32 GB DDR4 UDIMM for Dell XPS 8940

This 32 GB DDR4 3200 MHz module is built specifically for the Dell XPS 8940 desktop. It installs as a single 288-pin unbuffered DIMM running at 1.2 V with CL22 latency. The JEDEC-compliant design ensures a warranty-safe upgrade without configuration changes.

Suits XPS 8940 owners only; not for other systems

The module targets Dell XPS 8940 users who need more memory for multitasking or larger workloads. Builders working on different motherboards, laptops or servers should look elsewhere because the part is validated only for that specific desktop platform.

3200 MHz CL22 speed grade decides fit

The decisive specification is the 3200 MHz CL22 JEDEC rating. The XPS 8940 memory controller will run this stick at its rated speed and latency; systems requiring a different speed bin, lower latency or ECC functionality cannot use this module.

Questions about this item

What free DIMM slots must the Dell XPS 8940 have to install this 288‑pin UDIMM?

The XPS 8940 needs one or more empty 288‑pin DDR4 UDIMM slots; this module occupies a single slot.

Will this CL22 3200MHz module run with existing 2133MHz, 2400MHz, 2666MHz or 2933MHz DDR4 sticks?

Yes, it is backward compatible and will operate at the speed of the slowest installed module.

How can I confirm the system recognises the full 32GB at 3200MHz CL22 after fitting the module?

Check the BIOS memory info or Windows Task Manager — both should show 32GB, 3200MHz and CL22 timings.
