Undervolting Sapphire 7950 w/Boost under Linux

[eleight]

Hi everyone

Last 7 days I'm looking for a solution to undervolt my GPU under linux but I wasn't successful. I know some people did this under Windows using TriXX Tweak Utility.

Did anyone managed to lower voltage on any 7950 under Linux. My card has a stock voltage of 1.25V which IMHO might go lower.

Tnx

Both cgminer and atitweak failed. I remember seeing elsewhere you might be able to do it in Windows and then reboot to Linux.

If all utils fail, you always have a choice to mod BIOS.
Assuming the card has dual BIOSes, even if you flash something wrong it won't be a huge issue.

i know this is an old topic but did you end up finding a way to undervolt within linux?  I found this software have you tried it ? AMDOverdriveCtrl
