I am having trouble finding the perfect RAM to use to upgrade my 8GB. I have a 2010 Mac Pro 5.1 single 6-core with only 8GB of ram. 1) What is the maximum amount of ram the single processor can have? 32GB? 2) What is the best (I do not care about expense) ram to use for the upgrade to the max? I looked at Newegg and OWC. I just am not sure what to get and some of the ram on Newegg has bad ratings.
