Has it ever been attempted to install over 16GB in a DC or QC PowerMac G5, or are we just speculating that it can't handle over 16GB of RAM? If someone has attempted to install over 16GB please post a link, regardless if it was successful or not.
Anyway Intell, what's the story behind your avatar? The mighty "Big Bird"?
It's an exercise in futility.

He has a visitor message from a muppets fan that says that it is "Narf".
Darn! Micro Center had no 4GB DDR2 sticks! I'm stuck with 12GB until I newegg the RAM.
OP,
IMHO, you can put more than 16 GB into a G5, but it does not really matter whether you slot the DIMM's or just tape them to the bottom of the case.
In any case, is your question another: "I want to see if it is possible - no matter whether it makes sense" -thing, because I really want to see you (or anyone)
a) really need 16+ GB RAM and
b) be able to convince me you would not be better off with a newer (intel) desktop mac.
RGDS,
I frequently photoshop multiple images, have 20 tabs open per window with 4 windows total, play minecraft. program in java and c simultaneously, have a web server in the background, and rarely edit video in after effects, all at once.
I currently have 6 2GB dimms installed, if I get 2 4GB dimms will the memory be shown at 20GB and have 16GB accessible or have only 12GB accessible.
He's a Muppet that I made for a high school art class. He's modeled after a real Sesame Street Muppet. For the most part, he stays in a bag in my closet. Used to take him to street fairs and such.

Wow - If you have all that open at the same time and work that way too you must be the most inneficient person on the planet.... Play Minecraft while working and at the same time edit 20 photos and code in java and c?? Lol...
My RAM has arrived, I installed it in the G5 this way
---------------4GB
---------------2GB
---------------2GB
---------------2GB
---------------2GB
---------------2GB
---------------2GB
---------------4GB
It only showed 12GB.
I tried it this way:
---------------0GB
---------------4GB
---------------2GB
---------------2GB
---------------2GB
---------------2GB
---------------4GB
---------------0GB
It didn't work, the second test ruled out bad slots, but the RAM may be bad, however I don't have another computer to test the 4GB sticks on. What should I do?
How do I check how much RAM is in the G5 in OpenFirmware?
Are you sure that your 4GB RAM sticks are low density ones? If you bought it from the bay then it's most likely that those RAM are of high density.
And are you sure that they are 533MHz?
Do they have to be low density? They are some random speed...
In order for it to work 100% guaranteed, it should be PC2-4200 533Mhz low density. That's DDR2.
