Upgrade for XPS 17 9720

This 8 GB DDR5 SODIMM is built for the Dell XPS 17 9720 and follows JEDEC PC5-38400 CL40 specifications. It targets owners who want more memory for multitasking or larger workloads without changing the factory voltage of 1.1 V.

Check slot count and current modules

The laptop uses 262-pin DDR5 SODIMM slots. Verify how many slots are free and whether existing memory matches the 4800 MT/s speed and CL40 timing so the new module can run at its rated specification.

Fits alongside factory memory

The unbuffered non-ECC 1Rx16 design works with the original Dell parts AB949333 and SNPMVK8PC/8G. Adding this stick increases total capacity while leaving any second slot available for a matching module later.

Soalan tentang produk ini

Does the 8 GB DDR5 4800 CL40 SODIMM arrive as a single stick, or do I need to buy a second module to reach 16 GB?

The upgrade consists of one 8 GB module. To reach 16 GB you would add a second identical stick, but the XPS 17 9720 also works with a single module.

My XPS 17 9720 has two SODIMM slots — should I choose this 8 GB stick or a 16 GB module for the first slot?

An 8 GB stick leaves the second slot free for a matching upgrade later, while a 16 GB module fills one slot immediately. Pick based on whether you prefer staged cost or maximum capacity now.

The spec lists 4800 MT/s and CL40 — what does that combination deliver in everyday use on the XPS 17 9720?

The JEDEC-standard 4800 MT/s rate with CL40 latency gives the memory controller its rated bandwidth and timing, so the laptop runs at its designed memory speed without manual tuning.
