Hey guys! I just recently purchased a mac pro for my home studio and have been looking to upgrade my RAM. I am currently just looking for a 4gb update, preferably a 2x2gb setup. I ran into this RAM on Ebay called OPTIVAL by Omni Technologies for about $319. Now, I have done my research with RAM for the MAC PRO so I know my way around. Any one here have experience with this RAM? If so, thoughts? Any help would be GREAT!
