Can't switch between multiple GPUs

I have two ASUS R9 270x, but in GPU Tweak I only see one card.
How to control voltage on the second card?
Moving mouse under GPU name not works.

Thanks!

does Not solve the issue. my 2x matrix cards i have no voltage controll with AB. only tool that i have had any success with so far is AGT. but i'm unable to select the cards i wanna clock. unless i enable crossfire.. but then what i use my cards for become useless to do

I haven't tried to O/C my cards or adjust the voltages but unless i am getting it wrong you can select which card to adjust, and clicking the displayed lock undoes it.

Click on the number to change cards between 1 or 2 or sync

I am in Crossfire with Matrix HD7970's Plat edt.
Rampage iv Extreme.....3930 i7.....32gb Corsair Vengeance....Thermaltake Water 2.0 Extreme....Matrix HD 7970 x 2 in crossfire....Creative Fatality Champion Soundcard - With front drive bay....Themaltake Toughpower XT Gold 1475 watt power supply.....Samsung SSD 830 512gb...Samsung 1TB HD x 2....Samsung Blu Ray drive....Samsung DVD drive...Windows 7 Ultimate....Thermaltake Overseer RX-1 case

the issue at hand is that when you have more than 2 gpu's connected it won't find it. or if you have the newest r9 280x matrix x2 it won't find em.

if i connect 2 5870 in crossfire i can change settings in gpu tweak. BUT that's when issues starts arising. crossfire destroy's my program.

Please fix this simple bug.. remove the "must have crossfire activated" flag or something

I have 2 r9 290. GPU Tweak detect the two cards. But when I change the fan speed, this only works for 1 card.... Can't even change the fan speed with Catalyst either... Looks like I will have to download Afterburner 😞
