Another update, I have found a CPU daughter card but it's only 867 MHZ, I can match the bus speeds easily by changing the resistors. but should I resist the logic board down or the CPU up?
It's not entirely clear if I will have to alter the voltages because it will need more current to be...
I will check out the page, interesting info thank you.
Though this evening thought I would check to see what the CPU’s are doing.
Wow one gets really really hot really quickly.
I would imagine that this is the problem, not perhaps the brightest way you check with a finger and no cooler...
The bend in the card isn’t much really after looking at it.
Cooler held against the heat sink makes no difference.
Fans on a hot boot come on right away on full and try to throttle back but only for a few seconds.
Frustrated!
So after some more testing I am sure this is heat related, I have double checked the thermal paste and reapplied, it was making good contact.
Though the CPU daughter card does have a bow in it, I guess from years of having a cooler pushing against it, perhaps this could be causing uneven...
I don’t know if this link will work, it’s a video of what’s happening.
Also swapped some dimms aroud to see if it makes a change.
It’s mental noisy!

I have messed about with the DIMMS, though I might try this again.
I got three beeps which I assumed was bad or incorrectly seated memory. Took them all out and got a single beep. So stuck with just a single which seemed to work fine.
Hi,
Yes I rewired it to match the pin outs but of course missed out the +25v for ADC.
I was gutted as I thought it would fix the issue, spend bloody ages messing with them pins.
Hi All,
I am a long time Mac user and was feeling somewhat nostalgic, the wife says I am having a midlife crisis.
So I bought myself some old G4 PowerMac's, the one that interests me is the G4 MDD dual 1.4 ghz.
I gave it a little clean and fired it up, and it worked perfectly, however, on...
