There are no miners that can natively change voltage of 7xxx cards. ADL doesn't support it. You need to manually change voltage with trixx or afterburner. I heard one can hex edit and flash the BIOS of the card, but thats too involved for me.
If a card crashes or you reboot the system, voltage for that specific card will return to stock volts and you will need to set it again with your program of choice. No way around it.

Topic: 7950 voltage reset? (Read 1191 times)
I have a quad 7950 mining setup that is hashing away just fine. windows 8/12.8/2.4/cgminer 3.1
My problem came today when I noticed one card stopped working and had to reset the system. Suddenly all my cards were cranking up the fans to 2x what they usually run at, hash rates were lower than usual, temps higher, and one card would always go sick/dead in cgminer.
I noticed the problem- I am using Sapphire trixx utility to set custom voltage / clocks, and have it set to restore clocks on startup / force constant voltage, but when I restart the machine my voltage automagically goes back to stock 1.25 instead of my preset 1.1. Is there a easy fix for this or will I have to just manually change my voltage back to 1.1 every time I restart the computer?
