BD7-11 Ram/divider ?

I have been thinking of building a p4 ddr rig and had pretty much decided that it would be a Sis654dx based system because of the memory dividers available. But recently I noticed that a lot of Oc'ers were using the Bd7-11 mobo. I have read that it can run a 3/4 divider above 133 mhz. Is this true an or is it only with one of Mr Naturals hacked bios's. Please give me the skinny on this mobo, pros and cons. Any other suggestions the main interest in the bd7-11 is that it can lock the pci at 33 or 37mhz I believe. But I also want the best possible memory settings/bandwith.
