Do cards need to be clocked at the same speed to run in crossfire?
I believe it'll throttle the faster card down to the lower cards speed to answer your question.
^ Responants above with crossfire systems can check for themselves.
In my experience, setting different clock speeds does not prevent crossfire. Monitoring crossfired cards with different clock speeds using GPUz does not show any throttling of the faster card's clock speed. Cards carry out their individual role by Alternate Frame Rendering (AFR).
Not for years. You can set each clock (memory and core) separately.Hm.. I thought so too, that the faster card will be automatically throttled down to match the slower card.
i wrote a series on CrossFire scaling; PM me if you are interested in FrankenFire. It is very efficient. There is no "waiting" at all.Would be kinda interesting if it would effect framerates if they run out of sync....Seems like the faster card would be waiting for the slower card to catch up anyways.

SLI also allows for mixing and matching of clock speeds since last year.

i have been testing CrossFireX since 2900XT days. That is when mixing and matching of cards began. i ran a 2900Pro and a 2900XT at XT speeds; i could also set the clocks independently.Think you could just post it here? Seems like an item of general interest. From my understanding was that it would scale down to the lower clocked card, but I was told that when xfire first came out so maybe things have changed.
