16 GB DDR5 SODIMM for Inspiron 16 Plus

This OWC module delivers 16 GB of DDR5 memory at 4800 MT/s with CL40 latency. It uses a 262-pin SODIMM form factor, runs at 1.1 V, and is built to JEDEC standards for the Dell Inspiron 16 Plus 7620 and 7630 models that have memory slots.

Suits owners of compatible Inspiron 16 Plus laptops

The single 1Rx8 rank design fits the factory slot count on these notebooks. Buyers who need ECC error correction, registered buffering, or a heat spreader should look elsewhere, as this module provides none of those features.

16 GB capacity for everyday multitasking

The 16 GB module handles typical workloads such as web browsing, office applications, and media playback with headroom to spare. Systems that demand more than 16 GB of total memory or faster speeds than 4800 MT/s will exceed what this single stick can provide.

Questions about this item

Does this 16 GB DDR5 module fit the two SODIMM slots in my Inspiron 16 Plus 7620 or 7630?

Yes, the 262-pin DDR5 SODIMM is built for those models and each slot accepts one module.

Will the 4800 MHz CL40 stick down-clock to match slower DDR5 already installed?

It will run at the lowest common speed and latency the memory controller sets for both modules.

How do I verify the module runs at 4800 MT/s CL40 after installation?

Open Task Manager or a hardware monitor and confirm the reported speed and timing match 4800 and CL40.
