Default Re: About Ground Loops & Oscillations - Stability

The answer is no. Do not think of a computer like you'd think of a power amp with vast differences in low level analog signal input versus high current ground returns from the load.

There are many many different hypothetical ground loops in a PC and it is not feasible to try to eliminate them, and no scientific backing in it being useful to do so for overclocking purposes.

On the other hand, if you wanted to apply a PC scenario to analog audio, it suggests the cleaner analog audio output is obtained by having a slight impedance from the ground plane to the audio card (instead of an integrated audio solution) and some LC filtration on that audio card.
