Hey guys, I currently have the standard 6x1g and want to add 2x4gb to the remaining slots. Is there a proper way to do this? Mac Pro 2.26GHz 8-Core Xeon Nehalem How about this setup? Top Riser: 4 4 1 1 Bottom: 1 1 1 1 After reading more about the triple channeling, I'm concerned about getting the most out of the RAM. Thanks for your help!
