Dell Latitude E6520 upgrade

This 4 GB DDR3L SO-DIMM is built for the Dell Latitude E6520 notebook. It runs at 1600 MHz with CL11 timing and operates at 1.35 V. The single 204-pin module adds 4 GB of unbuffered, non-ECC memory to the system.

Who this suits

It suits owners of a Latitude E6520 who need a straightforward 4 GB expansion. It does not suit buyers who need an 8 GB module or a two-stick kit for dual-channel bandwidth. It also does not suit anyone whose notebook requires 1.5 V DDR3 or a different pin count.

Deciding specification

The 204-pin DDR3L 1600 interface at 1.35 V decides fit. If the target machine accepts this exact voltage and pin layout, the module will work; otherwise it will not seat or run correctly.

Questions about this item

Will the 204-pin DDR3L SO-DIMM fit the memory slot in a Dell Latitude E6520?

Yes, the module uses the 204-pin SO-DIMM form factor specified for the Latitude E6520, so it seats directly into the notebook's memory socket without adapters.

What is the correct way to insert the stick so the 1.35 V DDR3L module is recognised at 1600 MHz?

Power off the notebook, remove the battery, open the memory door, align the notch on the 204-pin edge connector with the key in the slot, press firmly until both retention clips click, then reassemble and power on.

Does the 4 GB CL11 unbuffered module need any firmware update or periodic reseating to stay stable?

No firmware update is required; the JEDEC-standard 1.35 V DDR3L stick runs at 1600 MHz with 11-11-11 timings automatically, and it has no moving parts or heat spreader that would demand routine maintenance.
