Important: Always discharge static before you touch any parts or install any components inside the computer. To avoid generating static electricity, do not walk around the room until you have finished installing the expansion card, memory, or internal storage device and closed the computer. Warning: Always shut down your Power Mac G5 before opening it to avoid damaging its internal components or the components you want to install. Do not open the computer or attempt to install items inside it while it is on. Warning: After shutting down your computer, the internal components can be very hot. Let the computer cool down before continuing. Touch the metal portion of the PCI port access covers.

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. DIMMs must be installed in equal-sized pairs and fit these specifications: • 400 MHz, PC 3200 DIMMs • 2.5 volt (V) • 184-pin module • Maximum number of memory devices on DDR SDRAM: 16 • Nonparity • No error-correcting codes (NECC) • Unbuffered (registered or buffered DDR SDRAM cannot be used) Important: Memory from older Macintosh computers may not be compatible with your Power Mac G5. Note: When purchasing DDR SDRAM for use in Macintosh computers, make sure that the memory vendor conforms to the JEDEC (Joint Electron Device Engineering Council) specification. Check with your memory vendor to ensure that the DDR SDRAM supports the correct timing modes and that the Serial Presence Detect (SPD) feature has been programmed properly, as described in the JEDEC specification. To check the compatibility of your DDR SDRAM DIMMs, see the Macintosh Products Guide on Apple’s website at You can purchase Apple-branded memory online from the Apple Store at store.apple.com.

Important: Always install DIMMs in pairs of equal size and in the order designated in the illustration above. No matter how many SDRAM slots your computer has, the SDRAM DIMMs must be installed in pairs with one DIMM per bank. DIMMs are already installed in these two slots. Install additional DIMMs in these two slots first. If slots are available, and you want to install more memory, install additional DIMMs in a similar fashion: In pairs, one per bank, from the center outward. Bank 1 Bank 2 3 Open the ejectors on the DIMM slots by pushing them out to the sides. 4 Placing one hand on the back of the computer for support, align the first DIMM in the slot and push both ends of the DIMM down until the tabs are vertical and the ejectors snap i...
