I have a EVGA 780i SLI motherboard. I currently have according to Everest DDR2-667 ram in my system, which is PC2-5400, I know my ram is running at 1066MHz, my mobo according to everest says it supports up to DDR2-800 which is PC2-6400, I believe PC2-6400 is what I actually have in my system, I am getting PC2-8500 ram at 1066Mhz, will I be able to run it? I have seen many articles about other issues, but they mention they are running pc28500 ram (8gb at that) on the 780i motherboard. I dont know how to confirm or not confirm this, so I am asking here. And if I can run it (i hope) why would a motherboard state less then what it does. And here http://www.evga.com/products/moreInfo.asp?pn=132-CK-NF78-A1 Says up to 1200MHz ram, I am getting confused.
