8GB DDR4 2133 module for Dell XPS 8900

This 288-pin DIMM delivers 8GB of DDR4 memory at 2133 MHz with CL15 timings and 1.2V operation. It is built as a single 2Rx8 unbuffered non-ECC stick designed specifically for the Dell XPS 8900 desktop and Special Edition systems. The module uses major-brand chips and carries a limited lifetime warranty from the manufacturer.

Suits owners expanding a Dell XPS 8900 to 32GB

This upgrade fits buyers who need a guaranteed-compatible stick for the four-slot XPS 8900 platform. It is not for users requiring ECC error correction or registered buffering for server workloads. Builders working on any other motherboard or chassis should verify their exact model before purchasing, as this part is validated only for the listed Dell system.

Single-stick kit simplifies slot management

The package contains one 8GB DIMM, leaving three slots free for future expansion up to the 32GB system limit. No heat spreader is included, so the module relies on standard chassis airflow. There is no bundled software, RGB control or additional accessories; the value lies in the validated compatibility promise and the lifetime exchange warranty.

Questions about this item

My Dell XPS 8900 has four DIMM slots — does this 8GB stick leave room to reach the 32GB maximum?

Yes. The XPS 8900 supports up to 32GB across four slots, so this single 8GB module leaves three slots free for future upgrades.

Will this DDR4 2133 CL15 module run at its rated speed if I keep my existing 2133 MHz memory installed?

The module is rated DDR4 2133 (PC4 17000) CL15; when paired with identical speed memory the system will operate at 2133 MHz.

How can I confirm the new stick is recognised at 2133 MHz and CL15 after I install it?

Check the memory tab in CPU-Z or the BIOS — it should report 2133 MHz frequency and 15-15-15 timings for the new module.
