I am trying to use 2 AMD cards at the same time and I'm having some hiccups, so i'd be grateful for any help.
On my PC, Abit P5Q pro motherboard, I have a 5870 that I want to use for mining all the time and a 4870 that I want to use for the desktop and games. The 5870 device 0 in the top PCIe slot and the 4870 is device 1 in the lower PCIe slot. At the moment, the only way I can make it do what I want is as follows:
Crossfire the 2 cards. Boot up with monitor attached to 5870 Use MSI Afterburner, set 5870 as master and adjust settings for mining Run miner Disconnect monitor from 5870 and reconnect to 4870 Run games
If I boot up connected to the 4870 or swap the monitor over to the 4870, MSI Afterburner won't let me change any settings on the 5870, even if 5870 is set as the master card. If I now change the master card in Afterburner to the 4870, I can adjust this cards settings.
Is there a simpler way I can tell the PC to mine with the 5870 and play games with the 4870? I thought I wouldn't need to Crossfire, but if I don't, the card that isn't connected to the monitor do anything.
/edit Should have said that I'm running Windows 7, 64 bit, and AMD 11.3 Catalyst.
