I ordered two to upgrade my laptop seems to have done the job. It wasn't a huge bottleneck on my computer so I didn't see much of an improvement, went from 4GB to 8GB just to try and squeeze another year out of my old laptop. One of the pair I ordered was made in Korea. and the other in China, and one was built in 2014 and the other in 2015. It probably doesn't matter, but it's still weird.
