i second this.

unfourtunatly it sounds like you rushed this and didnt know/neglected that the card MUST be ati refference.

MSI may not accept an rma unless you play dumb, but even then they may not due to the common 6970 reflash fad.

Hmmm, so why can't I reflash the old bios then? My computer IDs it in GPU-Z.

I've read that another person who had the same problem with a non-ref was able to reflash it back successfully.

The problem right now is I need to bypass the ID-mismatch for winflash without using the cmd line.

Flash in DOS.

Sometimes forcing a 128k blank file (128kb of zeros from a hex editor) over what's on the card, then forcing the original bios back onto the card will help.

Can you give me suggestions on how to do either? I've never done it before.

thanks

Btw, here is the code for the 6950 to 6970 and 6970 to 6950 program:

@echo off

copy /b/y NUL %WINDIR%\\06CF2EB6-94E6-4a60-91D8-AB945AE8CF38 >NUL 2>&1
if ERRORLEVEL 1 goto notadmin
goto admin

:notadmin
echo This script must be run as administrator.
echo Right click it and select "Run as Administrator".
goto end

:admin
del %WINDIR%\\06CF2EB6-94E6-4a60-91D8-AB945AE8CF38 >NUL 2>&1

%~d0
CD %~dp0
echo.
echo TechPowerUp HD 6950 to HD 6970 Flashing Tools
echo *********************************************
echo.
echo The full article can be found at:
echo http://www.techpowerup.com/articles/...ng/vidcard/159
echo.
echo Please make sure the BIOS selector switch on your card is in the 1 position.
echo This script will *RESTORE* the original BIOS of your HD 6950.
echo.
echo Press any key to continue or CTRL+C to abort.

pause > NUL

cd winflash
atiwinflash -unlockrom 0

if exist backup.bin (
atiwinflash -f -p 0 FILENAME.bin
) else (
echo Backup BIOS not found, flashing a generic HD 6950 reference BIOS.
atiwinflash -f -p 0 FILENAME.bin
)

echo.

if ERRORLEVEL 0 goto success
echo Winflash reported an error in the flashing process, please watch any on-screen messages.
goto end

:success
echo The flashing process completed sucessfully.
echo.
echo Please restart your system for the changes to apply.
goto end

:end
echo.
pause







Is there any way I can edit the code so it only deletes the BIOS without installing a new bios? That way I can install a new bios without worrying about subsystem ID mismatch error.

The card isnt bricked , it just doesnt want to cooperate with the 6970 bios as its a non reference card .. u should of did mor research before you went and flashed this card .

I think the problem is fixable , download the original 6950 bios and use atiwinflash to reflash it .. should work , if not you will have to go the cmd route with a bootable usb and that should get it working again .

sucks to hear , i unlocked my 6950 to a 6970 no problem .. but i have the first revision of the pcb and its reference .. The newer 6950's i dont think can be unlocked anymore .

I agree with a few of the others. You need to make a bootable DOS flash drive, and use that to reflash it. I don't remember the exact way to do it though. But I "bricked" my old 4850 a while back. And flashing it back to the stock BIOS was a cinch with a spare card to use.

Well if you really think you bricked your card, I'll take it off of your hands if you can't RMA it. =D
post #20 of 55
I sure hope its not messed up beyond repair

I never tried to flash my single BIOS non-ref 6950

But I better get the overall simple procedure right when I have to install new MB BIOS so I can run some bulldozer in this MB


But I noob like me thinks that it should be reversible
