Yeah I know, the LN2 overclocks are getting a little out of fashion. But hey, this is pre-launch stuff that gets out and at least worth a mention. An overclocker called TSAIK has had access to  Ryzen 5 2600X and the Ryzen 7 2700X, he is liquid Nitrogen to cool them and reaches 5.8 GHz

As you guys no know, Ryzen 5 2600X processor has a base clock of 3.6GHz and a max clock of 4.2GHz from the factory. TSAIK tweaked the chip to a max overclock of 5883MHz, that is on all six cores. The motherboard used here was an MSI X470 GAMING PLUS motherboard running a staggering 1.768 volts on the processor.

The Ryzen 7 2700X reached 5884MHz on all 8 cores. This processor has a base clock of 3.7GHz and a turbo clock of 4.3GHz, here again, an MSI X470 GAMING M7 AC motherboard was used with CPU Vcore set at 1.76 volts.
