System-specific DDR5 upgrade for Dell XPS 8950

This 8GB OWC module is built to JEDEC standard DDR5 4800 CL40 timing at 1.1V. It uses a single-rank 1Rx16 layout on a 288-pin unbuffered non-ECC UDIMM. The part number 4U8D51R608GB replaces Dell part numbers AB883073 and SNP29NJ4C/8G for a warranty-safe installation.

Suits owners adding capacity to an XPS 8950.

Builders working on any system other than the Dell XPS 8950 should look elsewhere because this module is validated only for that model. Buyers needing ECC error correction or registered buffering must choose a different specification. The stick has no heat spreader, so users expecting one should consider other options.

8GB single-module capacity decides the fit

The kit provides exactly 8GB in one DIMM, so the total memory after installation depends on how many slots the XPS 8950 has free and what the board's maximum supported capacity per slot allows. Check the system documentation for the slot count and per-slot limit before purchasing.

Questions about this item

Should I pick the single 8 GB module or add a second stick for dual-channel?

The kit is one 8 GB DDR5 4800 CL40 UDIMM; adding a matching module enables dual-channel bandwidth on the XPS 8950.

What does the 4800 MT/s rating deliver in the XPS 8950?

The module runs at JEDEC 4800 MT/s CL40, giving standard DDR5 throughput for everyday multitasking in the XPS 8950.

Is the 288-pin DDR5 interface limited by the XPS 8950 memory controller?

The 288-pin DDR5 UDIMM connects directly to the XPS 8950 controller at 4800 MT/s with no further bottleneck.
