Compatible Lenovo ThinkPad upgrade

This 4GB DDR3L SO-DIMM is built for Lenovo ThinkPad E560, E565, Edge E145 and E460 notebooks. It runs at 1600 MHz with CL11 timing at 1.35V. The unbuffered, non-ECC module uses a 204-pin layout and 1Rx8 organisation.

Suits single-slot expansion only

Owners of the listed ThinkPad models who need a single 4GB stick will find guaranteed compatibility. Systems that require ECC, registered memory or capacities above 4GB per slot cannot use this module. Buyers with other laptop brands should verify specifications before ordering.

Voltage decides fit

The 1.35V DDR3L rating is the critical specification; the compatible ThinkPad platforms expect this low-voltage standard. A 1.5V DDR3 module will not meet the platform requirement. Confirm the system documentation calls for DDR3L before purchase.

Questions about this item

Should I pick the 4 GB stick or a larger kit for my ThinkPad E560?

The module is a single 4 GB SO-DIMM; add a second identical stick if your E560 has two slots and you want 8 GB total.

What does the 1600 MHz rating deliver in my laptop?

It runs at 1600 MHz with CL11 timing, giving the standard DDR3L bandwidth the E560 memory controller expects.

Will the DDR3L 1.35 V spec work in a slot that usually takes 1.5 V DDR3?

Yes — DDR3L is backward-compatible with 1.5 V DDR3 slots, so it fits the ThinkPad E560, E565, Edge E145 and E460 without voltage issues.
