Alex Finkel said it first and best:
No, Sparc 5 memory does not build in pairs. You may need to put the largest
capacity SIMM in the first slot. On many Sun's, there is one simm slot "the
first" that always needs to have a simm installed in order to boot. After
that slot, you are free to use any slots but usually, if you have a mix of
simm sizes, the largest size simm needs to go into that first slot.
Thanks Alex. I also found this documented in the DSIMMs installation
instructions. Guess it helps to read the documentation carefully.
