4GB DDR3L SODIMM for Dell Latitude

This 4GB DDR3L 1600 CL11 SODIMM module is built for Dell Latitude E6540, E7240, E7440 and E7450 notebooks. It delivers a straightforward capacity increase for users who need more headroom for everyday multitasking. The single-rank 1Rx8 design operates at 1.35V without ECC or a heat spreader.

Check your laptop before ordering

Confirm your model is one of the four listed Latitude systems and that a free 204-pin SODIMM slot is available. The board must accept DDR3L 1600 (PC3L-12800) at 1.35V with CL11 timing and unbuffered non-ECC operation. Mixing voltages, speeds or ECC types can prevent the system from posting.

Fits a standard memory upgrade

The module slides into the existing SODIMM socket and requires no extra cables, brackets or cooling. It draws power directly from the slot and leaves all other expansion ports untouched. Adding this stick frees up the remaining slot for a matching module if you want to run a dual-channel pair later.

Klausimai apie šią prekę

Does the OWC 4GB DDR3L 1600 module ship as a single stick or a kit, and are any tools required for installation?

The product consists of one 4GB DDR3L 1600 SODIMM. Installation is a DIY task that typically needs only a small screwdriver to open the laptop's memory compartment.

My Dell Latitude E7440 has two slots — should I buy one 4GB module or two for dual-channel performance?

For dual-channel operation on the E7440, purchase two identical 4GB modules. OWC recommends matching capacity, speed and manufacturer for optimal performance.

The listing shows PC3L-12800 and CL11 — what real-world speed will I see once the module is seated in an E6540?

The module runs at DDR3L 1600 with CL11 latency at 1.35V. The E6540's memory controller will operate it at that rated speed automatically.
