Indeed. It's a curiosity question with regard to threadripper and the relationship between package power and power allocated to the CPU cores themselves when operating at the default TDP limits.
The Anandtech review appears to show a potential performance issue caused by running at higher RAM voltages when not overclocked. And the poster on this board (ub4ty) seems to suggest that performance regression at higher RAM voltages/speeds was commonly found in reviews when tasks were not heavily bound by memory bandwidth -- that was news to me! I could not find such reviews.
So, the question is really whether there is any real evidence for a performance tradeoff at stock CPU settings when using higher RAM frequencies.
[For Reference: I was more likely to see examples like this (see second graph), where virtually all tests show higher performance with higher memory speed.

That said, it is possible that these reviewers are running their RAM modules at 1.35V (standard voltage for higher clocked kits) at both 2400 and 3200 MHz, meaning the disadvantage of higher voltages is uniform. They do not specify.]
