16GB DDR4 SODIMM for Alienware Alpha R2

This 16GB DDR4 2133MHz SODIMM is built specifically for the Alienware Alpha R2 compact desktop. It provides a direct memory upgrade for owners of that system who need more capacity for multitasking and larger workloads.

JEDEC-compliant 260-pin unbuffered module

The stick follows JEDEC standard specifications at 1.2V with CL15 latency and a 2Rx8 rank configuration. Its 260-pin SO-DIMM form factor fits the Alpha R2 slot without a heat spreader, keeping installation straightforward inside the small chassis.

Replaces lower-capacity factory memory

Swapping the original module for this 16GB kit raises the system ceiling for simultaneous apps and large files. The jump is worthwhile when the current amount forces frequent paging or limits the number of browser tabs and creative projects you can keep open.

Questions about this item

Does the DDR4 2133MHz PC4-17000 CL15 module run at the full 2133MHz speed inside the Alienware Alpha R2?

The module is rated for DDR4 2133MHz PC4-17000 CL15; the Alpha R2 memory controller will operate it at up to that speed, limited by the platform's maximum supported frequency.

What physical slot and clearance does the 260-pin SODIMM need inside the Alpha R2?

It requires a standard DDR4 260-pin SO-DIMM slot; the stick has no heat spreader, so it fits the low-profile socket used in the Alpha R2 without clearance issues.

How is the SODIMM installed in the Alpha R2, and what step is often missed?

Power off and unplug the system, open the chassis, align the notch on the module with the key in the slot, insert firmly until seated, then press down until the side retention clips lock automatically.
