Default Happy Holidays from AMD - Many Radeon HD 6950 Reportedly Unlock to HD 6970

Video cards originally meant to perform in their $300 price bracket have been successfully unlocked to perform well above expectations. That's right, owners of new AMD Radeon HD 6950 cards are able to re-flash the BIOS on their cards with a 6970 BIOS to reclaim SP and clocks that have been artificially withheld from them. The intrepid crew over at... [ Read full article ]

ooooh, I would not want to be a 6970 owner right now.
But - it's not really news that you can overclock a lower end card to a higher end performance anyways - because that's all they are doing, but from the BIOS level.
The 6970 could still overclock higher than a 6950 though, right!?

Some TPU users are damaging the ram with the 6970 bios, they are different hynix chips with different operating speeds and voltage tolerances (5gbs 1.5v, 6gbs 1.6v). That doesn't mean everyone will have the problem, but you have people that flash it to a 6970 stock, then overclock it further on top of that and wonder why it's now artifacting even when returning to stock 6950 bios.

The cards are not 100% the same, and the chips used are binned as such for specific reasons. More power to you if it works, just don't be one of the idiots that thinks because there is a bios switch that any trouble with the card means RMA time after clearly damaging the card themselves. At least things aren't as brazen here as the Linus video saying this is entirely risk free, it is not risk free at all.

And for the person asking, the 6970 has more headroom for OC then a flashed 6950>6970, the 8pin primary also helps with that.

Of course they post the bios mod the very day after I bought a 6970. Am I mad? Me? No. Never. Little bit.

Not going to return the card. I will however watercool that 6970 and see how far it goes.

Personally, I am absolutely sure that AMD knew what they were doing when they allowed this to happen. Someone may have even tipped off the XS community about it... it will probably piss off a few 6970 owners, but now anyone who cares about this stuff will buy a 6950 and the rest won't even know the difference. It's certainly a marketing decision... I guess we'll see if it keeps them competitive in the graphics market, right?

It's not just overclocking. You're unlocking two additional SIMDs, which gives you 128 more stream processors and 8 more texture units. As well, you're also getting a higher VID, so really you're also probably getting the same overclocking headroom as a 6970. However, this is all theoretical, and if the 6950 you got happened to be a poor performing Cayman that got binned low, or if parts are actually damaged or deficient, it won't work very well, if at all. So, it's still really luck of the draw; with a 6970, you know the chip can do the rated speeds, and with a 6950 you don't know. It should, but you might have one that won't.

Also, the 6970 doesn't come with 1 GB memory, so I wouldn't push the mhz on the memory if you do this to a a 1 GB 6950. As others have mentioned, some of them use cheaper RAM...
