Is flashing to 6970 seriously a no-no? - Page 2

This unproven rumor has been going on ever since the TechPowerUp article came out. There were cases on their forums of around 17 or so cards failing down the line a few months later. Of course, without a proper controlled experiment you can't tell if it was due to the 6970 bios flash or whether the card itself was just faulty.

No one really knows and no one really cares to find out.
It is more likely due to the 6970 flash.

I do not remember seeing anyone with problems straight off with the unlock shader bios in comparison with the 6970 flash.

THIS!!

People forget about the reason that the shaders they enable are labeled as "unstable", and overclocking them can cause major card failure.

Overclocking? Stick to 6950. Stock settings, yet got the guts? Flash.

not likely. you're now assuming ALL 6950's are just unstable 6970's. that isnt the case, as AMD has displayed a lot of what they do is just take a perfectly fine 6970 and software lock some shaders off of it for 6950's to meet demands.

just like what AMD did with the whole unlocking cores thing.

im at unlock shaders, 1.19v @976core.
i just put a random voltages and random core, been stable, but lazy to go higher.

You have to assume the worst scenario by default.

You get one with functioning shaders? Cool beans, unlock it. But by default, you should assume that they're defective.

you're right, but it's not like im the only one with shaders working fine. there're plenty, so assuming that the shaders are defective now is wrong- plus, reference 6950's arent as easy to get like they used to be.

I got mine with just unlocked shaders @ 900/1450 stock volts running like a champ.

I hate to say this, but it's not like overclocking them even makes that much of a difference in frames... Unlocking I can understand, then overclocking it to the stock 6970 speeds, sure, but why bother to go higher if it can run everything fine at 60 fps? there's no point...

That;s not the point. There's more to using a gpu than games. there're programs that take advantage of the processing powers of gpu's and then there are benchmarks.

Cant forget that, some people here just grab cards to oc, bench, and then resell.

Exactly.

If we take a look at the original TPU article, the success rate is enormously high:

Actually the unlocked shaders don't give as much of a performance boost as higher clocks:

Which is why it's best to not only unlock them but OC them as well.
