I recently bought a 2010 Mac Pro on eBay it's the 2.8ghz quad core Xeon version. It has 2, 8GB ram modules installed (I'm assuming stock) in 2 of the available 4 slots. I'd like to get 2 more 8GB modules for a total of 32GB. I know apple has some weird requirements for their RAM so I figured I would just ask here before I buy something random on newegg. What has worked best for you guys? Here is a picture of the stock ram that is in it now. Front and back.
