16 GB DDR5 SODIMM for Inspiron 14 Plus 7420

This 16 GB DDR5 4800 CL40 module is built specifically for the Dell Inspiron 14 Plus 7420. It uses a 262-pin SODIMM form factor, runs at 1.1 V, and is unbuffered non-ECC with a 1Rx8 rank layout. The part replaces Dell part numbers AB949334 AC258275 SNPCYXXPC/16G SNPVNY72C/16G.

JEDEC compliance and warranty-safe upgrade

The memory meets JEDEC and RoHS standards, so it will not void the laptop warranty. OWC tests every module in-house and backs it with a limited lifetime warranty and free technical support. No extra software or accessories are included in the package.

Suits owners of the Inspiron 14

This single module suits anyone upgrading that exact model to 16 GB of DDR5 4800 memory. Buyers with a different laptop, a desktop, or a system that requires ECC or registered DIMMs should look elsewhere.

Questions about this item

Does the 16GB DDR5 4800 CL40 SODIMM need any future maintenance or replacement?

The module has no heat spreader and runs at standard 1.1V JEDEC voltage, so it requires no routine maintenance; it is designed to last the laptop's usable life.

What limit appears first when the 16GB DDR5 4800 SODIMM runs sustained workloads in the Inspiron 14 Plus 7420?

The single 16GB 1Rx8 rank caps total capacity at 16GB, so memory capacity is the first bottleneck before bandwidth or latency limits are reached.

How much heat or power does the 1.1V DDR5 4800 SODIMM generate during all-day use?

Operating at 1.1V without a heat spreader, the module draws minimal power and produces low heat suitable for thin-and-light laptop thermals.
