System-specific DDR3 SODIMM kit

This 8 GB kit contains two 4 GB unbuffered DDR3 SO-DIMM modules built to the PC3-12800 1600 MHz standard with CL11 11-11-11 timings at 1.5 V. The 204-pin form factor matches the Dell Latitude E5420 notebook for which Computer Memory Solutions validates compatibility.

Suitable for E5420 owners needing 8 GB total

It suits anyone upgrading a Dell Latitude E5420 to the full 8 GB capacity using a matched pair. Builders working on any other laptop or desktop platform should look elsewhere because the module is qualified only for this specific system.

DDR3-1600 CL11 1.5 V specification

The single specification that decides fit is the DDR3-1600 CL11 1.5 V unbuffered SO-DIMM profile; a system requiring a different voltage, speed, latency or DDR generation will not accept these modules.

Questions about this item

Will the 204-pin DDR3 SODIMM modules fit the Dell Latitude E5420 notebook?

Yes, the 204-pin DDR3 SODIMM form factor matches the memory slots in the Dell Latitude E5420 notebook for which this kit is validated.

Which slot should I populate first when installing the two 4GB sticks?

Install the first module in the primary slot (usually labelled DIMM A or slot 0) before adding the second stick to the remaining slot.

Do these unbuffered non-ECC modules require any firmware updates or periodic cleaning?

No firmware updates are needed; the modules are maintenance-free, though occasional dust removal from the slot contacts with compressed air can help long-term reliability.
