4GB DDR3 SODIMM for Dell Latitude

This 4GB DDR3 1066 CL7 SODIMM module upgrades select Dell Latitude laptops including the E4200 E4300 E4310 E5420m and E5520m models. The 204 pin 1.5V non ECC unbuffered design matches the factory specification for those systems. Installation is a straightforward DIY task for most users.

Suitable for owners of listed Latitude models

Buyers with other laptop models or desktop platforms should look elsewhere because the 204 pin SODIMM form factor and DDR3 1066 specification will not fit or function in different systems. Those needing ECC registered memory or higher capacities than 4GB per module also require a different product.

DDR3 1066 CL7 204 pin SODIMM specification

The speed grade PC3 8500 at CAS latency 7 is the single parameter that determines whether this module matches the memory controller in the supported Dell Latitude notebooks. Matching this exact rating ensures stable operation without downclocking or timing conflicts.

Questions about this item

Does the OWC 4GB DDR3 1066 SODIMM arrive as a single stick or do I need to buy anything else to install it?

The package contains one 4GB DDR3 1066 CL7 204-pin 1.5V SODIMM module. No additional parts are required for installation in a compatible Dell Latitude notebook.

My Latitude E4300 has two slots — should I choose this 4GB module or look for a different capacity?

This 4GB DDR3 1066 PC3-8500 CL7 2Rx8 SODIMM is validated for the Latitude E4300. If your system supports two modules you can install a second identical stick for 8GB total.

What does the PC3-8500 1066MHz rating actually deliver once the module is seated in my E5520m?

The module runs at DDR3 1066 with CL7 latency at 1.5V, giving the E5520m the standard JEDEC bandwidth and timing specified for that platform.
