you could run into this problem.



Actually, a 6-pin plug can pull just as much power as an 8-pin plug ... as long as, you know ... the wires don't catch fire from the excessive power draw. And that's pretty unlikely, frankly. I doubt that just having 2x6pin connectors rather than a 6pin + 8pin is going to impact max OC-ability.

How would you damage the card, exactly? Are the unlocked shaders going to sneeze on the other components and infect them? Makes no sense.

The thread is about unlocking 6950s. The thread is getting way off-topic for my taste. There's about 50 other threads that have single to single card considerations.

If the 580 had 2 GB, I would give it up for Nvidia still, but come on... 2GB in x-fire for $600-$700 unlocked? That's a crazy good deal. And I think most enthusiasts (these are enthusiast cards) are going to overclock them anyway. Well done ATi.

No I'm not a fanboy. Look at the stats.

Okay, I'll explain this more directly: *If* AT ANY POINT, FOR ANY REASON your 6950 COMPLETELY DIES, and you have a 6970 bios on it, you will be in jeopardy of not being able to RMA it.

Does that make more sense now?

Did you look at the success rates? And you can just FLASH back?

No, because it has an unwritable BIOS backup, so if your 6950 "completely dies" it will not be because it was flashed it to a 6970.

I like how you fall back from "your card will explode if you turn it into a 6970" to "well if it dies for whatever reason you're still screwed."

AMD is not retarded and its vendors are not retarded. The blowback from the community would be huge if they encouraged use of a feature and then screwed their users.

yes i like benchmarks....yes i like ATI AND Nvidia (see sig rig)

but a benchmark is worthless in real world use...period, because i gurantee whatever systems they benchmarked in, are not the same as yours, thus you WILL NOT see the same performance

Yeah, they will. Maybe not consistently on every game at 30" resolution and above with very high levels of AA, but at 1920x1200 or below, they will totally compete with 6950/6970 when all cards are at their max OC's.

And when you consider the fact that people are finding 470's priced at $220, whereas the 6950 is still around $300 (and unlikely to go down, what with this whole 'unlocking' business), I daresay ... even if you were correct ... 25% faster is not especially impressive.

I'd to see someone w/6950's in Crossfire, unlocked, OC'd, taking their best shot ... beat this score by 25%:



Oh, and ... good luck with that

It's worth a try. Stock it would be fine though with 2 6-pins, right?

The point is that for consumers, doing anything to a stock card threatens ur warranty and could leave you cardless. But, we're talking about ENTHUSIASTS!!! If you are a consumer, buy what you need. If you are just about 95% of the people in this thread, SERIOUSLY CONSIDER 6950S IN CROSSFIRE! For $500 saved, I would happily accept small differences in performance between different set-ups compared to the test set-ups.
