sorry to resurrect this thread,

I have an E6600 with DDR2-800 RAM running on this board, my FSB wall is 341MHz, I just can't break it, even if I choose crazy voltages for both the CPU and the MB.
My RAM can't be the problem, because I even run it below the real DDR80 (400MHz)

Are there any mods, slutions to break this wall? I feel like my CPU can do a lot more than 3069 MHz.
