I'm sorry, but that's not how things work. You want an upgraded video card, you buy an upgraded video card. Why would you think you could get new hardware for free?

Well you could overclock it to squeeze out some extra performace. You can use precisionx or msi afterburn to do so, but make sure to read up on some how-to's first.
 
If you lucky like I was you ,ay be able to upgrade with a firmware upgrade

I upgrade firmware to unlock the extra video pipes and turn my 6950 into a 6970

Worked for me... but its not for the feint hearted... if you mess it up... you can brick your graphics card.

Cheers

There's surprisingly little performance to be had from flashing a 6950 to 6970. Free performance is always good, but fewer and fewer cards unlock these days since they started laser cutting the dies rather than BIOS locking them.
 


Yes - the change goes from 1408 pipes to 1536 (about 9% increase)
throughput of 160GB/s to 176Gb/s (10%)

I cant recall the cost difference between the 6950 and 6970... but I remember it being significant.... obviously enough that I didnt think it worth the extra ...
and then I found out I could do it for free :)

Cheers

Let me know if you figure it out. I need new tires on my car but don't want to pay for them. Maybe I can get them replaced for free using the same solution.

There's about an $80 difference between the 6950 and 6970 I believe. Benches I looked at showed around a 6%-8% increase in performance for the unlock, while an actual 6970 has around a 10%-15% lead. So you don't really get a 6970, but something that's around halfway between a 6950 and 6970.

But like I said, if your card unlocks it's nothing but a free upgrade, and well worth the effort. If you follow the instructions and only do it with cards that have a BIOS switch, then there's no danger.

Nothing to lose, 8% performance to gain.

Last year I flashed a gtx465 into a 470. It ran ok but was a little unstable the nvidia driver would crash once in a while. I ended up having to back the clocks down to the GTX465 speeds, but i still had the extra ram the faster ram pipline, and the extra shaders. Even then it would crash a few times a month.
 


Is that logical? my understanding was that even from manufaturer - the only difference was the BIOS lock... so why would it be different? sure your benches were "like for like" in all respects (execpt for the BIOS lock)?
Different manufaturers fiddle with the clock/mem type/speed/capacity so sure the benches were comparible?

Binning differences, though the discrepancy wasn't as big as I'd remembered. You get something like 98%-99% of the performance of a 6970 from an unlocked 6950.
