- The Quadra 950 does _not_ require that larger capacity DRAM SIMMs be
- placed in the lower (or upper, for that matter) SIMM bank. You can place
- either 4MB or 1MB SIMMs in any bank, in any order. At startup memory is
- sized independently for each bank, and then all banks are stitched
- together in hardware into a single contiguous physical address space.
-
- Whatever your problem was, it was not solved by placing the larger SIMMs
- in the lower bank, per se. Perhaps one of the SIMMs was not seated
- properly in the socket in your original installation?
