Memory dividers are "ratios" for CPURAM frequencies. For example, if your FSB is running at stock 133MHz, your dividers would yield the following:
4:3 -> 133 x (4/3) = 100 (x2 for DDR) = 200 MHz RAM Speed
1:1 -> 133 x (1/1) = 133 (x2 for DDR) = 266 MHz RAM Speed
3:4 -> 133 x (3/4) = 177 (x3 for DDR) = 345 MHz RAM Speed

DEWD!!!!!
They are called memory dividers because you DIVIDE by them
in your example 133 x (4/3) = 177 (x2 for DDR) == 354mhz ram speed
but in realy its 133 / (4/3) == 100 (x2 for DDR) == 200mhz RAM speed
So if you want to achieve DDR400, you need to run your FSB at 150mhz and set your memory divider to 3/4 ===>
150 / (3/4) == 200 (x2 for DDR) == 400mhz RAM
