Hi there,
I have gone through several AMD boards looking to see if there is one that will do the job for you. Sadly I can not find your RAM on any of the QVL lists but, as I stated before, just because your RAM isn't on the QVL that doesn't mean it won't work.
The GA-MA790FX-UD5P, that you originally mentioned should be OK and the problem isn't so much with the choice of motherboard but with the CPU you decide to run with it. If you pair this RAM with an AM3 Phenom ii you will probably be able to get it to run at stated speed. One of the AM2+ CPU's might mean that you have to live with your RAM running at 800MHz.
If you decide to go with an AMD board post back with the CPU you would like to run and I might be able to give you some better advice but, from the information you have provided I think that the GA-MA790FX-UD5P will work for you.
