I have multiple systems running windows 7 x64 with ati 11.4 drivers..
But my newest setup, is my main rig, which i use for gaming and such, i have a 5770 and a 5850 in it..
The 5770 is all i need when i play games, so i would just make it mine when i was at the computer, not doing anything else than surfing, but since i have put in the extra 5850..
I cant stop it, when its running, everythings fine, when i stop the mining on either of the cards, the system freezes, if i run just one of the cards its working just fine.
I have tried with guiminer and phoenix, the same problem, im about to test it with phoenix and phatk kernel, but i dont think it will change anything?
Someone who can point me to a solution to this? would like to use both cards when im not gaming, and when i am playing games, just use the 5850 for mining, so that one ís actually dedicated for mining..
