Compatible Lenovo C440 memory upgrade

This 4 GB DDR3 SODIMM is built to work with Lenovo Essential C440 series notebooks. It installs in a 204-pin slot and runs at 1600 MHz with CL11 timing. The module is unbuffered and non-ECC, matching the factory specification for these systems.

Suits owners adding or replacing RAM in a C440

Buyers who need more than 4 GB per slot or who want ECC protection should look elsewhere. The board accepts a maximum of 8 GB across two slots, so a single 4 GB stick fills half that capacity. Systems requiring registered memory or a different pin count are not compatible.

Runs at 1.35 V DDR3L voltage

The stick operates at the lower 1.35 V DDR3L level rather than standard 1.5 V DDR3. This voltage match is the critical detail that decides whether the module will post reliably in the target Lenovo models.

أسئلة حول هذا المنتج

Does the 1.5 V or 1.35 V module run warm during continuous use?

The module operates at 1.5 V or 1.35 V DDR3L voltage without a heat spreader; typical SO-DIMM power draw is low, so temperatures stay modest inside a notebook chassis.

Must the Lenovo Essential C440 have a free 204-pin SO-DIMM slot to install this stick?

Yes, the C440 provides two 204-pin DDR3 SO-DIMM slots and supports up to 8 GB total, so at least one slot must be free for this 4 GB module.

Will this DDR3-1600 CL11 stick down-clock to match slower memory already installed?

DDR3 SO-DIMMs negotiate a common speed at boot; the module will run at the highest frequency both sticks and the memory controller support.
