Specifics regarding the memory for each Power Macintosh G4 model is provided on the specs page for every system, but general information regarding the type of memory, number of memory slots, and maximum supported RAM when running MacOS X also are provided below.
MacOS 9 supports a maximum of 1.5 GB of memory -- and a maximum of 1 GB allocated to a single application -- so systems that can support 2.0 GB booting MacOS X still are limited to 1.5 GB booting MacOS 9.
Please note that just because RAM meets the minimum listed criteria does not mean that it will necessarily function as intended in a particular Mac. When buying memory, be sure to buy from a quality vendor that has tested their RAM with your Mac to ensure compatibility.
Direct links to Apple instruction manuals (PDF) with official memory installation instructions and instructional videos and compatible memory for sale from site sponsor Other World Computing have been integrated into the below chart for your convenience.
Try Mactracker, a Macintosh application (free to download and use) that has information about Apple products back to the Apple I from April 1976, including iPods, iPhones, iPads, desktops, and software. You'd use this to look up information, including memory specifications, for any Macintosh ever made. The desktop version runs on pretty much anything from OS 8.5 to current releases of OS X. Mactracker is also available for iOS.
In your case, Mactracker lists 20 models of Power Mac G3/G4/G5 computers. The information includes an overview, software, memory and graphics, connections (Ethernet, USB, Firewire, audio, etc.), history and links to Apple manuals.

Adding more memory, or RAM, is the least expensive and easiest way to upgrade your Mac. It lets you run more applications and keep more files open simultaneously. Most Macs have more than one slot to install RAM into, but certain laptops and early iMacs have limited slots, so in those cases it helps to purchase the largest memory sticks you can.
If your computer doesn't boot and the problem is the RAM/memory, you won't be able to hear a startup sound, and the power-on light will flash in a sequence of two, three, or four times. The number of times that the light flashes tells you what particular problem with memory you have.
If you already installed memory, then the problem might be with it not being secured into its slot. In this case you should make sure that it is securely placed into the slots specified for RAM. If no memory is installed, then you should install them into their respective slots. If all goes well it should boot up again, but if the light still continues to flash, we suggest you contact Apple Support for assistance.
If three flashes occur, that means that the memory that you installed is not supported by the computer system. You should only install memory that is supported by logic board. We recommend that you remove the current memory and install ones that are supported.
Either the memory or the memory slots may need to be replaced with new ones. You are going to have to check the pins on the logic board in order to decide if it needs replacing. You don't need to completely remove the memory slots, you just want to be able to see if there are any bent pins. If there are bent pins, you will have to contact Apple for replacement parts and repair services. But if you don't find any bent pins, all you need to do is reset the logic board. This can be done by removing the video card from the logic board and pushing the reset button (S1) on the board.
If nothing that you've done to try and fix the problem works, then there is usually only one main solution, which is to replace the logic board entirely. Since the logic board contains multiple components that don't all rely on each other, they can all malfunction separately and not affect the functionality of other components. If you have tried replacing a broken component like the graphics card, memory or display and the original problem is still present, it is highly possible that the logic board needs to be replaced.
If I try to boot using Linux debug at the yaboot prompt, it probes the ide devices (not the partition tables), starts up the TCP stack, and the last few messags are:[ 28.852783] Freeing unused kernel memory: 180k init[ 29.013427] Capability LSM initialized[ 29.121935] Found KeyWest i2c on "uni-n", 2 channels, stepping: 4 bits[ 29.128864] Found KeyWest i2c on "mac-io", 1 channel, stepping: 4 bitsThen it hangs for a little while and drops into BusyBox.
