Well, it finally has been done, the MacMini has been overclocked. Leo Bodnar has figured out how to do it. The good news is that you only have to change 3 jumpers. The bad news is the jumpers are tiny!
Overclocking
Just like in any other Mac with 744x CPU, the speed is controlled by the jumpers. Here is the bottom of the Motherboard. Many years ago there were component side and solder side. Now I don't know... But before you rush into it, take a look at the size of the jumpers. Read 7447's datasheet if you are interested. Jumpers are located in the area directly under CPU.
| Speed | R362 | R358 | R355 | R351 |
| 1.25GHz | yes | yes | yes | - |
| 1.42GHz | - | yes | - | yes |
| 1.50GHz | - | - | - | - |
| 1.58GHz | - | yes | - | - |
I have settled on 1.42GHz speed for my original 1.25GHz Mac mini.
gave me some glitches in Xbench Altivec routines and very weird
behaviour at 1.58GHz - the speed was reported by the system profiler as
750MHz(?!) I would guess 1.42GHz mini owners may be able to get 1.5GHz
if they bother to try. Mind you it is only 6% increase so I am not sure
if it is worth it. Well, at least I have 1.42GHz now and it works
fine.
1.5GHz settings
Enjoy! |
