So I've since uncovered that the cards are throttled to 500mhz on the core and 150mhz on the memory.
Not sure why they've capped themselves.
Anyone had this before? How can I bring them back to life?
No overclocking app works. They're just stubbornly stuck at 500mhz
Should be driver problem, I have this problem too, sometimes my ASUS DC2 card acts the same as yours..
