Title: Overclocking MAC Mini from 1.25GHz to 1.5GHz
Post by: amiman99 on May 29, 2012, 01:13:57 AM
Any one with Mac Mini and OSX?
I was wondering if there is any significant speed difference viewing Youtube videos or Flash games from 1.25GHz to 1.5GHz?
So far I'm using YouView which is better then native Youtube site, but I found this simple overclocking video http://www.youtube.com/watch?v=ZSSsUvmky1A&feature=related and I'm thinking to do it, but my question is, is it worth it?
Any feedback is appreciated.

I have used a macmini with osx and i couldn't play full screen movies. But i believe if you use Mos or Ubuntu it would work better (haven't tried yet) . Personally i would try that first before messing around with the hardware.

The hardware mod looks simple enough, but considering the size and spacing of the components on the board, I would not want to attempt it. I don't have a mac mini but from the looks of the video, these are not normal resisters, but smaller. If you are very experienced with board level repairs okay, otherwise its quite a risk I think of frying something...

I've done board level repairs and replaced components on amigas and older pcs but the components are spaced alot bigger than this kind of tight compact board... Also, you can get a 1.5ghz mac mini g4 for 200$ or less on ebay usually. To me its not worth frying one for 200$

I already have Mac Mini 1.25GHz, but wanted to know if is worth doing it to gain visible speed.
When you use YouView software for PPC G4 it actually works very well in full screen, but the flash games are very slow on 1.25Ghz, so I need to know if 1.5Gs would be better.
This Mac is my kids PC to play around until I get an Mac Mini Intel as a replacement.

I think the performance improvement will be negligible, and the risk of damage from the modification makes it not worthwhile. YouTube crawls on my 1.5GHz PowerBook - such is the modern, bloated, Flash-based internet.

I'd personally just get a 1.5Ghz Mac. They have more video RAM anyhow. MorphOS and OSX suck balls when you are stuck with 32Mb.

@amiman99

What about using MorphOS? Playing 360p content on MorphOS will take about 30% of your 1.25GHz G4 with Odyssey in overlay/fullscreen mode at most. And 720p is actually watchable on 1.5GHz machines.

I have been waiting till g5 support and faster speed powerpc macs are supported before buying a mac for morphos myself.

I want an every day amiga, not a toy that requires I still have a windows or linux pc next to it for other things...

AROS is okay for now, but I keep thinking about getting a morphos machine.

If it won't run all aga games well, or won't do youtube right its no use to me.

When I get Mac Mini Intel then the G4 is mine to mess with.
I was actually planning to get the OS4 installed on the Mini, but that's another story, unless someone have done it and can share experience doing it.

@Matt_H
Good to know that 1.5Gs is still not good for youtube, save me some time hacking it.

Here (http://www.amiga.org/forums/showthread.php?t=34069) you will find lots of info (scroll down a bit to the links), including instructions with photos from someone who OC'd his 1.25GHz Mini to 1.42GHz (which he found to be most reliable with no heat issues)...

I have a 1.5Ghz Mac Mini and the frame rate watching flash videos on any web browser(even HTML5) is pathetic and practically unwatchable.
If i were you i wouldn't try that hardware hack.
Instead try first MaTubes(http://www.macupdate.com/app/mac/28608/mactubes).
With this you can watch youtube videos with ultra smooth frame rate.
For other video sites try Vlc's "open network" function.

I was able to snag one MAC Mini 1.5GHz Intel Solo OSX10.5 for around $150. This thing is pretty zippy, plays youtube in browser pretty good, boot under 40 seconds from cold start,not bad.
I ordered 2 Gig RAM and 2.0Gig Core2Duo CPU for it, lets see how it runs after the upgrade.
When that's done I may have to play around with MorphOS on my old Mini G4.
Now..., what do I gain by installing MorphOS? Apart from looking like AmigaOS? any native aps, video editing sw?

My real goal was to install AmigaOS 4.0 on it, I see the videos on youtube, so it looks like is possible, it there anyone from here who was actually able to install AmigaOS 4.0 on their Mac Mini?

Completely impossible on an Intel machine. The 1.5GHz Mac Minis running OS4 are G4 machines running a leaked alpha version.

I think there was about one model of MacMini G4 that would boot the leaked OS4, but it was missing things like sound and networking.  Much better off with MorphOS on the G4 unless you were just looking to boot OS4 for fun.

Uhh Amiman, the day you succeed with that is the day that 21/12/12 is the end of the world, meaning that you can't even do it because of architecture differences. And the Moana bootloader is virtually useless
