Compatible DDR3 upgrade for Lenovo Ideapad Z570

This 4 GB DDR3 SODIMM is built for the Lenovo Ideapad Z570 series notebook. It delivers a straightforward memory increase for owners of that platform who need more capacity for everyday tasks. The module is unbuffered, non-ECC and uses a 204-pin SO-DIMM form factor that matches the laptop's slots.

204-pin SO-DIMM without heat spreader

The stick uses major-brand chips on a standard green PCB with no heat spreader, keeping the profile low enough for tight notebook chassis. Gold-edge contacts on the 204-pin connector ensure reliable insertion and removal during upgrades. Operating at 1.5 V, it draws the same voltage the original memory uses, so no BIOS voltage changes are required.

DDR3-1333 speed and dual-channel requirement

Rated at DDR3-1333 (PC3-10600) with CL7 7-7-7 timing, the module runs at the notebook's native memory bus speed. The Z570 platform requires modules to be installed in matched pairs to enable dual-channel mode; a single 4 GB stick will operate in single-channel configuration. The system maximum is 8 GB across two sockets, and a 64-bit operating system is needed to address the full capacity.

Questions about this item

What DDR3 speed and PC3 rating does this 204-pin SODIMM run at?

It operates at 1333 MHz with a PC3-10600 rating and CL7 7-7-7 timings at 1.5 V.

Will this single 4 GB stick fit the two SO-DIMM slots in a Lenovo IdeaPad Z570?

Yes, the 204-pin form factor matches the Z570 slots; the system accepts up to 8 GB total across both sockets.

Do I need to install a second identical module to enable dual-channel mode on the Z570?

The platform requires modules in matched pairs for dual-channel operation, so adding a second 4 GB stick is recommended.
