CPU Upgrades / Re: Mac Mini G4 Overclock just because its fun.
« Last post by Jubadub on April 08, 2024, 02:36:24 AM »So OS9 works worse on Mini 10.2? for what reasons?
Whoever manufactures and converts to 7448 is "herd", great guy, he usually helps me with my questions. I have some interposers that he sent to me. I'm really grateful. Without a doubt, I managed to raise the current and voltage limit on my Mini thanks to his advice.
I'm just an amateur, a big head, as they say in Spain "Master of many trades, few benefits." In the early 2000s I played a lot with the G4s, I had a pioneering blog in my country and I did many overclocks and mods. But I have many other hobbies and I change depending on the moment or concerns.
Since I don't speak English very well (I use translate a lot) it is difficult for me to understand how to patch the Mini's firmware to be able to run a 7448. But the main problem is acquiring a 7448, I can't do it, I have tried many times and it never works good. So I am limited to the 7447@1667, of which I still have 3 or 4 units.
I only show these achievements so that everyone can do them, I don't do it for praise or anything. And I put it on my blog because this way I make sure that the information is not lost. In recent years I have tried to collect a lot of information that was on forums, but most of it has been lost, especially photos. My blog is a time capsule, everything is preserved there, and I have the photos hosted.
For now I can't get a 7448? Well, it will be someone else who achieves achievements, it doesn't matter, the important thing is that they are made known and everyone can try.
I go through the issues found in the "silent upgrade" + our current port of Mac OS 9 for minis in this comment.
I wonder if "herd" is the same guy, my source wasn't registered at the time we were working together. I would love to get some interposer boards from him, just in case I can somehow get Mac hardware in my current country shipped in, or physically brought in somehow.
For acquiring 7448, you need to pinpoint the exact vendors/users on EBay and the like that reliably source all kinds of processors. I gave my then-current list to my interposer buddy, and told him how to get them for the best prices. I forgot all the details by now, unfortunately, but what I can tell you is that if you keep on looking, and trying different sites/people, you will find them. Most of them come from misc. devices that surprisingly used the 7448, so they got desoldered and sold as is. Much more expensive units usually come from brand-new recently-manufactured sources, since the processor shockingly was still in production back then (circa 2021, no idea now). Preferably go for the processor with the highest binning, for maximum chances of overclocking, as detailed in one of my topics in MacRumors PPC.
If I could do it, you can do it, too.
I understand your struggle with the language barrier, but trust me, "where there is a will, there is a way". I survived completely alone in Hungary for 9 months without knowing a single drop of Hungarian, and nearly no one there knew the languages I knew, yet I survived that whole period, and was able to communicate, and parse some Hungarian language with time... "To live and to learn", as they say!Thank you for sharing your achievements! Like you said, it makes it easier for other people to try, and achieve the same. This includes me: I never modded or played around with the MDD anywhere near as much as I originally wanted to, and now I have no physical access to any MDD, but if by any chance I do someday, your findings will be of great help!
