16 GB DDR4 SODIMM for Alienware 15 R3

This 16 GB module upgrades the Alienware 15 R3 laptop with DDR4 memory. It runs at 2133 MHz with CL15 timing and 1.2 V operation. The stick suits users who need more capacity for multitasking or memory-hungry applications on that specific notebook.

260-pin unbuffered design fits the factory slots

The module uses a standard 260-pin SO-DIMM form factor with unbuffered, non-ECC chips in a 2Rx8 configuration. No heat spreader is fitted, keeping the profile low for the laptop’s tight slot spacing. One stick ships in the package, leaving the second slot free for a matching upgrade later.

Low voltage and standard timings keep thermals mild

At 1.2 V the RAM draws minimal power, so it adds little heat inside the chassis. CL15 latency at 2133 MHz runs within JEDEC limits, meaning the memory controller does not need extra voltage or aggressive fan curves. Normal workloads stay quiet and cool without special tuning.

Questions about this item

What DDR4 speed does this 2133 MHz SODIMM run at in the Alienware 15 R3?

The module operates at its rated 2133 MHz DDR4 speed; the Alienware 15 R3 memory controller supports this frequency natively.

Will the 260-pin SO-DIMM fit the two memory slots in my Alienware 15 R3?

Yes, the 260-pin DDR4 SO-DIMM form factor matches both slots in the Alienware 15 R3, which accepts up to 32 GB total.

How do I install the stick, and what step do people often miss?

Power off, unplug, open the bottom panel, insert the module at an angle until the gold contacts disappear, then press down firmly until both side clips click — many forget the final click.
