Any issues crossfiring a true 6970 with a 6950 flashed to 6970?

Will it run like it's a 6970 crossfire setup? Any issues with this idea? Anyone try it before?

A 6950 flashed to a 6970 is a 6970, so yes it'll work. It's the same GPU.

6970 can be crossfired with 6950 as well, without flashing.

yep. i had a spare 6950 doing nothing so i put it in my wife's computer with a 6970. works fantastic. i love AMD's multi-gpu features. you're not as constrained as nvidia

If you do this with two cards of different VRAM amounts, does it default to the size of the smaller card? IE if you combine a 6950 1GB with a 6970 2GB does it function as a 1GB or 2GB setup?

yeah. it'll take the memory of the lower card. unless they changed it recently that is.

It can only function as a 1GB setup. With AMD GPUs everything is as strong as the weakest link, the clocks will be the same as the lower clocked GPU as well.

Not with the clocks. Xfire does load balancing, I hear there are stability issues, but as far as I know only the vram is compromised when 2 non-identical cards are used together.

the cards don't run at lower clocks,whatever i set the clocks to that's what they run at

To my knowledge, yeah this should work fine. I've heard that you can crossfire different GPU's on the same architecture as well but haven't tried it. IE you should be able to crossfire a 6950 and a 6970, even without unlocked shaders. SLI can't do this of course.
