System-specific DDR5 SODIMM for Dell OptiPlex 7420

This 16GB DDR5 5600 CL46 module is built to the exact electrical and mechanical requirements of the Dell OptiPlex 7420 AIO and 7420 AIO Plus. It installs as a single 262-pin unbuffered non-ECC SODIMM running at 1.1V, delivering a JEDEC-standard PC5-44800 upgrade path for those all-in-one workstations.

Ideal for owners adding memory to a 7420 AIO.

The part suits anyone expanding a compatible OptiPlex 7420 AIO or 7420 AIO Plus where a factory-matched SODIMM is required. Builders working on standard laptops, desktops, NAS units or any system outside the named Dell models should look elsewhere because the module is validated only for those specific all-in-one configurations.

Fits the AIO SO-DIMM slot

The stick occupies one 262-pin DDR5 SO-DIMM socket inside the OptiPlex 7420 AIO chassis, leaving any additional slot available for a second module to reach higher total capacity. No heat spreader is fitted, so clearance matches the original Dell layout, and the 1.1V JEDEC voltage draws power within the system's standard memory budget.

Questions about this item

What Dell OptiPlex all-in-one models must I own for this 262-pin DDR5 SODIMM to work?

The module is validated for the Dell OptiPlex 7420 AIO and 7420 AIO Plus.

Will this CL46 DDR5 5600 module run stably alongside the original memory already installed in my OptiPlex 7420 AIO?

It operates at the standard JEDEC 5600 MT/s CL46 1.1 V profile, so the system will negotiate a common speed and timing with any existing DDR5 SODIMMs.

How can I confirm the 16 GB upgrade is recognised at 5600 MT/s after I seat the SODIMM?

Open Task Manager → Performance → Memory or run a tool like CPU-Z; the speed field should read 5600 MT/s and the total capacity should show the added 16 GB.
