDEC voltage. The 262-pin SO-DIMM form factor targets laptops, all-in-one PCs and compatible NAS units.

Suits owners of DDR5-4800 SO-DIMM platforms

Builders upgrading a laptop, compact desktop or NAS that accepts 262-pin DDR5 SO-DIMMs at 4800 MT/s will find this kit a direct, compliant fit. Systems requiring ECC, registered modules, higher speeds, lower latencies or a different pin count cannot use this memory.

262-pin DDR5 SO-DIMM form factor decides fit

The single specification that determines compatibility is the 262-pin DDR5 SO-DIMM interface. Only platforms designed for this exact physical and electrical standard can accept the modules.

Questions about this item

What does the 4800 MT/s speed mean for everyday laptop use?

The kit runs at the JEDEC DDR5-4800 standard, so the memory controller can transfer data at up to 4800 million transfers per second without any manual tuning.

What does the PC5-38400 rating actually limit?

PC5-38400 is the JEDEC bandwidth designation for DDR5-4800; it defines the maximum theoretical throughput the modules are validated to deliver.

Will the 262-pin SODIMM modules fit my laptop’s memory slots?

Yes — each stick uses the standard 262-pin DDR5 SO-DIMM form factor used by current laptops, all-in-one PCs and compatible NAS units.
