G4 MDD 1.25ghz motherboard transfer

If I have a Mac G4 MDD with a 1.25ghz processor, will it work on a Mac with a
1.0ghz motherboard? Thanks

Yes, you can swap motherboard AND processor module (together) from any MDD to another MDD.
Also, in your case, you should be able to swap the processor module alone since the 1Ghz and 1.25Ghz boards should both be running at 167Mhz. (Edid: Oooops! Glad I looked that up. Not all did. Check system profile if you're not sure. Some shipped with 133. Either way, it can be done, but adjustments will need to be made if the timings don't match.)
We're talking about two MDD's, right?

  • Power Mac G4 MDD: Swapping out motherboards

    I have two G4 MDD's. An FW800 dual 1.25 GHz which just blew the power supply(the 23 pin connector fails to get 25V). And I just bought a used MDD 2003 which is, so far, running fine.
    I have a reasonable amount of electronics know-how. And I'm learning to do my own PowerMac 'tech' work since I got the FW800 two years ago.
    So, how do I swap the dual 1.25 board for the 2003 single 1.25 board without 'winging it' into disaster.
    I will appreciate instructions.
    Shamus

    I've done many power supply swaps and removals.
    It's easier to just swap the power supply.
    However, if you've gotten this far, why not stick with the original cpu and logic board.
    On the other hand the other logic board may work as it has a 167 bus as well.
    I personally have swapped dual 867 cpus into fw800 motherboards from 1ghz units as they are both 133 bus. Also used 1.25ghz logic board to replace a dual 1ghz cpu logic board as they are 167 bus each.
    Still say if you got this far just replace with the originals.

  • Power Mac G4 MDD 1.25GHz DP often completely locks up in the first few minutes after booting, sometimes with the spinning beach ball, normally with a very high pitched whining noise.

    Over the last few months my Mac has developed a worrying habit.
    Within the first few minutes of starting it up (perhaps on average about 50% of the time) it will completely lock up. This may happen at the Log In screen (if I start up the Mac & then leave it for a while) or during normal use.
    Often the first symptom is a very high pitched (but quiet) whining noise that seems to come from the loud speaker on the front of the Mac. The pointer may freeze at this point, or it may still be moveable for 5 or 10 seconds before it freezes. It sometimes turns into the spinning beach ball during this. Once locked up the only way I can restart the Mac is to hold down the power button on the front for a few seconds to completely reboot the machine.
    Once the Mac has restarted, it usually behaves normally, almost always for the rest of the day. The initial lock up & resulting restart only normally seem to happen the first time I use the Mac that day.
    The only peripherals attached to the Mac (apart from the display, keyboard & mouse) are an ADSL modem, a USB printer and a pair of Apple Pro speakers, and this setup hasn't changed since long before the problems started, so I'm confident that I can discount the peripherals causing problems. I doubt that unplugging the speakers, for example, would have any effect.
    I've run Disc Utility, OnyX and DiscWarrior without anything major cropping up. My instincts (I've been troubleshooting Mac problems for 16 years) tell me that I have a fundamental hardware problem, possibly with one of the 4 RAM DIMMs installed.
    The RAM configuration is shown in the attached screen grab.
    I'm considering removing one DIMM, running with 1.5GB of RAM rather than 2GB for a while, and repeating with a different DIMM removed each time until I can hopefully isolate the dodgy DIMM.
    Do people feel this is a sensible approach, or should I try something else first?
    Many thanks.

    Sometimes visual inpection will show bulging tops/sides., my guess is if it is it's most likely in the PSU.
    Possible cheap fix, You can convert an ATX PSU for use on a G4...

  • MDD 1.25ghz stuck in safe mode

    so far these forums have been extremely helpful. I hope this trend continues. I tried adding two 512 ram chips and a Belkin USB 2.0 5 port pci card when everything turned into the dogs breakfast.
    As I type this, the side is open w/machine running (fan ablazing). .Grey screen, stuck gear. what gives?
    One stick (512) in J21
    All other ram removed
    PCI card removed
    WD Caviar 250G is set to cable select and is first.
    Seagate - cable select, second
    I have not tried a PMU reset.
    The machine was given to me by a friend and operated fairly well for the last year. Just a little slow, and I wanted to add a audio interface for music recording which requires the USB 2.0.
    I have learned that the original owner did not have either of the HD's set to cable select.
    Originally there were two 256 sticks in J21 & J23.
    when I added the two 512's & the pci port i felt really good, things seemed to be humming along...until they weren't.
    I started by taking away, switching, trading the sticks around and things got worse. Then i went through various HD configurations, including two smaller ones from older G4's.
    My Ram chips are;
    2 - Nynex 256 PC3200 DDR 400 MHZ
    2 - *looks generic: 2X 512MB 1GB DDR SDRAM PC2700 PC 2700 333Mhz 184Pin
    (I got these on ebay, and i just checked...the seller is no longer listed. I hope that if this is the problem, it is not lethal).

    Probably a new thread.
    But as long as you asked. i think i fudged the back up process. Because of a lack of confidence in my HD's I ended up backing up my home folder (w/the little house icon) into a zip file.
    It's been crazy trying to get that open. Finally, after reading forums, I acquired the "Unarchiver". That seemed to work to some degree, however, i'm missing a lot of documents.
    Currently, I am attempting the use of Stellar Phoenix to try and find those.
    I would like to clean my secondary drive when all is said and done and start over with that as the destination for Time Machine.
    One of the tricks has been that the secondary drive (I think the original 80gb that came w/MDD new) still had my buddy's name and password in it. Trying to unravel that mess (He finally remembered that he never assigned one, and I was apparently too thick to even try leaving it blank!) I have duplicate folders everywhere!
    Glad you asked, eh?
    (btw, you've been very helpful. To return the favor, I should say that I'm good with dogs and work for a large animal welfare org, so if you need any help in that area...by all means).

  • G4 PowerMac (MDD - 1.25Ghz) and no gigabit ethernet

    I have a problem with my G4 MDD. It will not run gigabit ethernet. I've used the cables, airport extreme base station with my PowerBook with no problem. The MDD will not run 1 Gb!! 10/100 are fine. Manually forcing 1Gb doesn't work - neither does autoselect. I am running 10.4.11. Tried it with Leopard and that doesn't work either.
    Anyone seen this? Are there any issues with the machines and 1Gb?? If not I guess my machine has a bad ethernet port and I will have to run at 100Mb (kinds slow for SAN disks!)

    Hate to disagree but..
    And I stand corrected. I just tested my MDD here at work, set to Auto-configure the Ethernet port which System Profiler reports as being 1000BaseT/Full-Duplex. Copying a 1.7GB folder took 2:29 to the desktop; same folder copy to my G5 took 2:07. I'll attribute the time difference to the PATA vs. SATA drives in the respective machines.
    I might suspect a bad Ethernet driver limiting you to 100Mbps. Either try a different User account, or an Archive & Install of the OS.

  • G4 MDD 1.25 dual Motherboard Replacement Docs or Help

    Hi, all!
    I searched the best I could in the forums before posting, so if I missed a link to this, I'm sorry!
    I have a replacement motherboard coming in and even though I have a very talented and technical friend coming by to help, it'd sure be nice to have some instructions on removing the current motherboard and the subsequent install of the newer one.
    Mine is having kernel panics about 98% of the time on attempted startups and I've tried (along with the Apple Store Genius Bar) everything I know how to do or have Googled and read. I think it's perhaps a USB bus issue.
    I did manage to get it to boot from the Apple Hardware Test and everything passed.
    And, one of the USB connectors on the back of the machine is damaged, so I figure a complete motherboard swap should eliminate all possibilities except for maybe the CPU which seemed to pass.
    So back to the original query...are there docs somewhere to guide one in the removal of the motherboard?
    I run a recording studio with this machine and I'm dead in the water!
    Thanks in advance!
    Buzzy
    (I am looking into either a new MacIntel or possibly a used G5 to replace it with)

    Hi there.
    I found a couple of links that downloadable take-apart service manuals for the G4 MDD. They weren't as easy to find as I thought they might - but I've taken other G4's apart and the principle is the same even if the picture is a little off, lol.
    The first was the best site - sometimes though it didn't download the pdf when I clicked on it - took me to another tab then i had to click the little download link near the bottom twice to complete the download - but the guides are worth the trouble.
    http://www.eserviceinfo.com/index.php?what=search2&searchstring=PowerMacG4
    These are some other useful links I found:
    http://www.macgurus.com/forums/showthread.php?t=19016
    http://www.youtube.com/watch?v=uEfNH1DaJUo
    In general though, are you sure it is the motherboard causing the problem and not something like a stick (or four) of RAM? They are the most common causers of kernel panics. Been going through the same thing with a stick of RAM I bought for a G4 MDD 1.25ghz DP like yours - technically it meets all the requirements for this model - I've run multiple tests which all say the ram stick is good - but when it's installed, I start getting kernel panics, programs quitting, random freezes and such. When I remove it, it's much slower, but no panics of any kind.
    Good luck.

  • 1.25GHz MDD keeps freezing

    About 18 months ago I bought an MDD 1.25GHz G4 on eBay. At the time my employer was still running OS 9.2.2, and after a few months this G4 would freeze a handful of times a week. No mouse movement, no clock movement. I installed a new hard drive but the problem remained.
    I mothballed the G4 until I installed Tiger on it in October of last year (2007), I noticed the same problem. During the installation I encountered a couple of kernel panics. After install it would freeze up.
    I'e tried different RAM and have run Apple Hardware Tool CD and TechToolPro. Neither app has reported a problem with the RAM.
    Could this be a bad processor or motherboard?
    Thanks.

    Have you tried a different mouse?
    The original Apple Pro mouse cable frays in the chord just as it exits the mouse, over time, and shorts out causing symptoms similar to yours. You can't see the fray by looking at it thru the exterior covering. This can happen to third party mice over time too.
    Mine did it. I plugged it into a different port, so the chord exited the mouse in a different direction, and had very few freezes after that. Once I got over my frugalness (cheapness!) I bought a new one. Eventually it got to where I couldn't even work for more then a few minutes without a freeze.
    So, try a known good mouse to see if that's the problem.
    Don Archibald, a Level 5 here, said the USB ports on the keyboard (for you desktop users) are underpowered and can cause this problem also if the mouse is plugged in there. This can even fry the keyboard sometimes (happened to him). Try plugging your mouse into a port on your monitor or tower.
    If you still have trouble post back!

  • Does all 1,25GHz MDD share the same mother board?

    The real question is : can you test (for testing purpose only) a dual processor board from a (non working) G4 dual 1.25GHz MDD on a (working) G4 mono 1.25GHz MDD ?
    Thanks,

    For this particular issue, I found out that neither is the tool dumb nor is me. It's SVGViewer messed up with the firefox browser, after I rebooted the computer this morning, problem is gone.

    Flashing the ROM on a PC card to make it Mac-usable typically requires the process start on a PC. There are sites around that have instructions--I don't have any bookmarked at the moment. Google "flashing Mac video card" and see what you get. I got this:
    Google results
    The ATI 9600 is supposed to be a cross-platform card with ROM for both Macs and PCs. However, that only applies if the card is a retail ATI-branded model. If it was a card once sold with a PC, it may not be cross-platform.
    I've used only retail ATI cards or the cards that shipped new in a Mac, so my understanding of flashing cards is limited to what others have posted in these forums.

  • Power Mac G4 MDD - Has difficulty booting after shut down

    I have a Power Mac G4 MDD (1.25Ghz) that is having issues when it is shut down. The power button on the front of the machine does not start the computer every time. Sometimes it works, sometimes I need to wait a while before it will work. When the button is pressed, it does not light up or anything.
    I have noticed that if I sleep the computer it always seems to wakeup when the front button is pressed. But if I shut down the G4, is does not always bootup.
    I have also performed multiple restarts when performing software updates, and they always seemed to work fine.
    I have changed the Saft battery inside - it was at about .4v
    I have performed a CUDA/PMU reset using the button on the motherboard, and followed the Apple procedure. (disconnect power, and accesories, press reset button, wait 10 seconds, reconnect, restart) It did not restart right away, had to wait 20 minutes or so.
    The G4 has a new installation of Tiger, with all of the updates.
    I have not checked the PSU, but plan on doing that soon. Just seems odd that it only has issues when the machine was shutdown. Seems to start after it sits for a while, but last night I was switching monitors, and shut it down, switched monitors, and it would not re-boot.
    Any ideas?

    With the "sometimes" nature of the problem, it could be the front panel board, a much cheaper replacement than a PSU. An Apple tech told me that one way to test the front panel board was to find one of the first Apple USB keyboards for the original iMac. The early ones have a power button like the old ADB boards that overrides the internal board/button. He said that, should the Mac start reliably from the old keyboard, then there is trouble with the front panel board. The Apple model number for the USB board with power button is M2452.

    I have identified that the PSU is dropping the standby voltage on Pin 1. It does not do it consistently, but when the 25v is missing from Pin 1, the G4 does not start. After a couple of minutes, I can see the voltage return to Pin 1, and the unit starts no problem.
    Before I look for a replacement PSU (which seem pretty expensive), I was wondering if anyone knows if this is purely a PSU issue, or does the CUDA/PMU influence the standby voltages?

  • Power Mac G4 MDD won't wake from sleep mode

    I have a Power Mac G4 MDD 1.25GHz with a 15" Apple display and running 10.4.
    I can not wake the computer up from the sleep mode. It will not respond to the mouse moving, a mouse click, a keyboard key, the power button on the display or the power button on the computer.
    The only thing I can do is force the computer off by holding in the power button (on display or computer) and restarting the computer.
    The computer is set to go to sleep after 1 hour of no use (or the issue happens if I put it to sleep).
    Any thoughts would be great.

    This is for a Mac that won't sleep.
    Here is KB article HT1776 with their tips.
    Mine follow;
    USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.If you've set your Mac to receive faxes, it may not be able to sleep. It might also have a damaged preferences file.
    If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Receive Faxes On This Computer box.
    If that doesn't work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
    If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
    Hope this helps!
    P.S. One member here reported this (Michael Gleason);
    "I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
    Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB cards.
    Also, here is Apple doc.#305262 about PCI cards and sleep.
    tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
    After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
    Tristan Currier noticed this; "I have a Canon printer(shared) and my imac would not sleep. I opened up printer/fax in system prefs and noticed it said the printer was in use when it was off. Opened up the printer queue and noticed about 7 pending documents. Deleted them all and now it sleeps.
    Check the printer queue!"

  • Zip drive in MDD

    Now I'm trying to make use of some parts of my newly abandoned G3 B&W. One thing that's in there is a Zip drive (100MB). Is it possible to install this in my "new" G4 MDD 1.25GHz? There is a SuperDrive in there already.
    Thanks.

    The zip drive is recognized but not the super drive.
    That sounds like the jumper issue I mentioned to the original poster. The ATA bus that serves the optical drive(s) requires little jumpers on the back of each drive be moved about to set priorities on that cable. You cannot have two masters or two slaves, only one master one slave. Unless it's been altered, your optical drive should already be set to "master."
    This Iomega install document (a small pdf) shows how to set the jumpers on the back of the ZIP:
    http://download.iomega.com/english/manuals/english/en325401.pdf
    It's on page 5.
    Typical cabling suggests that the master device be at the end and the slve device use the mid-cable connector.

  • MOSX Server RAID on a MDD...

    Greetings to all.
    I have an '03 MDD (1.25ghz) that I'd like to install OS X Server to. As I did the same thing with my MP, I'd like to RAID the boot volume (mirrored).
    I can create the RAID array across the two 120GB disks in my system just fine. However, when I go to install Mac OS X, it says I can't install OS X to this volume and the RAID volume is greyed out (it does allow me to install to a single member of the 120GB pair I have, however).
    Does anyone know why this is? My server disk is 10.4.7 (UB).
    The fact alone that it will let me boot from a single 120GB disk proves that this will work, as the end result in a software RAID1 array is just multiple disks with the same data on them (at least as far as Openfirmware/Toolbox is concerned). I don't think the ROM has anything to do with software mirroring, and I've heard that other people have gotten this working on pre-MDD systems with no issues at all.

  • G4 MDD, EM "Startup Disk is Full, cannot restart"

    Hello, all.
    So I have a G4 with two hard drives(PowerMac G4(MDD) 2x1.25GHz).  I was loading some music via a flash drive and an error message popped up that said, “Startup disk is Full”.  I have two hard drives, one is running 10.4.9, the other was running 10.5.6.  I was working in the 10.5.6 drive when I received this error message.  I decided that since I received this EM and was experiencing other problems with this drive, that I would reformat it back to 10.5 and update it back up.  When I put in the install disk and tried to restart, I got the following Error message, “Startup disk is full, cannot restart computer”.  I tried a couple of times and cleared most of the junk off of my desktop, but still had the EM.
    So I figured since I have two drives, I would manually turn off the computer and restart it in target mode to load the 10.4.9 drive. 
    With the install disk in the computer, I turned off the computer, and guess what….now it won’t turn back on!  So apparently, the EM(“Startup disk is full, cannot restart computer”) was true and now my Mac won’t even turn on.
    Colour me dumb, but I was hoping that someone may have run into this before and might know of a fix to get it back on. So at least I can manage the damage.
    I started searching through the archives and found that I may be able to turn it back on, with another Mac(Kinda like a Jump start), but I am not familiar with the process.
    Has anyone ever experienced something like this?  Does anyone have a suggestions on how to proceed?
    Any help is appreciated.

    You held down the C key when you tried the installer disc?
    Have you tried starting in Safe Mode?  This may temporarily clear enough files to allow you to do a quick clean.
