Thanks!
I entered the commands and made sure it was on performance,
 but no luck. Same terrible noise.

I know it does help with some of the pops and clicks though.
Just not the digital noise.

I'll see how the new replacement MB works out. 
Hopefully it will remain stable. It worked fine in the shop...
