Hello, I've just recently purchased my second Sapphire 6850 card to setup crossfire. I can freely use Overdrive to overclock the individual cards but what fun is that, the max core clock Overdrive limits you to is 850. I've tried using both Afterburner as well as Sapphire Trixx to overclock but it seems whenever I go past a certain limit (possibly Overdrive's 850) then my 2nd card, (GPU #2) is forced to that overclock and runs at 99% load constantly even at idle state. It turns out that way no matter what program I use, I debated on flashing the cards to a newer bios but I'm afraid to do so for warranty's sake. I'm not sure if it would help, can someone please tell me if this is a known CCC driver issue or something? I really was hoping to at least get past 900mhz core and 1150 memory...whatever 1.2 volts can give me.

Also, I thought I'd mention, when I overclocked with both Afterburner and Trixx I had Overdrive disabled in CCC so there can't be conflicts, I've tried everything :(. I would love for Rodney to respond too because he kicks ass, even if he just says hello.

Thank you guys
