Hi, basically what title says. i'm using furmark to stress the gpu and hwmonitor to look at the voltage. it goes from the 1068mv i have it set to the 1150mv it comes by default, then back at 1068mv.

been thinkering with the amd software for a while now and can't seem to find a solution. any ideas?

I have only used the Radeon software to change the settings with core max and power percentage. For my 580 I have noticed once I apply the settings the first time I can not change it again without restarting the computer. My newer AMD cards can be tweaked without needing a restart.

thanks for the answer but i dont think it relates. it did show whenever i changed something. is just that voltage would go to default for a sec then go back to 1068
