16GB DDR4 2133MHz SODIMM for Dell XPS 15 9550

This Computer Memory Solutions module delivers 16GB of DDR4 memory at 2133MHz with CL15 timings. It uses a 260-pin SODIMM form factor and operates at 1.2V. The unbuffered, non-ECC design uses a 2Rx8 rank configuration with major brand chips.

Suits single-slot upgrades to 16GB

Builders needing 32GB total can install two of these sticks in the two available sockets. Users requiring ECC error correction or registered buffering should look elsewhere. Systems limited to lower voltages or different pin counts cannot use this module.

Fits directly into Dell XPS 15 9550 SODIMM slots

The 260-pin interface matches the laptop's memory sockets without adapters. Low-profile construction without a heat spreader clears tight chassis spaces. Single-stick packaging allows precise capacity planning for the two-slot platform.

Questions about this item

Does my Dell XPS 15 9550 need a free SODIMM slot for this 260-pin module?

The Dell XPS 15 9550 has two SODIMM sockets with a maximum capacity of 32GB, so a free slot is required to install this 16GB stick.

Will this DDR4 2133MHz CL15 memory downclock to match slower modules already installed?

Yes, DDR4 modules automatically run at the lowest common speed and latency, so this CL15 2133MHz stick will match slower DDR4 memory in the system.

How can I verify the 16GB stick is recognised at 2133MHz after installation?

Open Task Manager or BIOS on the XPS 15 9550; both will show 16GB capacity, DDR4 type and 2133MHz speed when the module is seated correctly.
