Compatible Dell XPS 15 17 memory

This 64 GB kit uses two 32 GB DDR5 SODIMM modules built for Dell XPS 15 and XPS 17 laptops. It targets users who need the maximum supported capacity for demanding workloads on these specific machines.

262-pin DDR5 SODIMM form factor

The modules fit the 262-pin DDR5 SODIMM slots found in the compatible Dell models. Non-ECC unbuffered operation at 1.1 V matches the platform requirements, and the 2Rx8 organisation is validated for stability in these systems.

64 GB at DDR5 4800 CL40

The kit delivers 64 GB total capacity running at 4800 MT/s with CL40 latency. This headroom handles large datasets, virtual machines and heavy multitasking, while the fixed speed and latency define the performance ceiling for these laptops.

Questions about this item

Will the 2Rx8 DDR5 SODIMM modules need any firmware updates or re-seating over time?

No firmware updates are required; the modules are unbuffered non-ECC DDR5 SODIMMs that remain seated unless physically disturbed.

What limits sustained throughput first — the CL40 latency or the 4800 MT/s data rate?

The 4800 MT/s data rate sets the bandwidth ceiling; CL40 latency affects response time but does not cap sustained throughput.

How much heat or power will the 1.1 V 64 GB kit add during all-day workloads?

At 1.1 V the kit draws minimal power and runs cool without a heat spreader, adding negligible heat inside a Dell XPS 15 or 17 chassis.
