That's what i just did and decided to share with you this great news! Downloaded bios file of r7 260x 1GB OC from Gigabyte support website, downloaded atiWinFlash in latest available version, prepared files for simplistic flash, rebooted pc and everything works fine. Step by step... It wasn't easy to find trusted bios file of r7 260x with 1GB of memory, gigabyte support website seems to be very trusted on this kind of thing. When i found it decided to try it out, i'm very cautious person so i awaited with doing this until i will have any other gpu in case of failure(it delayed me few months xD ). When i was ready i prepared tool for flash - atiWinFlash. Created backup of hd7790 bios with gpu-z and with atiWinFlash (in the past i had some problems with .rom files created with gpu-z so decided to do one more dump with atiWinFlash, just in case). On first attempt i tried to flash card with GUI version of program but it refused with error message about mismatching device subIDs. So i was forced to force flash which is possible only from commandline version of atiFlash and that's what i did (atiwinflash -f -p 0 bios.bin). Awaited until it finished and prompted to restart, restarted pc. On boot windows gave me bluescreen (probably caused by loading new driver, replacing driver or whatever related to unexpected driver changes) but on next boot everything went fine. Just in case, reinstalled drivers, pc is working good so far. Here you can download files i did use to it and try on your own but remember to create backup first!!! Also you must be noticed: flashing vga to other model can fail so if you are trying to do this you do this at your own risk!!!! Of course i hope everything will do fine to anyone who will try it Ok, link here: http://speedy.sh/UdvxK/r7-260x-autoflash-utility.7z In this archive is everything you need, instructions included.
