OWC 8GB DDR5 4800 SODIMM for Inspiron 16 Plus

This OWC module is an 8GB DDR5 4800 PC5-38400 CL40 1Rx16 262-pin 1.1V non-ECC SODIMM. It is built for Dell Inspiron 16 Plus 7620 and 7630 laptops that have user-accessible memory slots. The part replaces Dell part numbers AB949333 and SNPMVK8PC/8G. It is a new, JEDEC-standard component tested to meet OEM specifications.

Single-slot 8GB capacity at DDR5 4800 speed

The key specification is the single 8GB capacity running at DDR5 4800 with CL40 latency. This density fits one 262-pin slot and operates at the standard 1.1V. Buyers needing more than 8GB per slot or a different DDR generation must choose another module, as this part only provides this exact capacity and speed combination.

Drop-in upgrade for compatible Inspiron 16

Installation uses the existing SODIMM slot in supported Inspiron 16 Plus 7620 and 7630 units with memory slots. The unbuffered, non-ECC design requires no configuration changes. It frees the system to run more applications and larger files simultaneously. Systems without accessible slots or those requiring ECC or registered memory cannot use this module.

Questions about this item

What does the 4800 CL40 rating mean for real-world laptop performance?

The module runs at the JEDEC-standard 4800 MT/s with CL40 latency, giving the Inspiron 16 Plus 7620 or 7630 a stable, warranty-safe speed boost for multitasking and larger files.

How does the PC5-38400 DDR5 SODIMM interface limit the upgrade?

The 262-pin DDR5 SODIMM slot caps the memory at 4800 MT/s and 1.1 V, so this 8 GB stick operates at the platform's maximum supported data rate without overclocking.

Will the 262-pin 1Rx16 stick fit the Inspiron 16 Plus memory slot?

Yes — it matches the factory 262-pin SODIMM form factor, 1.1 V voltage and single-rank 1Rx16 layout used in the 7620 and 7630 models with memory slots.
