i dont know any thing about your m/b but for the memory choice i would go for the fastest .... 2700......i quess it all depends what your going to do with the board....if your going to be o/cing alot ...go for the single piece of memory ...there have been problems with o/cers having timing problems with 2 or more sticks of ram in.... some people have had good experances with OCZ memory...Samsung would be better..but....if your not o/cing you can just get 2100 memory ...whatever combo you can afford..
