anyone tested it? (this one with 2 CPU sockets, single U320 SCSI single
100Mbit ethernet and single 1000Mbit ethernet)

is ahc comment in manual:
     Double Transition clocking is not yet supported for Ultra160 controllers.
     This limits these controllers to 40MHz or 80MB/s.

still true?

so this 320MB/s will be really 80MB/s?
