Computer Memory Solutions CM512648500SODRH 4GB DDR3 1066MHz CL7 SODIMM

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.
