Neither of those boards have any support for that Xeon CPU.
You're going to need to find a motherboard that supports it, the only one I know of offhand is the Asus P6T WS series of boards. There's probably a couple more, Asrock I know likes to put Xeon support in some of their boards (they're also a subsidiary of Asus).
I checked the asrock website. It shows support for my processor. Do you have this board and if so what is your opinion?
Thanks for your input.
