Compatible ThinkCentre AIO Models

This 4GB DDR3 SODIMM is built for Lenovo ThinkCentre Edge 71z, Edge 91z, M70z, M71z and M90z all-in-one systems. It suits owners who need a single module to add capacity or replace a failed stick in those machines. Buyers with other desktop or laptop platforms cannot use this memory.

Installation Notes

The module uses a standard 204-pin SODIMM slot and requires no tools beyond opening the AIO chassis. Because it is unbuffered non-ECC at 1.5V, it drops in without BIOS changes on the listed models. The main risk is ordering it for a system that takes a different DDR generation or a DIMM form factor.

Pre-Order Checks

Confirm your ThinkCentre model number matches one of the five compatible AIOs before ordering. Verify the board has a free SODIMM slot and that the existing memory runs at DDR3 1333 PC3-10600 CL9 so the new module will operate at its rated speed.

Questions about this item

How can I confirm the 4GB DDR3 1333 CL9 module is running at PC3-10600 speed after installing it in my ThinkCentre Edge 71z AIO?

Open Task Manager or BIOS and verify the memory reads 1333 MHz, CL9 timings and 1.5 V on the 204-pin SODIMM slot.

What does the OWC 1S3D32R804GB kit include and do I need any extra parts for the M90z AIO?

The box contains one 4GB 2Rx8 unbuffered non-ECC SODIMM; no additional components or tools are required for installation.

Should I choose the single 4GB 2Rx8 stick or add a second identical module for my M71z AIO?

Adding a second matching 4GB 2Rx8 module enables dual-channel operation and doubles capacity to 8GB.
