On the way home stopped by Fry's, picked up a 1 Gig stick of PC3200 and one of the Hitachi 60GB 7200 RPM drives. Got home...grabbed my favorite plastic spatula and had the thing open in about 5 seconds (without stress I might add, and no marks or broken tabs listen to some of these peeps talk around here you'd think opening one of these things is more difficult than developing a vaccine for AIDS or was cheese easy!)...popped out the old RAM...removed the drive cage...took out the fan...removed the old Hard drive and installed the new one...put the fan back on and reinstalled the drive cage...and had the dang thing completely put back together...did I mention this was all done in under ten minutes? So...if you're a hard core tinkerer, overclocker, PC builder, techie, complete nerd, or whatever you want to call yourself and you're thinking that upgrading the mini is difficult...well, let me put your fears to's a no-brainer! Mine's upstairs right this second getting OS X installed on it.

This is my first mac....and so far so good. I'll be doing the Overclock bit on it soon (I'm only going to go to 1.42)...I'll keep you all posted!

Quick question though...what's the best way to get a Win2K user moved over to a MAC? Are there any wizards or tools that automate some of the workk that needs to be done...or is it just a by-hand thing? TIA
Overclocking huh?

I wish you luck, we've successfully OC'd about 11 of them, and broke 1 so far :closed:.

Also, recent speculation proposes there is absolutely no architectural difference between the 1.25GHz Mac Mini model and the 1.42GHz model. The only difference is that Apple just used a different PLL_CFG pin resistor configuration to increase the CPU multiplier - something that you could very easily do yourself.

If you aren't skilled at desoldering, I suggest you find someone who is. The resistors are EXTREMELY small, and you will definitely need a good magnifying glass and a steady hand. Despite what’s being said, most of the people that take their Minis to 1.58 don't have any trouble with the Altivec routines. All 11 of the of the stock 1.25GHz Minis we had have been successfully brought up to 1.58GHz with no problems.

There is no need to resolder/solder any of the MicroSMD resistors (Thank god!) because they are set to Zero Ohm anyways (essentially making them jumpers :mad: ), so all you need to do is bridge the pads with solder.

Believe me its well worth it, you WILL notice the speed difference.

ASP (Apple System Profiler) will report your 1.58GHz G4 at 750MHz, not because there is something wrong with the chipset/proc, but because ASP is inherently flawed and actually quite stupid. It rates processors based on a code lifted to it at system start up - it locates the code in a table of predetermined G4 specs, and just displays the string in ASP. If it receives an unknown code (there is no such thing 1.58GHz G4 at the moment) it defaults to 750MHz. But you can actually edit the table yourself with Interface Editor in Developer Tools to get ASP to properly display the correct speed.

Also, if you want be on the safe side, go ahead and throw some AS5 or Ceramique on the CPU to keep it extra cool. I actually haven't done it on any of our Minis - and the Motorola G4 is spec'd to be able to run at 100 C..... but if you are one of those extra cautious types, feel free to throw some on, its not hard.
