Pros: They have great memory, run extremely fast

Cons: 1 of them stopped working for me after about 20 months and I didn't know what was wrong, I had blue screening, games wouldn't function and I thought it was a virus which infected my drivers and windows operating system. I realized it was bad when I tested it with one and it worked flawlessly. I wouldn't buy these for the simple fact of them being unreliable and all the work they put me through.

Overall Review: They worked for 20 months for me. Many other ram work way longer and are much more reliable. I would choose another brand even reading all of the other reviews about them.

Pros: none

Cons: no sata port

Overall Review: dont buy it other ones have sata ports for the same price.
