Where do you find these 69 pin fb-dimms. It looks like everything I can find on newegg is 240 pin fb-dimms?

FB-DIMM pins

Actually only the interface at the memory controller is 69 pins (allowing more channels from one memory controller chip). The FB-DIMM needs these 69 pins, plus 69 pins to talk to the next FB-DIMM, plus additional pins for power and ground; that's why they have the familiar 240-pin form factor.
