I got a Twin Frozr 4 Power Edition 7850. Supposedly the voltage is supposed to unlock, but in ASUS Gpu Tweak there's no option to unlock voltage, but there is an option to increase overclocking range. I've seen that people have better success with Gpu Tweak, but when I got 1050 on Gpu Tweak, then it's unstable but on Afterburner it's perfectly stable. Plus on Afterburner I can up the voltage because the Twin Frozr 4 is designed for Triple Over Volting. Is there a way for me to raise the overclocking limit on Afterburner, is it that I got a bad card for overclocking? Or should I wait for 12.6 drivers to allow me to overclock more?
