Hello, after a week playing with an iMac G4 800 that I acquired, I was able to SWAP the CPU for an XC7455@1333 and keep it stable at 1.3GHz. I'm not going to go into much detail about the explanations because I've been writing on my blog for a few hours now and I already have symptoms of dyslexia
, but I can tell you that this has been the maximum stability that I have been able to achieve, and to do so I have had to modify the Vcore. Here you have the whole explanation, in my native language, I live in Spain. Any questions that remain with the translation I will resolve.
