In that case, you must make your research properly before flashing. Check if the BIOS you want to flash is compatible.

Also, no need to clear the motherboard CMOS before flashing. The GPUs bios is like the card firmware. Just ensure you have a stable system before flashing, you don't want the PC to crash while the BIOS is during the flash process

If you fail while flashing and the BIOS #1 is now corrupted and you can't boot into windows using that BIOS, there is a way to repair it.

-Turn Off PC
-Put the switch back to BIOS #2
-You restart PC running "Locked" BIOS (#2)
-Under Windows: You flip the GPU Bios switch back to #1
-Proceed to a normal flashing of the BIOS
-BIOS#1 is now repaired

OK, thanks for responding

Bye!
 
Amazing guide thanks so easy to do

My 7870 Tahiti card was giving me headaches with the low performance and lots of stutter, note to everyone with bios version .031, flash the bios this version is terrible.

Massive thanks to this guide

Unfortunately, I don't have this expertise.

I believe you can use ATIFlash for this, it will flash in the DOS

I missed this: "( If you only have one BIOS chip on your card, flash the only BIOS at your own risk )"

I flashed with a bios recommended in an earlier post which bricked the card. I did backup the original BIOS and managed to boot back into windows in the integrated GPU, but both atiwinflash and atiflash (via usbboot) report that there is no valid adaptor.

Help?

GPU-z is also reporting some really messed up card info: -

Thank you!

I'll be making a backup of them now.

Thanks Karlitos,

Used the BIOS update steps at post one on this thread to successfully flashed a GV-797OC-3GD Xfire setup to the GV-797TO-3GD Ghz BIOS. Update was smooth for both video card with alternative use of the 0 and 1 in the DOS command. CCC (CAT 3.1) did not boot following system reboot after the BIOS update of both video cards. (CCC did not recognize the updated GPUs).

I then uninstalled CAT 13.1, re-booted, re-install CAT 13.1 and then re-booted. Everything worked fine thereafter.

Thanks again for the great AYIWinflash guide....

I'm glad it helped

But keep in mind that when you flash BIOS, the system will believe you changed the GPU card with another one, so uninstalling and clearing the regedit is very necessary.
 
Would I be able to flash my bios to a 7970 even though it doesn't have the same I/O ports (like 2 DVI and a displayport)? I'm also confused if it's a 7970 BIOS or a 7950 BIOS because the title says 7970 but the image shows a 7950 (http://www.techpowerup.com/vgabios/126754/his-hd7970-3072-120816.html). Let's say I flash it to a 7970 925/1250 BIOS, will it be any different from a 7950 925/1250 BIOS? Thanks

NO. I bricked my 7850 HD by flashing with the BIOS of a 7870 HD from the same brand. It has been out of action now for over a month and still waiting for stuff to arrive from China so I can attempt to fix it before attempting an RMA. Huge pain, don't do it.
 
The wondrous Gigabyte's utility along with my own stupidity have managed to brick both BIOS...

I fixed the unlocked, but what can I do for the locked BIOS? No chance to fix it within Windows? Any specific command that could reflash if I turn the switch to position 2?

And since it's locked, why the freakin' Gigabyte's utility has broken it; damn it.

EDIT: LOL ***? I did exactly what you said on first post and it worked perfectly... I just flashed the F43 on the locked position ( broken BIOS ) and currently it did boot normally!
 
If I brick my 7790 with some modified BIOS will I be able to flash the original BIOS back onto the card if I boot with the integrated graphics on my A-Series APU?
I was just thinking that it could work similarly to the method of using the BIOS switch on the 79xx cards to boot when the modified BIOS didn't work
 
I tried this last night and all went well. However, once flashed (and with all drivers and oc software reintalled) I was getting lots of random freezing during games for 5-10 seconds at a time. Crashes here and there too. Plus AB suggested I was getting anything but constant voltage:



Any ideas?
