Replacement Instructions

Follow the instructions in this sheet carefully. Failure to follow these instructions could
damage your equipment and void its warranty.

Online instructions are available at http://www.info.apple.com/installparts/.

Note:

These instructions apply to different versions of the Power Mac G5. While some
models may look slightly different from the one shown in the illustrations, the steps for all
models are the same.

AGP and PCI Cards

The Power Mac G5 computer has four expansion card slots, three of which accommodate
Peripheral Component Interconnect (PCI) cards and one that accepts an advanced
graphics port (AGP) video card
connectors, so you cannot insert a PCI card into the AGP slot.

Note:

Maximum power consumption for all four expansion slots (the three PCI expansion

cards and the AGP card) should not exceed 90 watts (W).

AGP Cards

The AGP video 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.

PCI Cards

The remaining three expansion slots, labeled 2, 3, and 4, accommodate PCI cards up to
12 inches long. Depending on the Power Mac G5 model, you can install either PCI or
PCI-X cards.

Note:

To determine if your Power Mac G5 computer can accommodate PCI-X cards,
check the number of DIMM slots on the logic board. Computers with four DIMM slots have
33 MHz PCI slots and cannot use PCI-X cards; computers with eight DIMM slots can
accommodate 100 and 133 MHz PCI-X cards. See the chart below.

Card type PCI slot Card speed

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 accommodate 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:

the equipment could result. If you are installing an additional 66 MHz PCI card, rather than
replacing an existing PCI card like-for-like, check with the card’s manufacturer to see if the
new 66 MHz card also works at 33 MHz.

Note:

The replacement procedure for a PCI card is similar. However, remember that only AGP
cards can be installed in slot 1; PCI or PCI-X cards must be installed in slots 2, 3, or 4, as
described in the chart above.

Do not use PCI cards that function only at 66 MHz in the PCI slots. Damage to

The illustrations in the following procedure show how to replace an AGP video card.

Tools Required

The only tool required for this procedure is a Phillips screwdriver.

Opening the Computer

1. Shut down the computer.

Warning:

internal components or the components you are installing. Do not open the computer
or attempt to install items inside it while it is on.

2. Wait 5 to 10 minutes to allow the computer’s internal components to cool.

Warning:

You must let the computer cool down before continuing.

3. Unplug all external cables from the computer except the power cord.

4. Touch the metal PCI access covers on the back of the computer to discharge any

static electricity from your body.

Important:

components inside the computer. To avoid generating static electricity, do not walk
around the room until you have finished working and closed the computer.
