DDR5 4800 SODIMM for Laptop and NAS

This OWC module adds 8GB of DDR5 memory running at 4800MHz with CL40 latency and a 1.1V operating voltage. The 262-pin SO-DIMM form factor fits laptops, all-in-one PCs and compatible NAS systems. It is an unbuffered, non-ECC design built to JEDEC standards.

Suits single-slot upgrades.

The single 8GB stick works well for owners filling one empty slot or replacing a failed module in a supported platform. Builders who need matched pairs, higher total capacity or ECC error correction should look at other configurations.

262-pin DDR5 interface decides compatibility

Only systems with a DDR5 SO-DIMM controller can accept this 262-pin module; older DDR sockets are physically and electrically different. Verify the platform specification before purchase.

Questions about this item

What real-world speed will this DDR5-4800 CL40 module run at in my laptop?

The module operates at 4800 MT/s with CL40 latency when the system supports that speed; if the platform only runs memory at a lower rate it will downshift automatically.

What does the PC5-38400 label on this SODIMM actually limit?

PC5-38400 is the JEDEC standard name for DDR5-4800 and defines the peak transfer rate the module is validated to deliver.

Will this 262-pin DDR5 SODIMM fit my laptop memory slot?

Yes, it uses the standard 262-pin DDR5 SO-DIMM form factor used in current laptops, all-in-ones and compatible NAS units.
