What this module is and who it fits

This 8GB DDR4 SO-DIMM runs at 2666 MT/s with CL19 latency and uses the standard 260-pin layout for laptops. It suits owners of compatible notebooks or small-form-factor systems that accept DDR4 2666 memory and have a free SO-DIMM slot.

Installing it and common pitfalls

Installation requires opening the laptop chassis, locating the memory slot, and pressing the module in until the side clips lock. The usual issues are a slot already occupied, a BIOS that does not recognise the speed, or a platform limited to a lower maximum frequency.

Limits of the DDR4 2666 SO-DIMM standard

The DDR4 2666 interface caps transfer rates at 2666 MT/s, so faster modules will downclock to this speed. Total capacity is restricted by the number of slots and the platform's maximum supported memory, which this module alone does not define. Buyers needing more than 8GB per slot or speeds above 2666 MT/s must choose a different specification.
