Just a note, the 166-200MHz signaling is usually used for mainboards
that have an L3 cache ala Alpha mainboards.  There is also a
"Slot-B" interface that some Alphas use that feature a 128-bit wide
bus at 100MHz DDR.  That's 3.2GBps per channel!  Mix in 4 CPUs (each
talking at 3.2GBps), 2 memory busses (each talking at 3.2GBps) and 2
PCI-64bx66MHz busses (each talking at 0.5GBps) and you've got
yourself serious I/O potential.
