GPU Conf fig Question

[stieber382]

I recently purchased a new r9 280 to replace my old 7770. I was curious if i could install the 7770 in another pci slot and have it fold with out crossfireing it  with my new 280. I was also wondering if that would effect game performance when I'm not folding with the 280?

For AMD cards you need the same chipset to crossfire and the R9 280 and the 7770 aren't the same. It probably won't make a difference when not folding but it could if you run multiple monitors or something.

You can fold with the 7770 and not on the new card. In FAH, just delete the GPU slot that corresponds to the new card and leave the one for the 7770. You do not need crossfire for folding.

 

Impact on gaming, should be minor, folding, even just GPU folding, does use some memory and CPU, but if your system is well spec'ed, should be ok when gaming on the 280 and folding on the 7770.

 

Your only issue, is if the 7770 needs to upload or download a new WU while you are gaming, this could tie up some bandwidth on the PCI bridge lanes, but should only be momentary.

@Whaler_99 If I understand correctly, you can't use two different cards at once, I have a 270, and have just bought a 6870, and can't seem to get them to fold together

you should be able to just fine, heck i'm currently folding with a nvidia gpu and a amd gpu in the same system. They will however be folding separately on a wu each. They won't "cooperate" on a single wu. You might want to re install the client after adding a new gpu, if it's acting up on you and causing problems.

 

could you be more specific as to how they can't fold at the same time? what goes wrong? there has been a number of issues over the weekend.. maybe it was just bad timing and you clashed with those?

Sorry, I should have thought of reinstalling F@H, that fixed it I was thinking it was driver related  

 

Thanks for the help anyway

np, a reinstall is often in order after messing around and swapping hardware.
