Have 2 powercolor pcs+ 290x in crossfire. Has been using the msi afterburner for over clocking. Decided to try using the CCC overdrive to do the over clocking. But I realise the option to set target temperature is missing. Uninstall and reinstall many time including a windows 7 reinstall. Nothing seems to help. Anyone had any idea what is happening? Thanks in advance
