Power Mac G4 Cube: Must Use 35 mm RAM DIMMs

This document provides information about physical RAM DIMM specifications that apply to the Power Mac G4 Cube computers.


The height of memory cards (RAM DIMMs) used in Power Mac G4 Cube computers must not exceed 35 mm. While the RAM DIMMs from a Power Mac G4 Cube computer may fit and function normally in some Power Mac G4 desktop models (Note 1), the reverse is not necessarily true.

The complete specifications for the Power Mac G4 Cube RAM DIMMs are:

• PC-100 SDRAM
  • 3.3 V
  • Unbuffered
  • 64-bit-wide
  • 168-pin
  • Running at 100 MHz
• Maximum height 35 mm

Compatible capacities:

• 32 MB, 64 MB, or 128 MB DIMMs (64-bit-wide, 64 Mbit technology)
• 128 MB or 256 MB DIMMs (64-bit-wide, 128 Mbit technology)
• 512 MB DIMMs (64-bit-wide, 256 Mbit technology)

Notes

1. Includes Power Mac G4 models with 100 MHz system bus (PCI Graphics, AGP Graphics, and Gigabit Ethernet). Does not include Power Mac G4 models with 133 MHz system bus (Digital Audio, QuickSilver, QuickSilver 2002).
