OWC 4GB DDR3 1600 SODIMM

This OWC module is a 4GB DDR3 1600 CL11 1Rx8 204-pin 1.5V Non-ECC SODIMM built for specific Dell Latitude notebooks. It targets owners of the Latitude 6430u, E5430, E5440, E5540 and E6230 who want a straightforward capacity increase.

DDR3 1600 CL11 interface limits

The DDR3 1600 PC3-12800 standard sets the maximum transfer rate and latency for this module. Systems that only support lower DDR3 speeds will run the memory at the slower rate, and platforms requiring ECC or registered DIMMs cannot use this unbuffered non-ECC stick.

Check your Latitude model and slot layout

Verify that your exact Latitude model appears in the supported list before ordering. Confirm the number of available SODIMM slots and the maximum memory per slot allowed by the BIOS, as some configurations restrict total capacity or require matched pairs. Buyers needing ECC, registered memory or capacities above 4GB per module should look elsewhere.

Questions about this item

Should I pick the 4GB module or a different capacity for my Latitude?

The listing shows a single 4GB SODIMM. If your model has two slots and you want 8GB, add a matching 4GB stick; if only one slot is free, this module gives you 4GB total.

What does the 1600 CL11 rating deliver in my laptop?

The module runs at 1600 MHz with CL11 latency at 1.5 V, matching the JEDEC DDR3 standard for the supported Latitude models.

Will the 204-pin DDR3 SODIMM fit and work in my E5440?

Yes, the 204-pin DDR3 SODIMM is the correct form factor for the E5440 and the other listed Latitude models.
