Summary: I ordered G.Skill memory because of high recommendations. They're a great price and haven't had a problem. This order was a second one to max my iMac at 16 GB. For what it's worth, benchmarks I've ran say they're fast.
Summary: If your trying to figure out if this ram would work for your macbook pro yes it will, but from what i know it only works for mid 2009 and up. I paid $55 and raised my ram from 2gigs to 8 and now my Serato setup works fast.
Summary: Got these to upgrade a friend's computer from 4GB of RAM. Unfortunately, the original pair I got was DOA -- not the usual kind of memory error, but it would cause Windows to go into the blue screen of death every time.
Summary: Excellent replacement memory for my Sager/Clevo/XoticPC D900F laptop. Would easily buy this brand again, but wish they had had a deal on this in a 3-pack since the laptop only had 3 RAM slots.
Summary: My wife's laptop was having some performance issues with only 2GB of RAM installed. This was the cheapest quality RAM I could find that was compatible with the maximum specifications of her computer. The RAM was easy to install and she is no longer having performance issues during everyday use.
