As title says. Card is a "GV-R695D5-2GD-B" model.
This card features a dual BIOS. I have flashed the first BIOS with a shader unlock, as was popular to do with the 2GB models of the 6950.
The card has been running stable and performing flawlessly for nearly 2 years with this BIOS mod.
This is NOT the 6950->6970 mod that increased clock speeds and increased voltage; that mod tended to brick 6950's as the vram got too hot under the new voltage settings. All the BIOS does is unlock the shader cores, from the stock 1408 of the 6950 into the full 1536 of the 6970, but clock speeds and voltage remain at 6950 speeds. Without any voltage modifications this card will pull 405KH/s with scrypt mining, given a bit of overclocking.
I will honestly say that I did GPU mining with it from mid-2011 to late-2012, but I can also honestly say that the temperature of the card never exceeded 65C and the fan was never above 75%. The memory clock was turned down to 400mhz and the rig itself was a well-ventilated fullsize tower case. The card runs absolutely flawless, and I have used compressed air on it to blow it relatively clean of dust. It has been sitting on a shelf for about 3 months, as the machine it was used in has been turned into a gaming/nvidia box.
The card was powered by an 80+ Bronze TX Series Corsair PSU, which was attached to an APC Battery Backup unit.
