Model number and or Datasheet for Powermac G5 Late 2005 System Chipset

As part of a small reverse engineering project of the PowerMac G5 Late’ 05, is it at possible to find a Datasheet or reference manual on the main System Chipset / Memory Controller as found on the backside of the mainboard. In earlier models this was called the “U3” chip, I have heard that in newer models this was changed to the “U4” memory controller.

I am new to posting questions here and am sorry if this is the wrong place.

Here’s an Image of the Chipset I found Online.

Power2PC, do you have that board? Any numbers on it? Post some pictures of the board and the U2 IC with your question Aggiungere immagini ad una domanda

If it has a question mark in it, it can't be an answer.


I have now added an image I found Online of the Chipset in question.
