I have installed EVGA and Gigabyte cards on these motherboards and from what I can tell the mobo doesnt like this card specifically. I have 14 Gene motherboards here and I haven't seen one that can recognize any of the 7x 750 Ti's I have (
http://www.newegg.com/Product/Product.aspx?Item=N82E16814125502). The boards are happy with the GTX 770 2GB windforce's, EVGA GTX 780's and even a few 650s I have installed. Latest Nvidia drivers say they cannot detect a compatible GPU with the 750Ti installed. BIOS is obviously updated (these boards hardly boot at all with original BIOS). I've been extrememly happy with the hardware I have from ROG but I wish these cards would work as I bought several of them assuming they would work with the rigs I need them for.
