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! https://share.icloud.com/photos/0485xeYj5HcEwikcrMRl0w6pQ

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...
