DRAM configurations
You can increase your computer’s DRAM to up to 512 MB. The main logic board has eight DIMM slots which accept DIMMs that meet these specifications:
m8, 16, 32, or 64 MB (128 MB DIMMs are available, but they have not been tested for use with Power Macintosh computers.)
m
m
m1K, 2K, or 4K refresh rate
mextended data output (EDO) or
IMPORTANT The Single Inline Memory Modules (SIMMs) from older Macintosh computers are not compatible with your computer and should not be used.
DIMMs can be installed one at a time in any order in any of the memory slots. However, if you wish to take advantage of your computer’s memory interleaving capability, which provides maximum performance, you must install the DIMMs in pairs, and in paired slots. (Slots are paired A1 and B1, A2 and B2, and so on. It doesn’t matter which pairs you use or the order in which you use them, as long as the DIMMs are installed in paired slots.) Memory interleaving allows the computer to read or write to its memory at the same time that other memory reads or writes are occurring, thus providing approximately 5 percent to 15 percent faster performance.
To increase DRAM to the maximum of 512 MB, fill all eight slots with 64 MB DIMMs.
