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. (I was confused when Memtest86 originally showed no errors, but subsequent scans with the HP diagnostic and Memtest showed a fault.) I opened an RMA with GSkill, and they quickly replaced the defective RAM.
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.
