Power Mac G5 (Late 2004) Basics - 5
What’s New
DDR Memory
In the Power Mac G5 (Late 2004) computer, PC3200/400 DDR-SDRAM DIMMs must be
installed in pairs of equal size and speed. Memory from older Macintosh computers is not
compatible. Do not try to install non-DDR memory as it will not fit in the DIMM slots and
could cause damage.
The computers ship with a minimum of 256 MB of RAM, provided by a pair of 128 MB
DIMMs installed in the two DIMM slots marked “1.” You can add DIMMs, provided they are
installed as a pair of equal size, in the two DIMM slots marked “2.” A diagram on the logic
board near the DIMM slots illustrates how the pairs must be installed.
Graphics Cards
The standard Power Mac G5 (Late 2004) computer comes with an Nvidia GeForce FX
5200 Ultra graphics card installed. The supported graphics cards are shown below:
The CTO ATI Radeon 9800 XT, Nvidia GeForce 6800 GT DDL, and Nvidia GeForce 6800
Ultra DDL cards occupy both the AGP slot and the adjacent PCI slot. For this reason, the
number of available PCI slots is reduced from three to two.
