System-Specific DDR4 for Alienware Aurora R5

This 4GB DDR4 module is built to OWC part number 2U1D41R804GB and validated for the Alienware Aurora R5 desktop. It targets owners of that platform who need a straightforward capacity increase without compatibility guesswork.

JEDEC-compliant unbuffered UDIMM

The stick uses a standard 288-pin unbuffered layout at 1.2V with no heat spreader, so it seats directly in the Aurora R5’s DIMM slots. CL15 timing at 2133MHz follows the PC4-17000 JEDEC profile, ensuring the system recognises the module at its rated speed without manual configuration.

Low-voltage operation for quiet thermals

At 1.2V the module draws minimal power, producing little extra heat inside the chassis. The absence of a spreader keeps the profile slim, allowing unrestricted airflow from the existing case fans. Acoustic impact is negligible during typical workloads.

Questions about this item

What speed does the DDR4 PC4-17000 rating actually deliver?

The module runs at 2133 MHz with CL15 timings at the standard 1.2 V JEDEC voltage.

Will this 288-pin UDIMM fit the Alienware Aurora R5 motherboard slots?

Yes — it is a 288-pin unbuffered non-ECC DIMM built specifically for the Aurora R5.

What is the correct way to seat the module so the Aurora R5 recognises the full 4 GB?

Align the notch with the slot key, press straight down until both retention clips click, then verify 4 GB appears in BIOS.
