Windows 7: Radeon HD 6950 2GB Flash Mod

Radeon HD 6950 2GB Flash Mod

So, I've got the first interface design Radeon HD 6950, and I can flash it to a 6970. But, apparently if you don't do it the right way, after a week or so you'll get artifacts. This is caused by the RAM which in the 6970 is set to a different voltage. I'm using an XFX card, which according to the graphs on TechPowerUp, has a high success rate.
I just wanted to know: Would it matter if I used the .zip or followed the instructions?
Also, it says after you flash it and set the PowerTune to +20%, your card will consume 252W and reach 92C. My card has only ever reached 78C so far. Is 92C OK and is 252W OK considering I have a 650W?

Hey there, I have a MSI R6950 and I unlocked the card to the use the extra shaders but not the full 6970 bios.

Unlocking Radeon HD 6950 2GB

her is the link i used, i can still overclock my card with just unlocking the bios and not using the full 6970 on, with the 6970 on I can no longer overclock the card and keep it stable. with just opening the shader's I can overclock and run fine, I have tested this out myself and it works great.
Let me know what you decide on doing.

don't forget if you do flash it and it goes wrong you will not get a replacment card or get it fixed on warranty you will lose the money you spent.

there is a very good reason they aren't 6970's just be aware of that.

I'm actually doing research now on whether to flash my 6950 to a 70 or not. When I bought it months ago I that was the plan, but once I got it and used it as is there wasn't any need to flash it.

Now the flash would be purely for the sake of saying I did it, though he extra umph wouldn't hurt either

We'll see.

I knew well before i bought it what i could do and what they wouldn't take back. But with the dual bois on the card it makes it very nice to have the extra shaders and to have it overclocked easily. I have two setting on my afterburner software. Desktop and game mode, desktop keep everything to factory speeds and game mode over clocks it to max I keep an on screen display of the heat on the card so if it gets too hot i can stop the overclock.

Ok i just wanted you to be sure what you were doing is all

i'm not trying to put you off doing it or anything but several have been bricked from flashing it so dual bios or not it killed the card.

flashing is not like overclocking at all, what your doing will open up the gpu to unstable voltages. They failed that test and became the 6950's we see on the market as there is nothing wrong with them at slightly lower voltages.

the 6970 has much stricter voltages and the pass rate to get that isn't easy for the manufacterer to achieve.

Like any overclocking/tweaking of hardware there's always the risk of bricking something. This we know, this we understand, yet we proudly take the risk anyway. Why..... because we're overclockers/tweakers – we do it because we love it

indeed i'm an avid supporter of overclocking to maximise hardware, but even i draw a line at flashing a bios to make a gpu think it's something it wasn't cut out to be.

Well this is more safe than most considering the card has a dual BIOS. But you have a valid point.

That's exactly my story! I bought it and planned to flash it, and haven't needed to!
I heard it consumes more power though, and you need to put the power control in CCC to +20.
I may flash it soon, just right now I need to upgrade my CPU and monitor
