Compatible with Intel and AMD processors, features the latest XMP 3.0 technology. Used for 3 months, practically new. Reason for selling: I have 32GB and only need 16GB for my usage. Current offer is 550. Whoever offers more, even slightly, may God bless them with it. ATTENTION, PLEASE READ CAREFULLY: About 5 customers have approached me without paying attention that I am selling ONE stick with a capacity of ONLY 16GB. Some of you might think it's 16x2, which is incorrect. I am selling only one stick.
