Would like to install a Quicksilver 933MHz processor in a Digital Audio. I know there is a missing mount point on the DA motherboard that would correspond to the to the 4th mounting point on the QS processor. I guess my question is: where can I find the information detailing how to go about the best way to do any wiring, etc. needed to make this upgrade work. Appreciate any help. Thanks

Yes, this can be done. There is another thing that you need to do. 12v needs to feed to one of the CPU module's legs. There are details here: http://homepage.mac.com/josephk/G4_mod.html
Ignore the stuff about changing FSB settings, it is for putting the quicksilver module in a Gigabit Ethernet.

The other thing that you want to be careful of is cooling. Use the original 933 Heat sink, not the one from the Digital Audio. You might need an extra fan as well. There's more info out there. I just can't find it at the moment. xlr8yourmac.com is good for this level of modding.

Thank you very much for your response. I took a look at the page you directed me to and found some very useful information. I placed my QS processor onto a DA motherboard and ran 12v to the 4th terminal and fired it up and it runs great. All of this is inside a QS case but will be moving to an ATX case soon that will give more room and let me add even more fans. Right now I have installed an extra fan in the place where the speaker goes in the QS case, blowing into the case for some extra cooling and it seems to be doing the trick, never above about 98 degrees fahrenheit. Once again, thanks.
