I would but now even more weird, the 2nd video card won't change from 300mhz memory clock. like it's stuck. It was working fine and actually started doing 26mh/s just now then the pc crashed, since it's been back up, nothing but stuck at 300. Tried reinstalling the drivers but no dice. Gonna try reflashing it again to see if that fixes it.
That happens when memory overclock fails. You need to manually modify the bios because every card is different. Maybe one card will be fine at 2150mhz mem freq and another will crash at anything over 2000mhz.
