View Full Version : Overclocking Intel GMA950 in Macbook

For those with an adventurous spirit, there is software available now for overclocking the GMA950 in the Macbook.
GMABooster :: Download (Mac OS X) (http://www.gmabooster.com/download_mac.htm)

From what I have read, the GMA950 runs at 400MHz in the Mac Mini. In the Macbook it runs at 250MHz. Thus this little bit of code makes your Macbook run at 400MHz instead. Compromises would appear to be diminished battery life due to increased fan activity to keep the GMA950 cooler.

I'm not brave enough to do this to my Macbook as it is my main work machine and I understand that polishing a turd still leaves you with a turd.

I've used the PC version on my MSI Wind.
It does appear to give some (very minor) gains in 3D tasks.

Battery life and cooling shouldn't be affected too much as GMABooster does not raise the voltage to achieve the overclock.

Had installed this on a Travelmate 4200 running 10.5.1

It's a bit snappier and I don't notice any loss of battery life.

I'm trying to decide as to whether this is stupidly brave, or bravely stupid.

Well, you can revert the speed back to it's normal self with the same program.

I didn't have any issue with it, but then again, the machine I used was one that i'm stuffing around with.

I tried the other night, just a bit snappier (very minor). I wont play any games so I can't tell you really

I wonder if underclocking the GMA to 166mhz will increase the battery life much without breaking things?

MSI Wind owners using GMABooster have not reported any noticeable decreases in battery life when overclocking from 133Mhz up to 400Mhz. This is because the GMA950 always stays at 1.05v regardless of clock speed.

Any battery life increases from underclocking to 166Mhz will be extremely minimal at best, unless someone works out a way to lower the voltage (which would then be likely to causes serious stability issues).
