--- Comment #72 from MasterCATZ (mastercatz@hotmail.com) --- finally this summer the R9 290 GPU's will be manageable
seems to be working , now I just have to find the old settings I changed when trying to run it at higher rpm , @ 60deg and its doing 80%+ RPM possibly it is now following my BIOS settings from when I was trying to force higher RPM when it kept trying to run under 20%
my manual settings seem to get overwritten a second after setting them but at least I am not being locked out like before
now if someone could solve the issue when it uses more power when running multiple displays ( exactly the same monitors res / hz ) I can run the card single display under 10 watts plug in another display and its over 50 watts idle
