mods are fairly basic... and info for how to fix Hotwire function for software-voltage-locked models of ASUS 7970 DCUII isn't out there yet. There is info for other models of cards, but what to do is not listed for this specific model, so I had to remove and replace parts until I found which one worked (remove PR122, located under backplate). Once it worked, I tried on other outputs, or what I thought was other outputs, but no change noticed, and card functions fine. Before removing PR122, max via HotWire was a meager 1.125V, when stock is 1.1V.
That limited the card to 1070 benchable. now I can push over 1.4V easily, but over 1.35V crashes the card...normal stuff for 7970 now. At least I can OC the card to 1200 Mhz now with 1.325V.
And yeah...I like to dig into the strings at times, I use orange and yellow Tortex too.
