as i experience some heavy fluctuations in the VDD line of my EP-8RDA3+ Rev.1.1, i searched the web and found it to be *bad caps*...
After reading that, i even had to look up what "cap" meant and finally found this site.
The boardmember "Sticky" had the same problem:

Unfortunately, i cannot (yet) identify the bad caps by looking at them (no *bulged*, no electrolytic pouring out etc.)...
Hence i need to identify the capacitators...
