I have searched, but could not find an answer to the following. I have a brand-new 8-core Mac Pro. The Apple store installed 4 x 2GB DDR3 RAM and I would like to add another 4 x 2GB. It probably doesn't matter which manufacturer I choose if the spec is the same, however, to minimize the chance of any problems I thought I would go with an OEM. I heard that OCZ is one of two OEMs for Apple (the other being Samsung?). RAM Memory Upgrade: Dell, Mac, Apple, HP, Compaq. USB drives, flash cards, SSD at Crucial.com gave me some basic recommendations (their scanning tool didn’t work last night), but it doesn't state the manufacturer. OCZ Technology | Welcome! lists 10 different types of DDR3 RAM (Flex XLC series, Reaper series, Platinum series, etc.) Can anyone please enlighten me which of these series will work with the Mac Pro and what the pros and.cons are if there are multiple choices. Thank you.
