Hello. Im new and have just learned of the 6950 to 6970 mod. Im having issues getting it to install. First here are my specs- fx 8 core 8150 cpu. 2 radeon xfx hd 6950s crossfired. 2bg series. 16 gbs of sniper series ram. win 7 65bit. My card does not appear to have the 2nd bios but I was told I can steal do the mod. These are the steps I fallowed. http://www.techpowerup.com/articles/overclocking/159 I downloaded the ATIWINFLASH progam and unziped to desktop. Iv try to run the ATIWINFLASH.exe from the desk and all works fine until ((((Load the HD 6970 BIOS into Winflash by clicking Load Image, followed by Program. Let the flashing process complete and reboot your system.))))) When I click program I get a erreor saying Mismatched ID. So then I tried loading threw the CMD. I went to start - clicked run (Tab says This task will be created with admin privileges) I typed in cmd and click ok. CMD box comes up. I typed cd %USERPROFILE%desktop>ATIWINFLASH.exe Then I typed ATIWINFLASH -unlockrom 0 (I get a error saying USER\REGULATOR\ATIWINFLASH.EXE IS NOT A VALID WIN32 APPLICATION Just for the fun I typed - Then I typed ATIWINFLASH -f -p 0 unlock.bin and got the same error. Iv tried every trick I could think of and steal get the same thing. Below are notes on wear I had issues.... - Unpack the Winflash download onto your desktop in a folder called "winflash" - Save the 6970 BIOS in your Winflash folder and name it unlock.bin - Click Start Button - Type "cmd" - Right click the entry and select "Run as Administrator" - Black command prompt windows opens - Type "cd %USERPROFILE%\desktop\winflash" (If I dont type just like this (((cd %USERPROFILE%desktop>ATIWinflash.exe)))) THE same way its saved on the desktop cmd says - The system cannot find the path specified - So I typed it how i have it saved to desktop and then it seemed to work until I typed the next part.)))) - Type "atiwinflash -unlockrom 0" <-- the 0 means first adapter, if you have multiple cards, physically uninstall all but the one you want to flash (This is when i get the error saying USER\REGULATOR\ATIWINFLASH.EXE IS NOT A VALID WIN32 APPLICATION - Type "atiwinflash -f -p 0 unlock.bin" - It should complete the flashing process with a message saying something with "verified". Some one please help me. If some one doesnt help me - Ill have to go out and by two 7950s and on my way home - ill have to stop by the cort house and get my divorce papers - bc my wife will divorce me and ill have to go live under a bring bc she got the -house - kids - cars -and the dog.
