I am no quad rank dimm expert, but I think few boards support them. One is Serengeti Cheetah. I remember asking why one processor socket has 4 dimm slots and another 8. I was told it was for quad rank dimm testing. The chip selects for two normal dimm sockets are combined and routed to a quad rank socket, if I remember correctly. I don't even have any quad ranked dimms to test with. I think they are rare.
Actually, they are not *that* rare, since they are readily available:
