Q: Chud tools for Powermac G5

Quad 2.5 Powermac G5

OS X Server 10.5.8 Unlimited client

12 GB DDR2

Rocketraid 2320 running a raid 0 and a raid 1 array

Rocket Raid 4322 running one 8 drive array

Firewire 800 Pcie card

Nvida 6600

 

 

 

 

I have a failing LCS on my quad 2.5 server. CPU A cores run ten degrees hotter than CpuB at idle and jump up to 70C under moderate load.  Naturally, it is kernel panicking at least once a week. Maybe I will clean the entire LCS system someday and fix it right but, in the meantime, I remember there was a version of Chud tools that would allow you to shut down one CPU. I don't remember the version. Does anyone remember the version number? A hint as to a place to get a copy would also be great as I could have sworn I had a copy but now that I need it.....

PowerMac, Mac OS X (10.5.5)

A:

I just installed the full X code package for 10.5 which included the developer tools and then reinstalled Chud tools but the Hardware control for the gpu "nap" function still does not show up under hardware tools.

    Hi,
    I'm not sure you can disable CPU A, but you can disable the second CPU B...

     

    You might try this also, thanks to old comm guy...

     

    This can be done in open firmware,(boot with cmd+option+O+F held down).

     

    setenv boot-args cpus=1

    reset-all

     

    As an emergency procedure you can slow CPU speed to 50% which will lower CPU temps by...

     

    System Preferences>Energy Saver>Options tab>Processor Performance>Reduced.

    Yes, I knew about the OF command to limit the cpu to one but, like you, I remember that affecting CPU b only. I found a copy of Chud tools 3.5.2 that talks about the option to shut down Cpu/s in its documentation but there is no app for it in the hardware tools section so I may not have gotten the full download or that is not the right version for the G5.

    Do you have Developer Tools for 10.5?

    Sorry for late reply. That is a good point. I have been sick but I will look and see if I installed it. I think I used to for single user stations but not for my server.

    Actually I do have the CPU preference panel installed now. Sadly, I don't think this will help as CPU A core 1 is the hottest and that one seems to be the one you cannot turn off by default.

    Have you tried Reduced Processor yet?

    Sniff,  Yes, I am reduced to that option I think. Running at half speed keeps the temps low enough for me to work on fixing a failed raid array, recovering its data, and beginning to think about migrating to a new machine. Sad, as with a custom patch for the bash vulnerability 10.5 server was the last fully functional server OS.  Fixing the LCS on this machine would be too much effort for anything other than a longer term personal project. It isn't leaking so it could be sedimentation, or blocked radiator fins, or a failing pump. I am a bit surprised that it was CPU A  cooling that went as traditional people wigged about CPU B running fast even back when there were the latest and greatest. It could be dried thermal paste on CPU A as well I suppose.

    Yes, likely the thermal paste has gone bad also, which I believe gives out on the most used CPU first.
