I've been playing with my Mac Mini (not a hackintosh). I have it running rock solid at 2.300 GHz with a 1.225 GHz FSB and 1.225 GHz DDR3. Between the overclock and the 4 GB DDR3 and 320 GB WD 7200 RPM drive it's very responsive.

Unfortunately I can only overclock in Windows 7.

Question: Has anybody been able to find a utility that works in OSX?



Thanks in advance.

No doesn't exist!

There is GenericCPUPMControl for Hackintoshes only, I think. But it's more aimed to underclocking, and be aware you can easily mess up your OS and have to reinstall it if you play without knowing exactly what you're doing.

Does anybody have a clue why there are no CPU overclocking utilities for Mac OSX?

The only overclocking utility I know of for OSX is ZDNet's Clock (http://www.zdnet.de/einsatz_von_apple_maci...-39192217-2.htm). It's quite primitive, compared with Windows utilities, and reportedly causes one's system clock to run fast in proportion with the overclock.

I believe the reason the Windows utilities are useless is that they modify the BIOS, whereas OSX uses EFI; hence, loading OSX causes all settings to revert to whatever the EFI specifies. To overclock in OSX, one needs a utlility that modifies the EFI.

Given all the programming skill that's evident here, it surprises me that no one's tackled this need.

I don't know how the new mac minis are made, if the cpu isn't actually soldered into the logic board, you can try to do a tape mod. But if you do, monitor your temps and voltages constantly.

overcloking utillities doesnt change bios/efi

they reprogramming pll chip, as example - setfsb.

I have a few questions for you, if you don't mind. What was your Mini's original clock, 2GHz or 2.2GHz? Are you using the 32-bit or 64-bit version of Windows 7? Are you also overclocking the graphics card? What application(s) are you using to overclock? Thanks.

I have also overclocked my 2009 Mini 2.0GHz 4GB Ram 500GB 7200RPM HD. The results are in the image attached. This is my first overclocking job and I used the free nVidia Control Panel download to achieve the results. My "Windows Experience Index" went from 5.0 to 5.3.
