DDR4 2133 dual-channel kit

This OWC kit provides 8 GB of DDR4 laptop memory as two matched 4 GB modules. Each stick is a 260-pin SO-DIMM rated at 2133 MT/s with CL15 latency and 1.2 V operation. The kit is unbuffered, non-ECC and has no heat spreader.

Laptops and compact systems needing a simple upgrade

It suits notebooks, all-in-one PCs, mini desktops, micro servers and NAS units that accept standard DDR4 SO-DIMMs. Builders whose platforms demand registered or ECC memory, or who need a single higher-density module, should look elsewhere.

2133 MT/s CL15 DDR4 SO-DIMM specification

The decisive figure is the 2133 MT/s CL15 DDR4 SO-DIMM rating; the system must support this exact speed and latency combination. If the platform requires a different DDR4 speed grade or a different form factor, the modules will not function.

Questions about this item

Does this 260-pin DDR4 kit need a laptop slot that accepts 1.2 V modules?

Yes, each 4 GB module runs at 1.2 V, so the system must support that voltage for the kit to operate.

Will the CL15 timing of this 2133 MHz kit match older DDR4 sticks already in my machine?

The modules are CL15 at 2133 MHz; the memory controller will use the slowest timing present, so existing sticks with looser timings will set the pace.

How can I confirm the dual-channel kit is running at 2133 MHz after installation?

Open Task Manager or a tool like CPU-Z and check that the reported speed shows 2133 MHz and that both 4 GB modules are detected in dual-channel mode.
