does you card still downclock to 150 and 300 or something for "power saver"? doesnt that reset and mess up all your settings? does gpu-z still say that crossfire is enabled?
Im only using 1 card, so no crossfire here
And yes it does still throttle down. As I type this my card is at 157/300
I didn't flash my card, just fixed AMD GPU Clock Tool so that I could go over 775/1125mhz Simples.
