Compatible Lenovo Thinkpad E450 upgrade

This 4 GB DDR3L SODIMM is built specifically for the Lenovo Thinkpad E450 laptop. It delivers 1600 MHz speed at 1.35 V with CL11 timing in a single 204-pin module. The stick is unbuffered, non-ECC and uses major-brand chips backed by a limited lifetime warranty from Computer Memory Solutions.

Suits owners adding one 4 GB stick.

Buyers wanting to add a single 4 GB module to an empty slot or replace a failed stick will find this a direct fit. Users who need a matched pair for dual-channel performance or who require the full 16 GB maximum capacity should look at a 2 x 8 GB kit instead. The 1Rx8 rank and 1.35 V operation match the factory specification exactly.

DDR3L 1.35 V voltage decides fit

The critical specification is the 1.35 V DDR3L voltage; standard 1.5 V DDR3 modules will not operate correctly in this system. Confirm the laptop requires low-voltage memory before ordering, as the 1600 MHz PC3L-12800 rating and 204-pin SODIMM form factor depend on that voltage.

商品問答

Will this 1.35V DDR3L SODIMM run stably in my ThinkPad E450 alongside an existing 1.5V DDR3 module?

The module operates at 1.35V DDR3L and is backward compatible with 1.5V DDR3 slots; the system will run both sticks at the lower voltage without issue.

How can I verify the CL11 1600MHz timing is active after installing the 4GB stick?

Open Task Manager or a tool like CPU-Z and confirm the memory shows 1600 MHz and 11-11-11 timings at 1.35V.

Does the single 204-pin stick come alone or with any installation hardware?

The package contains only the 4GB SODIMM module; no screwdriver, anti-static strap or additional parts are included.
