This RAM is exactly the same as the 8GB ddr4 in my Alienware. I bought from A-Tech and it was Hynix China not Korea but don't worry the RAM in my Alienware was also Hynix China so the country doesn't matter just make sure the model and specs are the same . The RAM looked fairly new apart from some faded letters on the chip itself, but that didn't matter at 40, it was a huge improvement. The laptop was faster, more responsive and the stuttering common to some more modern games (Cod Warzone) was completely gone. I really like having 16GB RAM in dual channel mode. I definitely recommend the update!
