Well, R600 is overclockable without the BIOS updates, but not in CrossFire. The number of people with R600 crossfire is probably rather few. I completely understand though that these people wants to overclock the cards too, but then you should be mad at ATI for making sucky drivers in the first place, not because they've chosen to release BIOSes and flash utilities to a few chosen people. If the BIOSes were left to spread freely chances are that we would have a bunch of people complaining over black screens and cards not working anymore. This is not a good nor permanent solution to CrossFire overclocking, this is a highly temporary solution. Wait for real CrossFire overclocking instead.
