Some have problems and many argue this is bad because the 6950 uses a lesser speed/quality memory that cannot hold up over time when put under the voltage/timings/speed of the 6970 bios.
2. Modify your 6950 bios, or flash a modified 6950 bios where everything in the bios is stock 6950 EXCEPT for unlocking the extra shaders. This is the safest because you retain 6950 voltages, mem timings, speeds, etc.
Hi, I modded my 6950 bios to unlock shaders but had to flash to a saphire 6970 bios as my afterburner was showing a max of 840 core.
