Alienware M18X R2 memory kit

This 16 GB kit contains two 8 GB DDR3L SO-DIMMs built for the Alienware M18X R2 notebook. Each module runs at 1600 MHz with CL11 timing at 1.35 V. The unbuffered, non-ECC design matches the factory specification for this system.

Suits owners upgrading an M18X R2

The kit fills two of the four available slots and works with a 64-bit operating system. Buyers who need the full 32 GB maximum capacity must add another identical pair. Systems limited to 32-bit operating systems cannot address the full 16 GB provided here.

Handles multitasking and heavier workloads

Two ranks per module (2Rx8) give the memory controller more open pages for parallel requests. The 16 GB total covers modern browsers, creative suites and virtual machines. Workloads that exceed 16 GB will page to storage, and the platform cannot accept more than 32 GB in total.

Questions about this item

Does the Alienware M18X R2 need a 64-bit operating system to use all 16 GB of this DDR3L kit?

Yes, the notebook's maximum 32 GB configuration across four sockets requires a 64-bit OS, so the full 16 GB from this 2 x 8 GB kit will only be recognised on a 64-bit installation.

Can I keep the original DDR3L 1600 modules already in my M18X R2 and add this 2 x 8 GB kit to reach the 32 GB limit?

The M18X R2 has four 204-pin slots and supports up to 32 GB total; adding this 16 GB kit alongside existing DDR3L 1600 sticks works as long as combined capacity does not exceed 32 GB and all modules run at 1.35 V CL11.

How can I confirm the kit is running at the rated 1600 MHz and CL11 timings after installation?

Open Task Manager's Performance tab or run CPU-Z; the memory section should show 1600 MHz speed and 11-11-11 timings matching the module's PC3L-12800 specification.
