[GUIDE] Edit AppleGraphicsPowerManagement.kext to unleash nvidia's GTX 570/580 full power and save energy at the same time.

A HUGE THANKS to all of You

 

After a couple of months having problems with my PNY GTX560 ti on 10.9.5

I wasn't able to come back from G1 state, w the fan at full speed all the time, and the Die getting Hot

I was about to buy another GraphicCard.

 

Thanks to You all, I have modified APGM kext, and its like a brand new GFX !!!!

I'm not sure to really understand the settings, but it works great.

I made 4 tries mixing Camoguy n' Lyle M settings (big big  thx)

I'm composing music, I need full Graphic perfs for plug-ins, then, I need the card to get fan-noiseless !!

 

My 4 testing:

1: high: 25/75/90/100  low 0/75/90/98   Smooth ,  but a bit slow getting to higher states ?

2: high: 25/75/90/100  low 0/95/95/97   Some tiny lags, but less noise, more fast at lowering speed

3: high: 25/75/90/100  low 0/75/95/98   Slow as N°2 but more G1 states (High speed)

4: high: 25/75/90/100  low 0/90/95/98  A good one, Smooth more G1 states.  I stick to this one

 

I may try some high setting changes...

But right now, its just Great !

I forgot all about this thread. Seems like a lifetime ago. Anyway, a belated "you're welcome."
