Questions regarding 6970+6950 Crossfire

post #1 of 10
Thread Starter 
Is it true that when you CF a 6970 and a 6950 together the 6970 is underclocked to the speed of a 6950?

What he said. However some 6950's can be unlocked to a 6970. Also the difference between 6950's and 6970's in crossfire is marginal at best.

I used the word 'theory' very specifically. I see better results running my 6950 clocked 60-80hz lower than the 6990, than i do clocking them the same. Use that info as you will.

The gpus are free to run at whatever frequency you want them to run at. This whole locking business is not true on current gen cards.

There are a lot of misinformations about AMD cards.

AMD cards can work at its own respective core/memory clocks and votages in cross/tri/quad-fire configuration. They don't have to be sync'ed.

We are not talking about Nvidia cards.

I understand we can clock them differently, but i was perhaps under the false impression that they were throttled somehow to put the cards on semi-par performance. I guess not. Good to know.
