Single 4 GB DDR3 SODIMM

This module is a 4 GB DDR3 1333 PC3-10600 CL9 2Rx8 204-pin 1.5 V non-ECC SODIMM built to JEDEC and RoHS standards. It is validated for Lenovo B470, B570, B570e, G470, G475, G570 and G575 notebooks and delivers a warranty-safe memory upgrade.

Ideal for listed Lenovo owners.

Owners of the named Lenovo B- and G-series models can install this stick to add 4 GB of DDR3 memory. Builders working on any other laptop, desktop, mini PC or NAS should look elsewhere because the SPD profile and physical keying are specific to those systems.

Fits a single DDR3 SODIMM slot

The module occupies one 204-pin DDR3 SO-DIMM socket and runs at the standard 1.5 V without requiring a heat spreader. It leaves any remaining slots free for additional identical modules if the platform supports more than one stick.

商品問答

Does my Lenovo G475 already need a free 204-pin SODIMM slot to add this 4GB module?

Yes, the module plugs into a single 204-pin DDR3 SODIMM slot, so one empty slot is required.

Can I keep the original PC3-10600 CL9 stick installed and add this 2Rx8 module beside it?

Both modules run at DDR3 1333 with CL9 timing and 1.5 V, so they can operate together in the same system.

How do I confirm the new 4GB module is recognised at PC3-10600 speed after installation?

The BIOS memory summary or Windows Task Manager will report 4 GB at 1333 MT/s for the added module.
