Compatible 4GB DDR3L SODIMM for Lenovo ThinkPad

This 4GB DDR3L module runs at 1600MHz with CL11 timing at 1.35V. It uses a 204-pin SO-DIMM form factor and is unbuffered, non-ECC memory. The single stick is built with major-brand chips and carries a limited lifetime warranty from Computer Memory Solutions.

Ideal for owners of ThinkPad X140E 20BLxxx

The kit suits users upgrading one of the two available slots in these specific Lenovo laptops. Buyers needing more than 4GB per module or requiring ECC error correction should look at other memory options. Systems that do not accept 204-pin DDR3L SODIMMs cannot use this part.

Maximum supported capacity is 8GB across two sockets

The laptop platform supports up to 8GB total memory using both SODIMM slots. This single 4GB stick fills one slot and leaves the second free for a matching upgrade. Installing a module larger than 4GB would exceed the documented per-slot limit.

Highlights

Questions about this item

What does the 1600 MHz rating mean once the module is installed in a ThinkPad X140E?

The module will run at 1600 MHz with CL11 timing at 1.35 V, delivering PC3L 12800 bandwidth in the X140E's memory slots.

How does the DDR3L 1.35 V specification affect compatibility with the X140E?

DDR3L at 1.35 V is the native voltage for the X140E; the module is unbuffered, non-ECC, 204-pin SODIMM and matches the system's electrical requirements.

Will this 204-pin SODIMM physically fit the X140E's memory sockets?

Yes, the 204-pin SODIMM form factor matches the two SO-DIMM slots in the ThinkPad X140E, and the module height is standard without a heat spreader.
