6950 to 6970 flash thread

[twistedneck]

Did you flash the 6970 BIOS? If so then maybe the card can't handle the 880 core, maybe even memory.

There's a 6950 asus bios floating about which unlocks shaders etc but clocks stay 6950.

Yes, i flashed multiple bio files including Sapphire and the stock AMD 6970 bios they all behave in a similar manner. It boots fine but when i try any 3d app like ccc or msi, even gpu-z it just freezes the screen with some artifacts and then if i'm lucky the driver will recover and give a message about how it restarted, then if i try to do anything again the cycle repeats.

I have confirmed the card runs great when flashed back to the msi 6950 stock bios.

So, do i have the "golden shower" sample?

Most probably yeah. Download the 3.0.2 beta of trixx here:

That way you can go below CCC limits, to see if it's stable at 6950 clocks with the unlocked shaders.

You were correct all along, the modded 6950 bios was the trick. runs flawless now - so far up to 860 core and 1325 memory on stock msi 6950 voltage. Must have been some other setting in the 6970 bios that locked it - like mem or clocks too high, voltage too high, etc.. ideas?

Again, thanks Oztopher!

Here is the link i used for the 6950 mod bios

Tried it again and same results.... it stutters and frames drop in benchmarks.

Cobra does it work fine w/o the flashing when you use stock bios? I know your pain i dont think its the card its got to be one of the bios combinations that could make it work correctly although there is a very small chance its just a really low bin board, mine is also low bin but it at least unlocks ok.

Here is a link to the bios files i used including the modded msi 6950, stock msi 6950, sapphire 6970, and amd 6970.

Each individual card runs fine with the modded 6950 bios with smartdoc. It is the massive stutter it has when I do crossfire.
