[Tutorial] ATIWinFlash - How to flash the BIOS of your ATI Cards - Page 2

post #11 of 214
Sweet, i was wondering why my msi tf3 7950 was shipped in position 2.

Now i just need an unlocked bios because I'm stuck with no voltage control no matter what program i use.

Im also stuck at 1100mhz and no program will let me overclock further.

Anybody have an idea where i can get an unlocked bios that will allow me to possibly get up to 1200mhz with some minor voltage tweaking?

Was thinking about trying this on my new Saphire 7970 GHZ edition its the double 8 pin version and the voltage seems to be locked at 1.25.
Does any one know which bios to use that has unlocked voltage ?

I did the -mcl mod to Msi afterburner to get past the 1100mhz.

However, if i'm getting 1200+ on my card with the stock bios, is there any reason to try a different one?

What voltage do you need to run those clocks?

I think at 1.1 -1.150 is usually where I hit 1200/1700.

I just got my Sapphire Dual-x 7950 today to crossfire with my MSI TFIII 7950. They are both boost cards and the clocks were jumping when gaming which was affecting the performance so I decided to flash the BIOS's to non boost bios of the same cardS. I did the non-boost MSI 7950 and the non-boost Sapphire 7950. I followed this guide ( http://www.overclock.net/t/1353325/tutorial-atiwinflash-how-to-flash-the-bios-of-your-ati-cards ) SPOT ON. My MSI card is in the x16 lane (TOP) (so I figure that is card "0") and my Sapphire is in the 8x lane (BOTTOM) (so that should be card "1", right?) Both cards are set to BIOS 1. I went to flash the MSI (atiwinflash -f -p 0 MSINoBoost7950.rom) and it fails a quarter of the way through ("atiwinflash has encountered an error windows is searching for a solution"). Ok, that was wierd. So lets try the Sapphire. atiwinflash -f -p 0 SapphireNoBoost7950.rom. It finishes and asks me if I want to restart. I say yes. Restart is fine and I go into windows and it is saying that there is no AMD drivers installed or they arent working correctly. Directx 9 doesnt initialize correctly. Did I flash the Sapphire BIOS onto the MSI card or something? I open afterburner and none of my cards are recognized. I shutdown and flick the MSI BIOS switch to "2" and I blue screen trying to log into windows. I set them both to 2 and it logs in but still driver error, catalyst wont launch, nothing. I'm scared to even try to flash the original BIOS back because now I'm not sure if the MSI is really card "0" while the Sapphire is card "1".

PLEASE HELP I'M ABOUT TO FREAK OUT

You failed to flash the 1st BIOS.

Are you sure you took a compatible BIOS for this card? Anyway, since you have two BIOS, there is nothing to worry about. Follow these steps to flash BIOS #1 back to normal.

Lets say your borked your BIOS flashing and the BIOS #1 is now corrupted and you can't boot into windows using that BIOS

-Turn Off PC
-Put the swtich 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

Keep in mind that when you flash your BIOS, its like removing old cards and adding new ones. So you need to uninstall all drivers and install them again, its my preference.

Under Windows is my favorite method and do no harm at all to the graphic cards. I have used that method MANY times and I prefer it over the DOS method.

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
