When it saved and rebooted i got logged in and it BSOD and everytime i would try to start windows it would just BSOD so i reinstalled windows without the 670 because it would BSOD during install. I installed W7 and download the drivers updated windows and then shutdown and plugged the 670 in. started it up and got picture so i kept going, when i tryed to install the driver it started telling me that there was a 7zip error and the file could not be read, so i retryed and it got past that point and then told me that the install failed tryed agian siad the hardware was not compatible. so i unplugged, and put my buddies 650Ti in and installed the drives no hitch and the card worked fine but needless to say my 670 is still not working properly and like i siad i get an image but its just a matter of time before it just bsod.
well if you have a second card this will be easy for you.
go get the Gigabyte 670 Co stock bios.
make sure the 660 are in the first slot in your mobo
set the 670 as a second card
make a bootable USB drive and put the stock bios in the USB. HERE
make sure you bios is set to boot to USB Primary.
make sure you know which GPU's is the 670 and use the following command.
Nvflash -4 -5 -6 rom_name.rom
you can boot to windows with a 670 as a second card.use the GPU-z to find the device ID and make sure you take a note of it and don't flash the 660 with the 670- biosEdited by skyn3t - 5/13/13 at 4:24pm
