Q: Need help with thermal calibration for PowerMac G5

I have a PowerMac G5 - dual 1.8 GHz with 8 GB RAM (bought in 2004).  I am about to replace the logic board and have to perform the thermal calibration.  Seeing previous postings, I apparently need the ASD 2.5.8., or possibly 2.5.7. Does anyone have something they could send me?

PowerMac, Mac OS X (10.5.8), PowerMac G5 Dual 1.8 GHz (2004) 8GB

    Hi romko23

       I am very new to this. So pardon me should I act in a very noob way.

    I recently acquire a Power Mac G5 Quad (OSX 10.5.8) been using it for a while without any problem

    except the initial RAM is a bit low (2GB) so feel a little sluggish. So I decided to upgrade the RAM to 10GB. The machine

    then start to show some problem with what I thought to be overheat problem the 2nd LED near memory

    banks lit up and the machine either go to sleep or ask me shutdown very often.

      I include a pic below showing the normal temperature when I am doing almost nothing on it. The temp. can

    easily shoot up to (especially 2nd CPU) 70-80 degree C before the symptoms I described above happen.

    The fan is also incredibly loud.

      Is it possible that I may need to do a thermal calibration. Or if the seating or heat paste (does this model have something like this) that couple the CPU to the heatsink worn off/disintegrate  is needed to be redone?

      Either way, I heard that to carry out these steps I will eventually need the ASD software. Can you help?

       Thanks in advance, Utane

    Hi, & a warm welcome....

     

    Those temps are cgeat actully, no problem there!

     

    More rRAM will likely help a bit.

     

    See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...

    Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?

     

    How much RAM & free Disk space do you have also, click on the Memory & Disk Usage Tabs.

     

    Open Console in Utilities & see if there are any clues or repeating messages when this happens.

     

    In the Memory tab of Activity Monitor, are there a lot of Pageouts?

    Thanks for your reply.

        I did all the checks you suggested and found them all to be ok. I just upgrade to RAM to 10GB so

    no problem there. The Pageouts stays zero, no unusual high CPU or disk activity and no S.M.A.R.T error either.

     

    I notice the temperature of the 2 cores of CPU B are always 10-20 degree C higher than CPU A, in fact if I look at the history from the past 5 days (that's when I install the temperaturemonitor software), the maximum temperature did spiked up to 80-86 degree C. And that's what I suspected causing the freezed up and forced shutdown which lit up the 2nd and 7th LEDs just before it happened. After some research on this site I saw lots of people with G5 Quad reported the LCS module for the CPU B failed causing the overheating. I still need to open up my heatsink cover and do some checking, maybe try swapping processor card as many people did and perhaps re-applying of thermal paste for CPU B to see if it help to bring the temperature down a bit.

     

    Do you know if there is any link to G5 Quad CPU heatsink removal+re-seating howto?

    Ah, yes, you need to likely replace the Thermal paste on thr CPUs and flush/rebuuild the LCS...

    Thanks BDAqua,  

       finally had a look under heatsink cover, no leakage. I will check/re-apply thermal paste this weekend and see how it goes.

    Hopefully, it's not the well-documentd gunk blocking my pipe.

     

    Cheers,

    Hi, i have a power mac G5 late 2004 and i just replaced W/LCS but still have my old processors due to old leaking water blocks. What i need to know is do i need to run a thermal calibration if yes can somebody plz help me by telling me where i can get the softwaire.

    For those who need help with the Calibration. I am in Ukraine right now, so I can access my machine from far away if anyone needs help.

     

    Please all pray for us, its bad here.
