Looking for a bit of expert knowledge before I get on with this. I flashed one of my 7970 bios to the GHz edition bios and then tried to flash it back, but it didn't work and now I've only got one working bios. How do I flash the broken bios back to factory condition? Do I just boot using my iGPU and a bootable usb and then type 'atiflash -f -p 0 oldbios.bin', making sure I've set my card to the broken bios first?
In theory you can use the second bios to reflash the first one there is no guarentee this will work though. Ghz bios uses higher than standard speeds not every 7970 will hit them safely, and a small reminder only reference 7970 bios can be flashed to ghz bios, if you have a even slightly custom card then the chances are your bios is not stock.
My card is reference and the GHz bios worked fine on it. I just felt like flashing it back to the original bios because the GHz didn't offer any real advantages. The problem is that flashing it back didn't work and now it won't boot from that bios.
I'm as sure as I can be. I just used the standard command. I.e. 'atiflash -f -p 0 oldbios.bin'. It seemed to work but then when I tried to reboot it wouldn't.
The first thing I tried was flashing it back with the original bios that I had saved when I flashed to the GHz bios, but that didn't work. Then I flashed it with a bios of a mate of mine who has the exact same card, but that didn't work either.
If you have another GPU, boot from that one and have the 7970 in a lower PCIE slot and flash it that way. Dunno the switch for ATIFlash but it can be done. Techpowerup has a comprehensive list of bioses Sent from my GT-I9300 using Tapatalk 2
The likely hood is your card is not reference at all despite what they may say and it has a custom bios hence every time you try to flash it fails. Even the same card may not have the same bios due to date of manufacture. I'd just go back to the ghz bios if I was you as you know it works.
Yeah that should be fine, I'm fairly certain there is a switch in ATIFlash for doing certain PCIE slots. Which 7970 do you have? Sent from my GT-I9300 using Tapatalk 2
Don't I just go with '0', which is the first slot by default? I only have one GPU installed (not counting my iGPU).
