I can reduce the memory bus speed to 333 (which would equal a 4:5 ratio) or even 266 (which is 1:1), but that seems like a waste of money on the RAM front, because my 4 sticks would all effectively become PC-4200 rather than PC-6400...., but would a 1:1 ratio be "better" somehow than 2:3?
I am not trying to overclock anything at all, I just don't really get the whole "timings" thing....
Many thanks
