I'm guessing there is a "Performance" or "Expert" setting which would allow you to adjust CPU and MEM settings. I don't have that board but my DDR400 Ballistix 2x512s run CAS2.2.2.2 T1 at 400 and 433 Mhz.
Some settings used at anandtech.com w/Ballistix DDR400 in a 64 board setup.

400 and 433 Mhz timings stated 2-2-2-10 2.6V 1T
It hits as high as 594 Mhz
