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
1 6 8 - p i n	1 6 8 - p i n
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.
