I had to uninstall Aida64 (1.60) and open a bug report with them. They suggest Intel raid drivers but I think its more likely to be general Sandybridge bugs. They offer a solution btw for the beta.
I have a P67 asrock e4 mobo and i5-2500k.
In games and during music play back there were stutters and pops. When I closed down Aida64 the sound glitches went away. I also noticed to freezing with Realtemp (its also discussed else where on this forum).
I am sure they'll fix.
Using paypal to upgrade license worked fine for me.
