Dual-Channel DDR5 SODIMM Kit

This OWC upgrade kit delivers 16GB of DDR5 memory as two 8GB modules running at 4800MHz with CL40 latency. It uses the 262-pin SO-DIMM form factor and operates at the standard 1.1V. The kit is designed for laptops, all-in-one PCs and compatible NAS systems that support DDR5 SO-DIMM memory.

Suitable for DDR5 SO-DIMM Slots

Builders upgrading a laptop or all-in-one with an available DDR5 SO-DIMM slot pair will find this dual-channel kit a direct fit. Systems that require ECC or registered memory, need a different voltage, or only have a single SO-DIMM slot cannot use this kit. Buyers whose platforms do not support DDR5 SO-DIMMs should look elsewhere.

4800MHz CL40 DDR5 Speed Rating

The modules run at PC5-38400 (4800MHz) with a CAS latency of CL40 at 1.1V. This JEDEC-standard speed is the primary specification that determines whether the memory matches the system's supported memory controller settings. Verify that the target device accepts 4800MHz DDR5 SO-DIMMs before purchasing.

Questions about this item

Does my laptop need a DDR5 262-pin SO-DIMM slot to use this kit?

Yes, the modules are 262-pin DDR5 SO-DIMMs and only fit DDR5 laptop slots.

Can I keep one existing 8 GB module and add one stick from this kit?

The kit is a matched dual-channel pair; mixing capacities or speeds can prevent dual-channel operation.

How do I confirm the memory is running at PC5-38400 4800 MHz CL40 after installation?

Check the memory speed and timings in BIOS or a tool like CPU-Z; they should show 4800 MHz and CL40.
