girino, do you plan to release an update for x13 algo? I tried the other free version, but can't mine with it because the rig locks up after 8 hours requiring a hard reboot. All my cards are 270 or 270x and I've seen others with the same card have the same instability issues with the free version.
I was not in my plans. I am still working on improving x11 algo. But if there is enough people asking for it I can try a fast port of the x13 algo.
