Undervolting r9 290x

[bmL]

Is it possible and if it is, is it proffitable. I'm trying to find some info on that topic but no success ;/
I want to undervolt it under linux. There is something about afterburner but there is no afterburner for linux.
Also in cgminer it does not display cars voltage.

Vas a tener que esperar al Kernel 3.13 que entre sus características aparece el manejo de voltaje de placas AMD.

You'll have to wait for the 3.13 Kernel handling of AMD plate voltage appears between its features.
