Lenovo ThinkPad E440 memory upgrade

This 4 GB DDR3L SODIMM is built for the Lenovo ThinkPad E440 notebook. It runs at 1600 MHz with CL11 timing and a low 1.35 V operating voltage. The single stick adds 4 GB of unbuffered, non-ECC memory to a compatible system.

Fits the two SODIMM slots in the E440

The module uses the standard 204-pin DDR3L form factor, so it installs directly into either of the notebook’s two memory sockets. No heat spreader is fitted, keeping the profile low for tight chassis clearance. The kit contains one stick, leaving the second slot free for a matching upgrade later.

Replaces slower DDR3 or fills an empty slot

Owners running a single 2 GB or 4 GB module at a lower speed will see the full 1600 MHz rate once this stick is seated. The jump is worth it when the E440 is used for multitasking or heavier workloads that exceed the current capacity. It does not suit systems that require ECC, registered DIMMs or a different DDR generation.

Questions about this item

Does the CL11 latency create a bottleneck during long workloads?

CL11 at 1600 MHz is the rated timing; sustained performance depends on the ThinkPad E440 memory controller and thermal limits.

How much heat does this 1.35 V DDR3L module produce when running continuously?

The low-voltage 1.35 V DDR3L design runs cooler than standard 1.5 V DDR3, and the unbuffered SODIMM has no heat spreader.

Will this 204-pin SODIMM work in my ThinkPad E440 without any other parts?

Yes, it installs directly into one of the two SODIMM slots; the notebook supports up to 16 GB total.
