OWC 8GB DDR5 4800 SODIMM for Inspiron 14 Plus 7420

This OWC module is an 8 GB DDR5 4800 CL40 SODIMM built for the Dell Inspiron 14 Plus 7420. It runs at 1.1 V as an unbuffered, non-ECC 1Rx16 part with 262 pins. The upgrade is JEDEC and RoHS compliant and replaces Dell part numbers AB949333 and SNPMVK8PC/8G.

Who this suits and who it does not

It suits owners of the Inspiron 14 Plus 7420 who want a single 8 GB DDR5 stick to add capacity or replace a failed module. It is not for systems that require ECC or registered memory, nor for buyers who need a higher total capacity than one 8 GB module provides.

The specification that decides fit

The module is a 262-pin DDR5 SODIMM rated at 4800 MT/s with CL40 latency at 1.1 V. If the laptop demands a different pin count, voltage, DDR generation or form factor, this part will not work.
