Re: Swapping out a G5 Motherboard

Re: Swapping out a G5 Motherboard
Hi Andreas, Thank you for the information and response. Very helpful. Where can I obtain such a disc? Most sites that tout a free download isn't such at all (membership fee with no guarantee that I'll get what I need), or outright bogus. Any concrete directions would be greatly appreciated.

Simply, can one swap good G5 CPUs into a replacement motherboard without any problems? Thanks, Dana On Oct 2, 10:56 pm, DLC dlcatft...@gmail.com wrote: Greetings all.

Regards, Dana From what I’ve heard, you will require a Apple Service Diagnostics disc from which you have to boot and to recalibrate the CPUs with the mainboard. If you don’t, you might get very loud fans in the good scenario or burn anything on the mainboard or the CPUs in the bad scenario. But this is just what I heard, not what I know. The thing with the service code to activate them is also something that sounds reasonable to me… For G5s, you need the 2.5.7 ASD discs. For the Late-2005 G5s, the last G5s built, you will require the 2.5.8 ASD discs. You may be able to find a downloadable version, but be aware that Apple never officially made a download available for this. Since Apple abandoned the Power Macs in my sense you can consider it to be Abandonware though. The swap will work if the CPU is the same series. For instance, you will have to use a PowerPC 970 processor for the original G5, a PowerPC 970fx will not work. And I’m pretty sure that for the later models using the PowerPC 970fx processors, a PowerPC 970 will not work. The same goes for the PowerPC 970MP which can only be found in the Late-2005 G5s. The June-2004 has PowerPC 970fx processors. Good luck!

Can’t adjust brightness on ADC monitor
I have two monitors on a PowerMac G4 (dual 500MHz): one is a Viewsonic on DVI, the other an Apple Studio 17 on ADC. Is it normal that I can’t adjust the brightness on the Apple monitor now? There’s no slider for it in the screen’s preferences, and pressing the button on the screen frame doesn’t bring up the usual dialog. Maybe I should mention that both monitors are connected to the same graphics card, a GeForce4 MX (AGP). If this is indeed the common behaviour, my theory is that the OS (10.4.11) can’t get a handle on the Viewsonic’s brightness, and then disables the software control for both. But I think it’s strange, given that other settings can be adjusted for each screen separately. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Is it normal that I can’t adjust the brightness on the Apple monitor now? Now implies something has changed...what is it? Do you get the expected behavior back when whatever that is is undone? You should be able to do everything separately on the two monitors. Did you try trashing the display prefs?

PowerMac G5 Won't Power Up, Light Stays On
Hi all, hoping I can get some help with this problem. I received two identical 1.6GHZ G5 Towers. I plugged them both in, and as soon as I plugged in the monitor, the computer powered up and booted into OSX. I shut it down, but instead of shutting down, it just restarts. I tried plugging the monitor and keyboard in, then the power cord. It didn't power up, but the power light stays on, and the computer won't power up when you press the power button. I tried zapping the PRAM, which didn't help. These two computers have the exact same problem, so any help would be greatly appreciated.

When I plugged in a monitor to the DVI connection it worked. Apple shipped a lower wattage unit with the 23; this professor went through two of them under warrantee, until he got Apple to swap it out for a power brick from a 30...no problems since. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
