Crossfire Mining?

[sterob]

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?

You'll get more hashes/second if they run un-crossfired.

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.

Lets find out.

Trying that now with my 7870s.

I agree. Crossfire just reduces the hashes per second.

After a quick AVP benchmark run, I disabled crossfire and had no issues running scrypt on both gpus, without having to reboot. Then I stopped mining with GPU0 and ran AVP while GPU1 continued to mine.

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.

Yes this is typically what I do when editing hi res raw images at the same time 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.

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