System-Specific Upgrade

This 4GB SODIMM is built for Dell Latitude E6420 and E6420 ATG notebooks. It uses 204-pin DDR3 technology rated at 1066MHz with CL7 timing. The module runs at 1.5V and is unbuffered and non-ECC. It installs directly into the factory memory slot.

Compatibility Profile

It suits owners of the listed Latitude models who need a single 4GB stick to replace a failed module or fill an empty socket. Buyers who want more storage or a different memory generation should look at something else. The part is not designed for desktop platforms or newer laptop architectures.

Deciding Specification

The 204-pin DDR3 1066MHz interface determines whether this module fits and functions. Only systems accepting PC3-8500 SO-DIMMs at 1.5V will recognise it correctly. Verify the notebook model before ordering.

Perguntas sobre este artigo

Does my Dell Latitude E6420 need an empty 204-pin SODIMM slot to install this module?

Yes, the module uses a standard 204-pin DDR3 SO-DIMM form factor, so an available SODIMM slot in the laptop is required.

Can I add this 4 GB stick to an existing 2 GB module for a total of 6 GB?

The system supports up to 8 GB across two sockets, but modules must be installed in matched pairs for dual-channel mode; mixing capacities will run in single-channel.

How can I confirm the memory is running at 1066 MHz with CL7 timing after installation?

Check the BIOS memory information or a tool such as CPU-Z; it should report DDR3-1066 (PC3-8500) with 7-7-7 timings at 1.5 V.
