[Help Request] 7950 to 7970 flashing problem.

post #1 of 6
Thread Starter 
Hello everbody,

Recently I was trying to flash my 7950 with 7970 bios. My card's Device ID is 1002 - 679A and the only 7970 bios that fits is from HIS. I flashed many different bios variations and all the flashes were successful but ATIwinflash keeps crashing when try to flash with this specific (HIS 7970 1002 - 679A) bios. I get the "ATIwinflash MCP stopped working" error all the time. I don't know what's wrong... It won't let me flash my card with this bios;

http://www.techpowerup.com/vgabios/126754/his-hd7970-3072-120816.html

But i can flash with other bios files no problem. (Tho they are not compatible)

What seems to be the problem here? Is this bios file defected/broken? What can I do?

Please HALP

Forgive me if I'm being stupid, but why would you want to flash a 7950 with a 7970 BIOS?

To unlock additional stream processors and gain additional performance.

Sorry to tell you. The 7950's are all laser cut, none of them unlocked as far as I recall. It's not the same thing as 6950-6970. All you will get is possibly higher stock clocks and a little voltage bump, you can achieve that by overclocking anyway.

What about the 7950s on the 7970 PCB?

AFAIK the 7950's on the 7970 PCB just had a bit better power delivery for better overclocking. I had a MSI Twin Frozr 3 7950 on a 7970 PCB that overclocked pretty well, I looked into unlocking a while back myself.
