But the stock voltage was 1.218 :X
But all is well, apparently there's nothing wrong with my graphics card. Apparently there's a common bug with my mobo where the PCIe slot stops recognizing graphics cards, and a simple restoring of the default settings fixes it. I updated the BIOS as well, since it enables my PCIe to work as a 3.0 instead of a 2.0 as well.
Amazinly I had the same prob, lots of people haveing this now!
Now I managed somehow to keep it like it is with the bios, after 3 weeks of despair.
Im afraid of upgrading the bios, and having all the same prob again.
