System-Specific DDR3 SO-DIMM Kit

This 16 GB kit contains two 8 GB DDR3 1333 SO-DIMM modules built for the Lenovo ThinkPad Edge E420 1141. Each stick uses a 204-pin interface, runs at 1.5 V with CL9 timing, and is unbuffered non-ECC. The memory is validated for the listed model and backed by the manufacturer's lifetime warranty.

Suits Edge E420 owners maxing out both slots

It fits buyers who need the full 16 GB capacity supported by this laptop and want a matched pair for dual-channel operation. Builders working on any other notebook or desktop platform should look elsewhere because the module is qualified only for the specified ThinkPad.

204-pin DDR3 1333 SO-DIMM form factor

The 204-pin DDR3 SO-DIMM form factor is the single specification that decides fitment; systems requiring a different pin count, voltage or DDR generation cannot use these modules.

Questions about this item

Should I choose the 2 x 8 GB kit or look for a single 16 GB module?

The kit supplies 16 GB across two matched 8 GB SO-DIMMs, filling both slots in the ThinkPad Edge E420 1141 for dual-channel operation.

Will the 1333 MHz rating actually run at that speed once installed?

The modules are rated for DDR3 1333 (PC3 10600) at CL9 and 1.5 V; the Edge E420 1141 memory controller will run them at that speed.

Does the 204-pin SO-DIMM interface limit the upgrade in any way?

The 204-pin DDR3 SO-DIMM form factor matches the two slots in the Edge E420 1141, and the 16 GB total equals the system maximum.
