General/SDRAM Do’s and Don’ts - 20

 

recent efforts to qualify PC100 SDRAM for earlier versions of G3.

Zero MB of memory is soldered to the Power Macintosh G3/

Macintosh Server G3 (Blue and White) main logic board. If all 

four of the DIMM slots are empty, the machine will not operate. A 

single-frequency tone will be generated indicating that no 

memory is installed.

The DRAM DIMMs can be installed one or more at a time. There are 

no performance gains when two DIMMs of the same size are 

installed. Any supported size DIMM can be installed in any DIMM 

slot, and the combined memory of all of the DIMMs installed will 

be configured as a contiguous array of memory.
