Targeted Lenovo ThinkPad Upgrade

This 4 GB DDR3 SODIMM is built for owners of Lenovo ThinkPad Edge E120, E125, E325, E420, E420S and E520 models who need a straightforward memory increase. It arrives as a single unbuffered 204-pin module rated at 1333 MHz with CL7 timing and 1.5 V operation.

Not for non-listed laptops

Buyers with other notebooks should verify their exact model before purchasing, as this kit is validated only for the ThinkPad Edge series shown. It is also unsuitable for anyone requiring ECC error correction, registered buffering, or a dual-rank configuration beyond the 2Rx8 organisation supplied here.

1333 MHz DDR3 speed rating

The module runs at PC3-10600 (1333 MHz) with 7-7-7 latency, which is the decisive specification for matching the memory controller in the compatible Edge systems. Confirm that your laptop accepts this speed and voltage before ordering.

Questions about this item

Should I pick the 4 GB stick or look for a different capacity?

This module is a single 4 GB stick. If your laptop has two slots and you want 8 GB total, add a second identical stick. If only one slot is free, this 4 GB unit is the correct choice.

The box says 1333 MHz and 1600 MHz — which speed will I actually see?

The module is rated PC3-10600 at 1333 MHz with CL7 timing. The 1600 MHz figure is a separate manufacturer highlight; your system will run the stick at 1333 MHz unless the BIOS explicitly supports the higher speed.

Is the 204-pin SO-DIMM interface the limiting factor for bandwidth?

Yes. The 204-pin DDR3 SO-DIMM interface caps transfer rate at the module's 1333 MHz (PC3-10600) specification, so real-world throughput cannot exceed that ceiling.
