I am not sure if the motherboard is still supported by ASUS. The last BIOS update was released in 2010. I want to make 100% sure that this card would work fine with the m/b. Can somebody help me.. Thanks Raj More about : pcie compatibility pcie calinkula March 28, 2012 11:27:10 PM A pcie 2.1 card in a 1.x slot is a bit unreliable. It would be much better to use a 2.0 card.
