It's not an OC issue. It has also happened at only 3.2GHz and even stock OC speeds and is not the typical screen freeze but rather accompanied with a loud audio stuttering sound as I said.
It also could very well have to do with whether or not the MB itself tolerates more than one audio device being enabled. I've read for instance some ASUS MBs do not support multichannel PCM pass through. Which may be why I can never get HDMI Audio to be configurable as more than just stereo in the Windows sound panel when it actually DOES show up as plugged in and ready for use. I also noticed it's when I disable onboard audio and uninstall the Realtek onboard driver that it DOES show up as plugged in and ready for use.
