Computer Memory Solutions 32GB kit

This kit delivers 32 GB of DDR4 memory in a matched pair of 16 GB modules built to the 260-pin SO-DIMM standard. It runs at 2133 MHz with CL15 timings and 1.2 V unbuffered operation. Computer Memory Solutions guarantees compatibility with the listed system and backs the modules with a limited lifetime warranty.

Suits Alienware 15 R2 owners needing maximum RAM

The laptop accepts two SO-DIMM slots and supports up to 32 GB total, so this two-module kit fills every slot. Buyers who need ECC error correction, registered buffering, lower latency than CL15, or speeds above 2133 MHz cannot use this kit. The modules also lack a heat spreader, which may matter in thermally constrained chassis.

260-pin DDR4 2133 SO-DIMM form factor

These modules fit only DDR4 SO-DIMM sockets keyed for 260 pins at the 2133 MHz data rate. Systems requiring a different pin count, voltage, or memory generation will not accept them. Verify the laptop has two free slots before ordering.

Questions about this item

Should I choose the 32GB kit or a smaller capacity for my Alienware 15 R2?

The Alienware 15 R2 supports a maximum of 32GB across its two slots, so this 2x16GB kit fills the board completely and gives the largest supported capacity.

What does the 2133MHz speed mean once the modules are installed in the laptop?

The memory will run at DDR4 2133MHz with CL15 timings at 1.2V, delivering the rated bandwidth of PC4 17000 inside the Alienware 15 R2.

Is the 260-pin SODIMM interface the right one for the Alienware 15 R2, and does it limit the speed?

Yes, the 260-pin DDR4 SODIMM form factor matches the laptop's two slots, and the modules operate at their specified 2133MHz without downclocking.
