Dual-Channel DDR4 Kit for Laptops and NAS

This OWC kit provides 16GB of DDR4 memory in two 8GB SO-DIMM modules. It runs at 2400MHz with CL17 latency at the standard 1.2V. The 260-pin form factor fits laptops, all-in-one PCs and compatible NAS units.

Suitable for DDR4 SO-DIMM Slots Only

The modules suit owners of laptops, mini desktops, micro servers or NAS devices that accept non-ECC unbuffered DDR4 SO-DIMMs. Builders needing ECC registered memory, DIMM form factors or a different DDR generation cannot use this kit.

Speed Rating Decides Compatibility

The PC4-19200 2400MHz CL17 specification determines whether the memory matches the host system. The kit is backwards compatible with 2133MHz operation, so it will downclock automatically if the platform requires the lower speed.

Questions about this item

How can I verify the 16GB dual-channel kit is running at 2400MHz CL17 after installation?

Open Task Manager on Windows or System Information on macOS and confirm the memory speed reads 2400MHz with CAS latency 17.

What is included in the box and do I need any extra parts to install the 2x8GB SO-DIMMs?

The box contains two 8GB 260-pin DDR4 SO-DIMM modules. No additional parts or tools are required for a standard laptop slot installation.

Should I choose this 16GB 2400MHz CL17 kit or a different capacity for my laptop upgrade?

Select this 16GB kit if your system supports DDR4 SO-DIMM and you want a matched dual-channel pair. Choose a different capacity only if your laptop has a single slot or a lower maximum memory limit.
