Mac Mini G4 Overclock just because its fun.
indibil:
Hello, I am writing to you from Spain. I have a Mac Mini G4 at 1.42 that I want to use for OS 9.2.2 (Now I write to you from the Classilla browser inside Mac OS 9). I'm searching the internet and I can't find overclock resistor settings for speeds above 1.58GHz. My intention is to reach 1.67GHz, but all the photos on the internet are disappearing. Can someone post a photo of the resistor positions, for speeds greater than 1.58GHz? Thank you.

hello I'm come from china shenzhen, I find the Power10.2 Model is different from the Power10.1 Model
Power10.2 Model jumper set R351 R355 R358, is different from this article
https://thehouseofmoth.com/ppc-overclocking-station/#G4mini
Does anyone known all the new jumper set in the Power10.2 Model?
FBz:
If you have the 1.33 GHz model - House of Moth mentions a fifth resistor that he had yet to locate.
“To set the jumpers for 1.33GHz, a 5th resistor has to be located (as it needs to be removed).
With the 5th resistor, for now, permanently enabled, you can only configure for the 4 clock speeds shown above. A common belief is that the 5th resistor is always enabled and acts as a ground but that does not work as the 1.33GHz configuration needs that resistor removed. Comparing a 1.33GHz board with another G4 mini board should help in locating that 5th resistor. Once this is located I will update this page.” - House of Moth

So is there any possible to replace the CPU to he hign model 7447A, for example 1.5GHZ and 1.667GHZ and overclock again?
I bought the two model from ebay

@sonicsky Have you removed the heatsink from your PowerMac 10,2? (Actually a 1.33 GHz Mac mini?)
sonicsky's images
If you have the heatsink off, do you see a resistor @ R52?
