System-Specific SODIMM for ThinkPad Edge E545

This 4 GB DDR3L SODIMM is built for the Lenovo ThinkPad Edge E545 notebook. It arrives as a single 204-pin module rated at 1600 MHz with CL11 timing and 1.35 V operation. The part is unbuffered, non-ECC and uses a 1Rx8 organisation.

Ideal for single-slot upgrades.

Owners with one free slot can add 4 GB instantly. The Edge E545 caps total memory at 8 GB across two sockets, so a second identical stick is required to reach the maximum or to enable dual-channel performance. Buyers needing more than 8 GB total should look elsewhere.

DDR3L 1600 MHz at 1.35 V

The decisive specification is the DDR3L 1600 (PC3L 12800) rating combined with 1.35 V voltage. Standard DDR3 modules at 1.5 V are not electrically compatible and will not work correctly in this platform.

Questions about this item

Does the 1.35V DDR3L module run cooler than standard 1.5V DDR3 during continuous use?

Yes, the lower 1.35V operating voltage reduces power draw and heat output compared with standard DDR3, helping the ThinkPad Edge E545 stay cooler during all-day workloads.

Will the 204-pin SODIMM fit directly into the ThinkPad Edge E545 without any extra brackets or adapters?

Yes, the 204-pin SODIMM form factor matches the notebook's memory slots exactly, so no additional hardware is needed for installation.

Can this 4GB 1600MHz stick work alongside an existing 4GB module to reach the 8GB maximum supported by the Edge E545?

Yes, the system supports up to 8GB across two sockets, so adding this 4GB DDR3L 1600MHz module to a matching 4GB stick will achieve the full capacity.
