Important: Whenever you replace a processor with a new processor, you must run Apple Service Diagnostic (once the computer is reassembled). You must also run the diagnostic if you re-install the same processor but in a different connector from the one in which it was originally installed. Apple Service Diagnostic for Power Mac G5 is available as a download from the Disc Images section of the Apple Service Source website. For more information, see Thermal Calibration in the Troubleshooting chapter.
Hey- If you want an original nVidia GeForce 5200 Ultra, I've got one. This originally came with a 1.6 Ghz G5... if you are interested, PM me.v-i-c- said:ok - i got most of the parts that i need for my frankenstein G5 (1.6/1.8) - just need the screws and the graphicscard now - for the first attempt to bring the G5 to live i want to use an old graphicscard: the ati rage 128 (agp) from an old G4
any idea if i run in trouble using this card? i heared that older agp-cards needs different voltages and that they can damage modern mainboards - is that true? has anyone ever tried to put such an old card into a G5?
If you flash the 9800 pc, will it work in a MDD PowerMac G4? Do you have detailed instructions on how to do this?Hector said:yeah dont do it older cards run at much higher voltages, if your cheap get a 5200 off ebay if your adventurous buy a pc 9800 and flash it (it's not to hard if you have a pc and there are no resistor moves or anything like that) if your rich get a 9800se mac edition for $$$$.
You might want to ask Hector why the calibration program on the Apple service disk (for Service Techs) didn't work.v-i-c- said:don't try it! - calibration will not work because processor is to fast - need help - any oher way to "calibrate" fans?

The windtunnel (mirror-drive doors) was the noisest. I don't see how you can say the cube is loud considering, it has no fans at all.v-i-c- said:just found this on the web
"the G5 is second only to the Power
Macintosh G4 Cube in terms of noise when everything is working
properly. Similarly, the G5 is second only to an F-16 on afterburner
when the system has sensed an error.
If there is a temperature-sensing
problem in the G5, the system employs a fail-safe feature to ensure you
don't burn up the computer. As some of you may know, the fail-safe
procedure is to turn ALL the fans on and set the fan speed to
"deafening" while slowing the processors down to 1.3GHz."
run some tests - looks really like working in energy save mode all the time! maybe i have to "flash" the board?? to prevent that fail save feature?
WOWv-i-c- said:ok it took me a little bit to get all parts but finally it works - YOU CAN UPGRADE YOUR G5 1.6 to 1.8GHz with a new processor - systembus will raise to 900mhz too!
i did it this night
Building an 1.8GHz PowerMac G5 using an 1.6GHz Mainboard
that's the point here - if we get rid of the problems the answer is: yesHow about if you have bought a SP PM can you later add another cpu to the board
ok maybe i should explain it again:edit: but it does not seem to work that well. or is it just the fan noise
i didn't said that - Duane Letourneau said it in "G5 Thermal Management"The windtunnel (mirror-drive doors) was the noisest. I don't see how you can say the cube is loud considering, it has no fans at all.
oh! i understand now. Thanks for clarifying. I had a Single 1.8 and when that thing went to full speed - It sounded insane.v-i-c- said:i didn't said that - Duane Letourneau said it in "G5 Thermal Management"
he wanted to say that the G5 is really a quiet Mac and that there is only the cube which is more quiet (and some iMacs and iBooks ) - the G5 is not louder than the G4 MDD normally but when this "safety mode" is activeted and the fans are running really at it's full speed then it's louder than everything i ever heared - (i have the dual 2.5GHz whith GeForce6800 ultra DDL which is the loudest G5 - the liquid cooling system doesn't reduce noise because there are still all that fans in the machine and the gf6800 is loud too - the dual 2.5 is nothing compared to the other G5 in it's safety mode, i would say it's feels 10 times louder than the 2.5 at it's highest sound level)
he's saying the only mac quieter than the G5 is the cube.jackieonasses said:The windtunnel (mirror-drive doors) was the noisest. I don't see how you can say the cube is loud considering, it has no fans at all.
