Highly doubt the VRAM is to blame, GDDR5 used in 6970s is H5GQ2H24MFR-R0C rated at 1.6V vs 6950 H5GQ2H24MFR-T2C rated at 1.5V
.1V is nothing for GDDR5.

Yeah a small increase in GDDR5 is not going to do much to HD 6950. Also just moded HD 6950 is not supported by MSI SB. I also have no problem with mine. I am 100% that those people that got the problem ran the card with stock fan profile which is fail. I tried and i was getting ~ 78C in SC2 which does not push the card much. Put in Custom fan profile and now it does not break 65C. If memory is over-volted and overclock and running hot its going to dye.

They were referring to the ram timing not the voltage. There was also a comparison b/w both bios and what make them difference from each other as well as PCB specification and yatyatiya... If you google there are several reliable resource that talks about the card. Nonetheless the odds of flashing the card w/o damaging it are high, at least for now. They simply stated the best way to flash your 6950 is to unlock the shader w/ your original bios.

OP only have good intention to warn people of the so call "6950 flash to 6970 risk free" due to dual bios. Which some have learn the hard way and had to RMA their $300 card.

I also flash my 6950 to 6970 Sapphire bios the same day I got it. Everything ran smooth as silk and all benchmark ran great except for 1. I had massive artifact on 1 test only and decided to flash the 6950 to unlock shader only. Test it again and no more artifact on any benchmark/stress test. There are also a few 6950 owner who experience the same thing...

OP + rep for warning, thx.

Is there a significant performance difference between a stock 6950 and a stock 6970? Because the 6950 just looks more alluring to me. If I had the money, I'd go back to ATI in a heartbeat.

Jesus the grammar in this thread is apalling.

On topic: The 6950 GPU and memory are lower binned parts when compared to the 6970, therefore it is common sense that the unlock won't allways work.

However the 6950 GPU and memory are made using exactly the same fabrication process and the reference card even uses the same PCB, the voltages are not to blame here. It is more than likley the temperatures the card is reaching when operating in an unlocked state, which is porbably the reason the GPU on a 6950 was binned for a 6950 and not a 6970.

Timings do not damage the memory, its the same as changing timings on your RAM, it either works or BSOD. You got artifacts because you have memory that is unable to handle those timings.
That is the dumbest claim, ever. Stop making up rumors.

It has to do with heat IMO...
People aren't aware of what they're 6950 > 6970 temps are getting to... I was playing Crysis warhead for about 5 minutes on max settings and I peeked at 97*c (~25*c room temp) luckily my NZXT Sentry 2 went off... I then just made a fan profile in MSI Afterburner and they now stay down to about ~65*c... noisy though :/

As ZealotKi11er said, if it's been overclocked and overvolted and is getting this crazy temperatures, it will die.
maybe someone should send a message to Wizard@techpowerup so he can emphasize on this, even if it isn't the course of the cards deaths.
