Dell XPS 8940 Memory Upgrade

This OWC module adds 16GB of DDR4 memory to a Dell XPS 8940 desktop. It runs at 3200MHz with a CAS latency of 22 and operates at the standard 1.2V. The 288-pin UDIMM fits the factory DIMM slots without modification.

Suitable for owners needing more capacity

The single 16GB stick suits users who have a free slot and want to increase total memory for multitasking or larger workloads. Buyers whose XPS 8940 already has all slots filled must remove an existing module first. Systems requiring ECC or registered memory cannot use this unbuffered non-ECC kit.

288-pin DDR4 UDIMM form factor

The module uses the standard 288-pin DDR4 UDIMM interface required by the Dell XPS 8940. It is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz speeds if the platform dictates a lower rate.

Questions about this item

Does the 16GB DDR4 3200MHz CL22 UDIMM ship as a single module or do I need to buy a second stick separately?

The product is a single 16GB 288-pin DDR4 UDIMM; add a second module only if your Dell XPS 8940 has a free slot and you want 32GB total.

Should I choose the 3200MHz CL22 version or a faster kit for my Dell XPS 8940?

The XPS 8940 officially supports up to 3200MHz; this CL22 module runs at that speed and will down-clock to 2933, 2666, 2400 or 2133MHz if the system requires it.

What does the 3200MHz PC4-25600 rating actually deliver once installed in the XPS 8940?

The module operates at 3200MT/s with CL22 latency at 1.2V, giving the maximum JEDEC-standard bandwidth the platform supports for a non-ECC unbuffered DIMM.
