Yeah, I've already seen that. I've removed the old card before writing the first post, and later I've removed Catalyst with DDU and did a 'clean' install of the new Radeon drivers.
Disable CrossFire, don't use Remote Desktop Connection.
I haven't been using either. There's only one card installed as of now, and the miner gives no temperature info at all.
There is no monitor on my system but when i add a monitor to GPU0 and start the miner it now sync the settings to all cards.
Is this a bug?
