Pros: Great Memory on paper, computer runs very quickly when it is not crashing...

Cons: Currently does not appear to have great compatibility with a new iMac. When I added 32GB to a Late 2013 iMac i7 3.5 ghz/4GB 780 M video/3tb fusion drive I constantly have kernel panics and restarts which disappear when I switch back to stock ram. Beware of Newegg's restock policy, it's quite expensive if you want to return 32 GB of ram.
