I've read the review on the RAM for any type of PC. What I heard some complaints from customers that they experienced horrible service from Amazon. They receive some sort of incorrect packaging while others receive some sort of scam. For those had been scammed got their brand new item swapped with the old RAM.
Good thing I don't purchase any RAM from Amazon. I bought several pair of RAMs from 8 GB to 16 GB at Crucial.com aka legitimate department store.
