Hi this is my first post ... sorry for my bad english. I can't find my answer in the forum. I hope someone can help me. I have a RDX200 and no space to put my new video card on the first PCIE slot. Is-it possible to use it in the second PCIE slot ? All I have is a black sreen. Is the second PCIE slot for crossfire only or do you have a trick to make it works ?
