2GB DDR3 SODIMM for ThinkPad Edge

This 2GB DDR3 1333 CL9 SODIMM is a single 204-pin 1.5V non-ECC module built to JEDEC standards. It targets owners of Lenovo ThinkPad Edge E120, E125, E220s, E320, E325, E420 and E420s laptops who need a straightforward memory increase.

Suitable for listed Edge models only

The module fits the specific ThinkPad Edge series named in the compatibility list. It is not for systems that require ECC, registered or higher-voltage memory, nor for machines limited to a different DDR generation or pin count.

Verify slot count and maximum capacity

Before ordering, confirm your laptop has a free SODIMM slot and check the manufacturer’s documented maximum supported memory per slot and in total. Match the existing module’s speed and voltage if you are adding to populated slots.

Questions about this item

Does this 204-pin DDR3 SODIMM need a free SO-DIMM slot in my ThinkPad Edge E120 to install?

Yes, the module plugs into a vacant 204-pin SO-DIMM socket; confirm your laptop has an open slot before purchasing.

Will the 1.5V 1333MHz CL9 timing work alongside any existing PC3-10600 stick already in my E320?

It matches the JEDEC PC3-10600 1333MHz CL9 1.5V spec, so it will run at the same speed and voltage as a compliant module already installed.

How can I verify the 2GB module is recognised at 1333MHz after fitting it in my E420s?

Open Task Manager's Performance tab or run CPU-Z; the memory section should show 2GB running at 1333MHz (PC3-10600) with CL9 timings.
