OWC 4GB DDR3 module for HP Pro 3420 AIO

This OWC memory module adds 4GB of DDR3 capacity to the HP Pro 3420 all-in-one desktop. It is built for owners of that specific system who want a straightforward capacity increase without configuration changes.

204-pin SODIMM fits the integrated slot

The module uses the 204-pin SODIMM form factor required by the all-in-one chassis. It operates at 1.5V with CL9 latency and is unbuffered non-ECC, matching the platform's electrical requirements. No heat spreader is fitted, keeping the profile slim for the compact internal space.

4GB single rank suits light multitasking

The 4GB density handles everyday office applications, web browsing and document editing comfortably. Heavier workloads such as large media projects or virtual machines will exceed the available headroom, so users needing more capacity should verify the maximum supported configuration before purchasing.
