I have tested 4Mbit simms on a 4D/25 without problems.  I took it
all the way to 64Megabytes.  However, you need to be at a certain
rom revision in order for the 4mbit simms to be recognized.  
I believe the revision is 3.2 rev E (I would really appreciate
someone at SGI confirming this).  

Please note the following: 
You cannot mix 1 megabyte simms and 4megabyte simms together.
It is all or nothing.  You must also add in increments of 4 simms 
(16 Megabytes).

My vendor is Impediment, 617/837-8877.  I don't have a price since
I got these simms on loan for evaluation.
