Hi guys, My problem is this, I am running 2 HD4870's in crossfire mode(or I was), both from force 3D, both 512MB, but one has the DHT freezer cooler on it. I flashed the bios on both cards with a modified one(same bios on both cards). After that the driver started reporting an error that says there is no graphics card installed. I flashed both cards back using the original bios from the card without the DHT freeze( I only backed up one because I thought they would be the same). After that the card with the DHT freezer was dead. I eventually found a bios that brought the card back to live but now device manager shows it as a vga controller and installing any catalyst driver version causes my computer not to be able to boot into windows. So if someone can post the bios for a Force 3D HD4870 512MB with the DHT Freezer cooler on it I would be forever greatful.
