So this is a puzzeler for me, for I've been using the unlocked 6950 card for over a year now with no issues on my older x58 platform. Put together my new z77 setup yesterday, everything turns on but found no video output on my monitors.
So after doing some basic troubleshooting, I randomly flip the bios switch back to the read-only 6950 bios and everything works fine... Did some testing by flashing different bios, but I was only able to get it to work if it's a 6950 bios, regardless of the position of the bios switch or version of the 6970 bios.
Does anyone know what can cause something like this? It's almost as if the motherboard bios knows that its a 6950 card and only allow it to work with a 6950 bios. The motherboard is also flashed to the newest bios.
Thanks for any input
