16GB DDR5 4800 SODIMM Kit

This OWC kit supplies 16GB of DDR5 memory as two 8GB modules. Each stick runs at 4800 MT/s with CL40 latency at 1.1V. The 262-pin SO-DIMM form factor fits laptops, all-in-one PCs and compatible NAS units.

Suits DDR5 SO-DIMM slots only

The kit works in systems that accept non-ECC unbuffered DDR5 SO-DIMMs at 1.1V. Builders whose machines need ECC, registered DIMMs or a different pin count should look elsewhere.

4800 MT/s CL40 at 1.1V

The decisive specification is the JEDEC-standard DDR5 4800 speed with CL40 timing at 1.1V. If the platform requires a different data rate, latency or voltage this kit will not be compatible.

Questions about this item

Will the 262-pin DDR5 4800 SODIMMs fit the same slot as my current DDR5 memory?

Yes, the 262-pin form factor matches the standard DDR5 SO-DIMM slot used in compatible laptops, all-in-one systems and NAS units.

How can I verify the CL40 timing and 4800 MT/s speed are active after installation?

Open Task Manager or a system-information tool; the memory tab will show 4800 MT/s and the SPD data will report CL40 latency.

Does the dual-channel kit include only the two 8 GB modules or are tools and adapters supplied?

The box contains the two 8 GB DDR5 4800 CL40 SODIMM modules only; no screwdrivers, spacers or adapter brackets are included.
