Is E2-3000M APU GPU Undervolting possible?

post #1 of 5
Thread Starter 
So is it possible to undervolt the gpu on a AMD APU in a laptop to save even more battery life?

Right now i have the processor part of the apu undervolted with FuzionTweaker.

edit: Sorry I misread it. Not sure about undervolting the GPU side, but you might be able to lower it's clocks with K10stat( I *had* a C-50 netbook but never got around to messing with GPU undervolt/underclock).

Yup. I'm using K10stat for my A8, and it undervolts marvelously. 800mhz idle is running at .75V instead of .925, and max clock speed is running at 2100mhz at 1.0375V instead of 1500mhz at 1.0625V

Haven't had any luck with the GPU. The latest Afterburner beta doesn't work

So pretty much nothing has been found? I would love to be able to squeeze even more battery life out of this thing. Since the gpu part of the apu is always at .89 volts
