Does anyone have any expierience using 3 way sli with something like a 580 or 570? I just want to know whta My options are as im looking into getting a new graphics card setup.
The black part simply means the motherboard supports 3-way SLI, without mentioning the speed of each slot.
The orange part is inaccurate. Your memory must have failed you. This motherboard can run x16/x8/x8 or x16/x16/x1 but not x16/x16/x8.
Take a look at the 2 pages of the User Manual below:-
page xi :- shows the 2 possible combinations
page 2-21:- detail explanation of each possible combination
Finally, for 3-way SLI, you will definitely want x16/x8/x8
whose speed is only a few % behind x16/x16/x16. The other option ( x16/x16/x1 ) will just be a total failure as the x1 speed slows down the entire setup too much. Take a look the 2 charts below. Note that when you get down to x4, the performance decrease is noticeable. x16 and x8 gives quite healthy performance.Edited by windfire - 7/17/11 at 2:26am
