I have an awesome Maximus VI Hero with a 4770k and 16GB of RAM and I have the opportunity to add 3 750ti for folding purposes (understanding they cannot be in sly, but that they do not need a 6 or 8 pin connector. The two currently give me about 155k PPD and I am being offered another one that I can use.
What I am curious of is what is the status of what I have read around different places that the 3 1x slots are disabled. I have a SATA card that is in 1 of the 1x slots and it has 2 drives connected to it, so I want to still use it.
I have read it disables them if the 3rd slot is not run at over 1x. Is this true? So, say if I run the 3rd GPU at 4x (as I believe it is supported by the board) then should the 3 1x slots still be enabled?
