GPU undervolting what app to use for this?

view story

http://forum.xda-developers.com – OK, so we have setcpu to undervolt. I'm doing this on my Note II and running 1600Mhz at 1200mV (all others -50mV) which I think is helping batter life. I watched an 1 1/2 movie and the battery only dropped 7% :highfive: Better than stock for sure Anyone know of an app that will let us undervolt the GPU? I remember there was tegrak, but the Note II is not supported. Also Stweaks or something? (HowTos)
