That would make sense given that it looks like only 7.5Mb is showing up as being available (or doesn't it work that way?).

However, I've had a look at the jumper settings and only the RAMSPEED wires have a jumper sleeve over them (techno-speak ). I'm determining which jumper is which by reference to the Blizzard manual.

That seems to contradict your theory unless for the Blizzard the jumper setting are removed by slipping the jumper sleeve over the wires! Seems unlikely to me but I can send a pic of the jumper settings if need be.
