This is a kit of 2x8gb DDR3 SO-DIMM laptop RAM totaling 8GB. Both sticks are Silicon Power brand running at 1600MHz (PC3-12800) with CL11 latency at 1.35V. Both sticks were lightly used and have been tested before shipment. They are in fully working condition and ready to drop into your compatible laptop. This is a great budget option if you are looking to replace or upgrade your laptop's memory. I will only ship to the continental United States.
