dividers aren't dictated by memory at all. I see what hot_fifty is trying to say. Maybe at a low enough fsb, the board will switch to another strap, which has a different set of dividers.

That said, I know for a fact p35 has 1:1 in at least 266strap (of course 333 too). However, I can't say the same for g33 at the moment, although I wouldn't be surprised if it's just something gigabyte is working on
