Dell XPS 8900 and 8910 memory upgrade

This 8GB DDR4 module is built for Dell XPS 8900 and 8910 desktops. It runs at 2133MHz with CL15 timing at 1.2V. The 288-pin unbuffered non-ECC design matches the factory slot specification.

Replaces slower or smaller factory DIMMs

Swapping the original memory for this PC4-17000 stick raises bandwidth and capacity in a single step. The jump is worth it when the system still runs on the base configuration or when multitasking stalls on large files.

Suits owners of compatible Dell towers needing

Builders who need ECC, registered modules, higher speeds or larger single-stick capacities should look at something else. Systems outside the XPS 8900 and 8910 lines are not validated for this part.

Questions about this item

What motherboard slot does this 288-pin DDR4 UDIMM fit?

It fits a standard DDR4 288-pin DIMM slot on the Dell XPS 8900 or 8910 motherboard; the notch position matches the JEDEC DDR4 key so it only seats one way.

Which way round does the CL15 module go in, and what click confirms it is seated?

Align the off-centre notch with the slot ridge, press straight down until both side latches snap shut with an audible click — that click is the only confirmation the module is fully seated.

Will the 1.2 V, non-ECC 8 GB stick need a firmware update or heat spreader replacement later?

No firmware update is required; the module has no heat spreader to degrade and is validated to JEDEC 1.2 V specs, so it runs without further maintenance for the system's life.
