Everyone seemed to be in agreement that the largest simm should go in the 0
slot. Where the rest went -- most people said didn't really matter, some said
that to be sure I should use slot 0, 1, 2. That's what I did, put the 3rd
party 64 simm in slot 0 & the two 32 simms in slots 1 & 2. So far so good!
Some people had bad experiences with 3rd party memory & others didn't. A
couple of people sent me nifty diagrams (since it's hard to tell exactly with
slot is which -- no clear lables on the motherboard!)
I'm gonna include those replies below. Thanks again for all your help.
