OWC 4GB DDR3 1600 SODIMM

This module is a single 4GB DDR3 1600 PC3-12800 CL11 1.5V SODIMM built for Alienware M14x, M14x R2, M17x R4 and M18x notebooks. It suits owners of those models who want a straightforward capacity increase. It is not for buyers who need ECC error correction or registered buffering.

Installing the SODIMM

The stick uses a standard 204-pin DDR3 SO-DIMM form factor that fits the memory slot on the listed Alienware laptops. Most installations are a simple DIY task when you follow the maker's service guide. The main issues arise if the retention clips are not fully engaged or if the module is seated at an angle.

Check your Alienware model

Confirm the exact model name matches M14x, M14x R2, M17x R4 or M18x before ordering. Verify the factory memory runs at DDR3 1600 and 1.5V so the new module operates at its rated speed. Ensure the chassis has a free SO-DIMM slot for the upgrade.

Questions about this item

How can I verify the 4GB DDR3 1600 CL11 module is running correctly after installing it in my Alienware M17x R4?

The system BIOS or Windows Task Manager will show the new 4GB module at 1600MHz with CL11 timings and 1.5V operation.

What comes in the package and what extra parts are needed to complete the upgrade?

The box contains one 4GB 204-pin SODIMM module; no additional components or tools are required for installation.

Which capacity should I choose if my Alienware M14x R2 currently has 8GB installed in two slots?
