Recently bought an XFX 6850 XXX Edition basically it runs clocks @800/1050. I installed 11.6 and cannot modify voltage control in Trixx latest beta and MSI Afterburner latest beta (after cfg) modification. I'm not sure if the overclocking software has to be updated to 11.6 Catalyst changes or is the XFX card voltage locked? I did already search seems other people can adjust voltages on the XFX @775/1000 model, and or black edition. Will I need to flash a 3rd party bios or the overclocking software has no support yet?
