System-Specific DDR4 Kit

This 16 GB kit contains two 8 GB DDR4 DIMMs rated at 2133 MHz with CL15 timings. The modules are unbuffered, non-ECC and run at 1.2 V. Computer Memory Solutions validates compatibility for the Alienware Area 51 R2 desktop and Aurora R5 series. Each stick uses a 288-pin interface and a 2Rx8 rank configuration.

Builders Upgrading Compatible Alienware Desktops

The kit suits owners of the listed Alienware models who want to populate two of the four available slots. Buyers with a different motherboard or a platform that requires registered memory should look elsewhere. Systems needing ECC error correction or a higher-speed grade are also not addressed by this part.

DDR4 2133 CL15 Specification

The decisive figure is the 2133 MHz speed combined with CL15 latency at 1.2 V. If the target board demands a different data rate or timing, the modules will not operate as intended. Matching this exact rating is the single check that confirms the upgrade will work.

Questions about this item

Does my Alienware Area 51 R2 need all four DIMM slots filled to run this 16 GB kit?

The Area 51 R2 has four slots and supports up to 64 GB, so this 16 GB kit works in two slots without filling the board.

Will the 2133 MHz speed and CL15 timings match the original Aurora R5 memory?

Aurora R5 systems shipped with DDR4 2133 CL15, so this kit runs at the same speed and latency as the factory modules.

How can I confirm the kit is running at 2133 MHz with 15-15-15 timings after installation?

Open Task Manager or CPU-Z and verify the memory frequency shows 2133 MHz and the timings read 15-15-15 at 1.2 V.
