killagbear - What is the exact name of your motherboard? Is it just plain "EVGA 790i Ultra SLI" or is the name longer? Is there something that comes after the "Ultra SLI" in the name? Any chance you can identify the part number? The reason I ask is there were several variations of the board and some of the SATA configurations were different. Better still would be the EVGA part number.
japps2 - GEEZ! That was a very long thread you linked to. It took me a while to read all of it and digest it. It's also a very old thread from last May about trying to install an Intel ssd. Killagbear may only need to update the BIOS to install a Crucial ssd. Users have reported installing Crucial and OCZ ssd's without too much fuss.
