Hello!
I used 2x7950 and Afterburner let me control voltage without problem. But after I plugged in another 6450, then replaced it with 6570 and connected my monitor to it, Afterburner wouldn't let me change voltage, (any changes in the configuration of AB does not change anything) I can only change core and mem frequency of these 3 cards, but no voltage. If I remove 6570 and connect monitor to 7950 the voltage can be modified again. I tried installing Asus Tweak, but it sees only 6570. As 7xxx's BIOS can be modified I'm looking for a way to change voltage. I'll be happy if you help me find a solution how to be able to change voltage on 7950 while keeping my monitor connected to 6570. Thanks in advance!
P.S.
I tried AB 2.2.0, the latest and some another version
Catalyst 12.6 and 12.8
I'm using win7 x64
p.s.s no affect with riva tuner and att
It's what I spotted in the AB window about video hardware information--
