Installing Memory

Depending upon the model, your Power Mac G5 has four or eight dual inline memory module (DIMM) slots for Double-Data-Rate (DDR) synchronous dynamic random-access memory (SDRAM) devices. Your computer comes with a minimum of 256 MB of random access memory (RAM), installed as a pair of 128 MB DIMMs in two of the DIMM slots. You can install additional pairs of DIMMs in the open DIMM slots on your computer's main logic board.

For more information on the memory and memory specifications, see Power Mac G5: Memory Specifications and Requirements. To purchase memory for your Power Mac G5, see an Apple Authorized Service Provider or Apple retail store or purchase it online at the Apple Store.

Installing Internal Storage Devices

Your Macintosh has three internal drive bays: one optical drive bay and two hard drive bays. In most configurations, a single hard disk drive occupies the top hard drive bay and an optical drive is located in the front optical drive bay.

Your computer comes with an optical drive installed, either a SuperDrive or Combo drive. You can replace this drive if you wish.

You can add a Serial ATA disk drive to the empty slot in the hard disk drive bay. The drives must meet these specifications:

  • Type: Serial ATA
  • Width: 3.9 inches (102 mm)
  • Depth: 5.7 inches (147 mm)
  • Height: 1.0 inch

Important: Use the original Apple cables that came with your Macintosh when you install ATA or optical drives.

To purchase an additional hard drive or a replacement optical drive for your Power Mac G5, see an Apple Authorized Service Provider or Apple retail store.

Installing a PCI Expansion Card or Replacing the AGP Card

You can expand the capabilities of your Power Mac G5 by installing cards in its expansion slots. Your Power Mac G5 has four expansion card slots, three of which accommodate Peripheral Component Interconnect (PCI) cards and one that accepts an advanced graphics port (AGP) card.

AGP cards and PCI cards have different connectors, so you cannot insert a PCI card into the AGP slot.

About AGP Cards

Your AGP card, installed in slot 1, contains the graphics processor unit (GPU) and provides the computer's display ports. Slot 1 is designed specifically to accept AGP cards. This 533-megahertz (MHz) slot accommodates 1.5-volt (V) AGP cards.

You can replace the card that came with the computer with an AGP 8X or AGP 8X Pro card. A replacement AGP card must have driver software compatible with Mac OS X.

About PCI Expansion Cards

Your Macintosh has three expansion slots, labeled 2, 3, and 4, which can accommodate expansion cards up to 12 inches long. Depending upon the model of your Power Mac G5, you can install either PCI or PCI-X cards.

Maximum power consumption for all four expansion slots (the three PCI expansion cards and the AGP card) should not exceed 90 watts (W).

PCI slots 2, 3, and 4 64-bit, 33 MHz
PCI-X slots 2 and 3 64-bit, 100 MHz
slot 4 64-bit, 133 MHz
The PCI slots can accomodate mixed-voltage (5.0 V, 12 V, or 3.3 V) cards, but only at 3.3 V signaling, with 32-bit or 64-bit data widths and a 33 MHz frequency. You can add a 66 MHz card to a 33 MHz PCI slot if the card can operate at the lower 33 MHz rate.

Warning: Do not use PCI cards that function only at 66 MHz in the 33 MHz PCI slots. Damage to your equipment could result. If you have a 66 MHz PCI card, check with the card's manufacturer to see if it also works at 33 MHz.

To determine whether your computer has PCI or PCI-X slots, read the ID label, which is located on the side of the computer at the bottom under the air deflector. Your computer's ID label tells you what hardware configuration you have. If your computer has PCI-X slots it will be listed here. If you don't see "PCI-X" your computer has PCI slots.

You can also identify your model by the number of DIMM slots. Computers with 4 DIMM slots have 33 MHz PCI slots; computers with 8 DIMM slots have 100 and 133 MHz PCI-X slots.

Installing an AirPort Extreme Card

AirPort offers an affordable and easy way to provide wireless Internet access anywhere in the home, at work, or in the classroom. You can install an AirPort Extreme Card in your Power Mac G5.

Important: You must install an AirPort Extreme Card. Older AirPort Cards will not work in the Power Mac G5.

For more information on the AirPort Extreme antenna, see Power Mac G5: External Antenna Required for AirPort or Bluetooth Reception. To purchase an AirPort Base Station or AirPort Extreme card for your Power Mac G5, see an Apple Authorized Service Provider or Apple retail store or purchase it online at the Apple Store.

Replacing the Battery

Your computer has a 3.6 V lithium battery on the main logic board. If your computer has intermittent problems starting up or random changes in its date and time settings, you may need to replace the battery. Purchase a replacement battery from an Apple Authorized Reseller.

Important: Batteries contain chemicals, some of which may be harmful to the environment. Please dispose of used batteries according to your local environmental laws and guidelines.
