4 GB DDR3 1066 MHz SO-DIMM

This 204-pin unbuffered module adds 4 GB of DDR3-1066 memory to compatible Lenovo laptops. It runs at CL7 with 1.5 V and uses major-brand chips without a heat spreader. The single-stick kit is designed for straightforward notebook upgrades.

Compatibility and limits

It suits owners of IdeaPad Y550, Y560d, SL510 2847, ThinkPad Edge 14, Edge 15 and similar listed models who need non-ECC DDR3 SO-DIMM memory. It does not suit buyers who need ECC, registered DIMMs, a different DDR generation, a 260-pin form factor, or a module larger than 4 GB.

Deciding specification

The 1066 MHz DDR3 speed with CL7 timing and 1.5 V voltage is the single figure that determines whether this module matches the laptop's memory controller. Verify that the target system accepts PC3-8500 SO-DIMM before purchase.

Questions about this item

What laptop models does this 204-pin DDR3 SODIMM support?

This module is validated for Lenovo IdeaPad Y550, Y560d, SL510 2847, and ThinkPad Edge 14 and 15 series laptops.

Can I add this CL7 1066 MHz stick to an existing PC3-8500 module in the second slot?

Yes, it will run at the shared 1066 MHz speed and CL7 timing alongside another PC3-8500 SODIMM in the dual-socket platform.

How do I confirm the full 4 GB is active after installation?

Boot the laptop and check the system properties or BIOS memory summary; it should report 4 GB recognised on a 64-bit OS or up to the 32-bit limit.
