Well your motherboard only supports 400Mhz RAM "This motherboard supports any Socket 939 AMD Athlon64/FX processor on the market and can be stuffed with up to 4GB of unbuffered non-ECC PC3200 DDR RAM", so I don't believe you.... but anyway if I upgrade my PSU to a decent size what would u guys rate my PC? Also, what are some good branded PSUs?
