2900Xt Crossfire Question

post #1 of 7
Thread Starter 
I just bought a 2900XT to run in Crossfire with the card I currently have. Mind you this is on a Gigabyte board with Crossfire, not the board in my sig.

My concern is two part. First is that my current card started life as a 2900Pro and I flashed it to XT. Would would that cause any problem.

And second, do both cards need to be clocked the same. I modified the bios in my current card adjusting the clock speed. So if I put the second card in running at stock XT speeds will that be an issue as well?

It might probably won't work with the different speeds, but you can try, crossfireX is pretty cool , the pro to XT won't affect anything.

The flash isn't a big deal but (IMHO) you need to baseline both cards at the same speed. Good luck and enjoy (these rock in crossfire).

QFT. 2900 pro = 2900 XT, end of story.

It doesn't really matter if you have the cards at the same core speeds, it's just a good rule of thumb to have them match.
