XPS 8950 memory upgrade

This 16 GB DDR5 module is built specifically for the Dell XPS 8950 desktop. It delivers a JEDEC-standard 4800 MT/s speed at CL40 latency and runs at 1.1 V. The single-rank 1Rx8 design fits the system's memory architecture without requiring ECC or registered buffers.

Unbuffered 288-pin DIMM

The stick uses a standard 288-pin unbuffered UDIMM form factor and has no heat spreader, keeping the profile low for tight chassis clearance. Installation is a straightforward DIY task that does not void the original system warranty. OWC tests every module in-house and backs it with a limited lifetime warranty and free technical support.

Verify slot count and maximum capacity

Before ordering, confirm how many DIMM slots your XPS 8950 has free and what total memory the motherboard and BIOS support. This module replaces Dell part numbers AB883074, AC027075, SNPG00XJC/16G and SNPK7G24C/16G. It is not suitable for systems that require ECC, registered memory or a different DDR generation.
