Resolved 1.33 GHz Mac Mini

[Wild Hare]

A question for those that may have one of these specific, stock G4 Mac minis.

1.33 GHz Mac Mini ONLY

Q: Is there a resistor present at the R52 location (under the heatsink)?

Resistor location red-dotted here on a 1.25 GHz Mac mini.


And if you’ve ever removed (or tried to remove) your G4 Mac mini’s heatsink, you might try this:

Easier heatsink removal, with a nylon spacer and steel pin from the backside.

The 1.33 GHz G4 Mac mini does not have R52 present. Confirmed now by three individuals.
Thanks!

Resistor R52 not present with frequency 1.33 GHz, Rezistors R351, R355, R358, R362 and R52 are pullup/pulldown rezistors for setting PLL_CFG signals - i.e. CPU frequency.

See this link: Mac Mini G4 and what to do with him.
Article is in Czech language, look for part 4.2 frequency configuration

Thank you @sailorMH very much for that link. Extremely informative and especially concerning recorded temperatures.

Asked about the 1.33 because it had been suggested that by alone removing R355 & R358 and adding R362 & R351 that both the 1.33 GHz AND the 1.5 GHz could achieve 1.67 GHz, ignoring R52. (When it is necessary to remove R52 from the 1.5 GHz mini to attain 1.67 GHz.) I also wonder if the adapter you pictured was the MCA004 V1.3 or the AS331 V1.5? I can no longer find the AS331 V1.5 but have been told that the MCA004’s work equally as well. (Which has not been my experience, although they appear identical.)

I can no longer find the AS331 V1.5 but have been told that the MCA004’s work equally as well.

My version is the top one - MCA004 V1.3 and worked well ;-)

I tested it successfully, but at the end I take one 44-pin IDE-mSATA adapter + mSATA SSD - it is smaller and nicer

 

[Wild Hare]

Yes. I also have changed now to the mSATA adapters. And I prefer the half-height version, thinking they allow more cooling air circulation. Even as some believe that the JMicron chip located under the mSATA will cause more heat to the mSATA. *Not too bad as Fahrenheit temperatures were taken here after 15 minutes runtime.
