Thanks omniphonix! I’ll add these to my arsenal of gathered tweaks during my quest to the ultimately optimized system. I’m still not fully satisfied with the audio performance of my setup. My system for instance needs hyperthreading to be disabled otherwise the performance meter will hit red very soon. I have a suspicion that this mainboard is not the most suitable one for this kind of thing. It’s rock solid but not very impressive when it comes to real time audio processing. Maybe time to give up and go look for another one?
