Update: Not sure first card match applied custom fan curve at all. Notice it runs 100% at 70-72C, even thou fan curve is set to hit 100% at 90C. 😕
Edit:
Version 2.7.5.0
Seem easier to adjust the custom fan curve, more lightweight with monitor on
and GPU2 show correct ID on monitor gpu selection 🙂
With GPU Tweak on turning CrossfireX off within Catalyst Control Center and >ULPS off< results in Blackscreen.
Screen goes black again if restarting and logging on.
With GPU Tweak on turning CrossfireX off within Catalyst Control Center and >ULPS on< seem to give different odd results.
First time GPU Tweak turned itself off.
Second time fans on GPU1 stopped spinning and GPU2 started instead... not sure I want to test that a 3rd time :S
Solved above by holding "shift" and clicking "restart" at login screen (win 8.1),
then choose Troubleshoot - Advanced Options - Startup Options - Restart
> Safemode Mode to delete GPU Tweak folder and restart again
> Run Installer to uninstall rest (Uninstall thru Control panel works too I guess)
> CCleaner (Run Cleaner and Registry Cleaner)
Edit2:
Custom Fan Curve is still just added to GPU1 even with ULPS off 😆
Kinda helps OC having ULPS off, so all options are available for all cards not just GPU1. 😛
Edit3:
Installing AMD Catalyst driver (14.11.2 Beta) and then installing GPU Tweak 2.7.5.0 resulted in blackscreen.
Same driver is fine with GPU Tweak 2.7.1.8, unless I try to turn off CrossfireX 😛
Noticed sometimes when turning CrossfireX off with ULPS on, values within GPU Tweak seem to drop slightly.
Id guess same happen with ULPS off, but it leads to blackscreen so can´t see values after change.
Could it be that voltage to the GPU gets to low at that point, cause GPU Tweak bugs out and change GPU(s) to lower values?
