Capacity and form factor

This is a 4GB DDR3 SO-DIMM module built to the 204-pin standard used in many laptops and all-in-one systems. It runs at 1333MHz with a CL9 latency and operates at the standard 1.5V for DDR3 memory. The stick is unbuffered, non-ECC and uses major-brand chips.

Compatibility fit

It suits owners of IBM-Lenovo systems that list part numbers 41R0635, 55Y3711, 55Y3717 or 64Y6652 as supported upgrades. Builders working on platforms that need registered or ECC memory should look at something else.

Deciding specification

The single detail that decides fit is the DDR3 1333MHz PC3-10600 rating combined with the 204-pin SO-DIMM form factor; if your machine requires a different speed, voltage or pin count this module will not work.

Questions about this item

My laptop currently has a 2 GB DDR3 SODIMM installed; can I run this 4 GB module alongside it?

The 4 GB stick runs at 1333 MHz CL9 1.5 V; if the existing module is also DDR3 SO-DIMM the system will operate both at the speed of the slower stick.

How can I confirm the 4 GB DDR3 1333 MHz module is running at its rated CL9 1.5 V after installation?

Open Task Manager or CPU-Z and check that the memory tab shows 4 GB, 1333 MHz, CL9 timings and 1.5 V.

What must my laptop already provide for this 204-pin DDR3 1333 MHz SODIMM to work?

A free 204-pin DDR3 SO-DIMM slot that accepts 1.5 V unbuffered non-ECC modules.
