SDRAM DIMMs
The Power Mac G4 uses the following types of SDRAM DIMMs:
PCI/AGP/Gigabit Ethernet
QuickSilvers/
Digital Audio
PC-100 SDRAM PC-133 SDRAM
3.3 volt unbuffered 3.3 volt unbuffered
168-pin 168-pin
64-bit wide 64-bit wide
PC-100 DIMMs from recent Power Macintosh G3 computers are
compatible with Power Mac G4 (PCI Graphics/AGP Graphics/
Gigabit Ethernet) computers; DIMMs in older Macintosh
computers are not. Do not use older DIMMs even if they fit into the
Power Mac G4 DIMM slots. Power Mac G4 (Digital Audio)
computers must use PC-133 DIMMs, not PC-100 DIMMs.
