I bricked my gigabyte 7950wf trying to flash the bios from fz1 to f43 using atiwinflash.
When I boot up my monitor just goes into sleep mode and boots into windows with no display.
I have to disconnect the 2 x 6 pin leads on it and switch to my mobo dvi connection to get my monitor up and running.
Any suggestions to recover my 7950. I will not be able to try any as off to work in a minute.
Damm you gigabyte I only got you were supposed to havee lower voltage than the vapour x.
 
Does your card have dual bios switch? if yes then just flip it to the good bios to boot into dos, switch back to the bad flash bios and reflash back to the good bios.

If you don't have dual bios do you have onbaord gfx?

Well you can boot via the onboard gfx enter DOS, and then reflash the gigabyte card np

That's a stand recovery procedure for bad flash - if you do plan on testing out more bios's just remember to get the correct bios for your cards ram, many newer version's of 7950 and I suspect 7970 are being shipped with Elpida instead of the old Hynix ramchips.

Gigabyte offer an official bios flashing tool, use that next time. Details on their website.

Is there a guide you could provide/link for the above process.
I also dont understand how I can reflash if I have to disconnect the 2 6pin plugs as 7950 not powered up but in mobo slot and put my monitor onto mobo dvi.
Also didnt realise that they were being shipped with different ram ijust got the bios off gigabyte site. How do you know what ram is installed.
Thanks
Sorry for the n:O:O b questions.
 
Firstly you don't need to disconnect the 7950 at all, many users here have both the onboard gfx and the 7950 together via dual screens, igp controlling one and the 7950 the other etc etc.

Secondly ignore the different ram stuff I was referring to that as something for you to consider once you had recovered from your bad flash.

Now did you make a backup of the original bios? if not do you remember what your original bios version was? if so download it and follow this procedure:

Vga cable plugged into the motherboard as you will be booting via onboard, the 7950 must be plugged in and powered up, enter atiflash and flash the 7950 with the correct bios, once the flash is complete swap over the cable and if its successful you have recovered from a bad flash.
 
Last night the monitor just went into sleep mode with the 7950 connected and the monitor connected into the onboard. Is there a setting in the bios I need to change in order to boot using the onboard?
 
You have the Asrock Extreme 4? having checked online its an Z77 board so yeah you have an option within the bios to use igp or what ever its called to activate onboard gfx.
 
That's fine I'm assuming the all Z77 have the feature as standard so it will there just probably worded different, let us know how you get on, don't panic thou I'm pretty sure that card is recoverable :)

Are you sure there is no dual bios switch, i have 2 of these cards both with the switch.

I will double check for dual bios switch tonight. Will have to remove the gpu as cant get in to see because of cooler. Mini itx becoming a pain as have to remove cooler most of the time to carry out maintenance.
 
So i just flashed both of mine to F43, 1st card was on F42 2nd was on FZ1. I have flashed both Bios on each card and i can confirm that i seem to have full voltage control

+1

My FZ1 flashed to F43, used ATIWinFlash though. I have 6+6 pins. I have full voltage control.

Others are having trouble flashing and unlocking voltage. Not sure if there are some different pcb/revisions out there.
 
ok i found the dual bios switch and booted up in 2nd bios the switched back to bios 1 and tried flashing back to original FZ1 BIOS

atiwinflash -f -p 0 R795W3GD.FZ1

I Got the following message rom not erased?
 
Just a thought. How do you know you have FZ1 , have you checked the bios number in GPU-z or are you just assuming you have FZ1 due to 1000 clock speed.

There is apparently a new 1000 MHz bios - FX0 which is hardware voltage locked. This card has trouble accepting other bios versions and even if you flash it they are hardware locked. The original FZ1 cards were only locked via the bios, so flashing them unlocked them.
 
electrician when i flashed i used the command "atiflash -p 0 romname.F43" please note is used atiflash from a bootable usb
