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.

*The PCI slots can accommodate mixed-voltage (5.0 V, 12 V, or 3.3 V) cards but only at

3.3V 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 PCI slots. Damage to 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 illustrations in the following procedure show how to replace an AGP video card. 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.

Tools Required

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