8GB DDR3 1066 kit for laptops

This Simmtec 8GB kit contains two 4GB DDR3 modules rated at 1066 MHz (PC3-8500). It is designed for notebook computers that accept DDR3 SO-DIMM memory. The matched pair enables dual-channel operation on compatible platforms.

Suits owners of older DDR3 notebooks.

This upgrade suits owners of DDR3-based laptops that support 1066 MHz memory and have two available SO-DIMM slots. It is not for systems that require a different DDR generation, nor for desktops that use full-size DIMMs, nor for laptops with soldered memory and no expansion slots.

Speed rating is the deciding specification

The 1066 MHz (PC3-8500) speed rating is the single specification that determines compatibility. The memory controller must support this exact data rate for the modules to function at their rated performance.
