Added memory to Ultra60

I added 12 DIMMS (said to be compatable with Ultra60's dual processor) to
increase to 2GB.   When I reboot, the memory stays at 512MB of RAM (that
is what it was before).  I run a check of the slots and it shows that
there is nothing in there. (see below).  

My question is, do I need to do something in the firmware to make it
recognize the new slots?  Is there a jumper setting?  I tried /reconfigure
but that didn't seem to make a difference.  I only see 512MB displayed on
the OpenBoot screen.   Is it possible the DIMMS are not seated all the
way?  Any ideas would be helpful - thanks.
