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.

Thanks,
Scott
