Title: Crossfire Mining? Post by: sterob on October 31, 2013, 02:02:15 AM I am a softcore part time miner, so I am thinking to buy another GPU for both game and mining.
Is it possible to crossfire them to play offline game, then un-crossfire without having to unplug the xfire bridge and restart. So i can use 1 card for playing MMORPG while the other can keep mining? I remember people mention that for crossfire both card will run on the same clock speed. After un-crossfire can i run them on different clock/mem speed and voltage? Title: Re: Crossfire Mining?

I think there's an option in Catalyst Control Center somewhere to disable Xfire profiles for certain things, try disabling it for your mining program. Title: Re: Crossfire Mining? Post by: Hippie Tech on November 01, 2013, 02:08:31 AM Lets find out. :)
Trying that now with my 7870s. Title: Re: Crossfire Mining? Post by: balanghai on November 01, 2013, 02:11:32 AM I agree. Crossfire just reduces the hashes per second.

That last part isn't new to me as I have flipped between the gamer/htpc/miner mode many times before. You'll be ok as long as GPU0/ the main display, is run at stock speeds. I'm using the 13.9 drivers with the 13.5 CAP1 app profiles, btw. :) gl xD Title: Re: Crossfire Mining?

I set the GPU running the monitor to not be included in the miner. It also gives me a cooler temperature running only 1 GPU in my dual GPU card. Title: Re: Crossfire Mining?

You can always de-active the first GPU just for gaming and the real continue to do the mining work.... |
