We recently bought several IRIS 4D 20's with 8 meg of memory and then upgraded
them to 16 meg ourselves.  SGI wanted about $ 1200  a meg for memory and we
paid $ 310 a meg on the open market.  We just specified 1 meg SIMMS, 100 nsec, 
and didn't have any trouble, they are quite easy to install, and you could 
probably coerce your local SGI person to help you out.  We bought our memory
from an place called "Sophisticated Circuits" here in Seattle, their phone 
number is: (206) 547-4779.  My impression is that the price has come down 
some from this figure.
