It took liquid nitrogen to do, but an experienced overclocker took the 4.3GHz Ryzen 7 2700X all the way to 5.884GHz and and the 4.2GHz Ryzen 5 2600X to 5.882GHz.  If that doesn't impress you, then how about the fact that all cores were running at that speed, and not just one core active?  You will not see such high frequencies when using less esoteric cooling solutions however this indicates some serious overclocking potential for the new Ryzens in general.  Check out the proof by following The Inquirer's links here.

"AMD'S RYZEN 2 processors are set to be proper powerhouses as the Ryzen 7 2700X and Ryzen 5 2600X chips have been overclocked beyond a preposterously nippy 5.8GHz."
