The answer would be that you can use /60 memory in a /90. HOWEVER, you have
to add memory to the /90 in sets of 4, while the /60 only requires sets of
2. The other problem is the memory has to go in a special order, you'll
need to look really closely at the Motherboard in order to see how they go
(it's not easy to see the markings).

BTW, it's cheaper to buy a /60 to get RAM than to go out and get RAM.
