Memory Configurations
The Power Macintosh 9500 Series logic board has 12 DRAM
DIMM slots, each with a 64-bit data bus. You can increase
the computer’s DRAM to a total of 1536 MB using 5-volt,
64-bit-wide, 168-pin fast-paged mode, 70 ns DIMMs.
When installing DRAM DIMMs in the Power Macintosh
9500, fill slot A6 first, followed by B6, then A5, followed
by B5, and so on. DRAM DIMMs can be installed individually;
however, to take advantage of memory interleaving, which
provides maximum performance, you must install the
DIMMs in matching pairs and in paired slots (A6 and B6
first, then A5 and B5, and so on). DIMMs purchased from
different manufacturers can be paired as long as they are the
same size and speed.
Note
: Memory interleaving allows the computer to read or
