part1: I have a motherboard with nforce4 chipset. It has two pci-express slots that are x16 and one x1 and 1 x4. I know that the two x16 can be used for sli graphics but can they be used for anything else? I am using the first x16 for a graphic card at the moment but i would like to use the second x16 for a disk controller. Is that possible?
part2: if the answer to the above is yes, can the controller be an x8 card? i believe that it will physically sit in the slot but i do not know if it will work.
if you need any more specific details please ask. thanks
