I just installed an EVGA GTX 570 into my rig a few days ago and gpu-z is giving me some weird data. It claims my default mem clock is 1900 ghz and the current reads 950. It also displays the memory as DDR2 and not GDDR5. Also, there're all these "Unknown" entries that I can't seem to fix no matter what I do. What do I make of this? I've searched for other gpu-z readings of the same card, but so far I haven't seen anyone else that has this problem.
