There are some videos using the vf curve promising 6.0Ghz and more . In one of these as you can see at idle it reaches 6.0 (not all cores), however during the stress test it drops to 5.4/ 5.2. Its lower frequency even than the 13900k provides in all cores under stress in stock (at stress its 5.5Ghz all Pcores and 4.3 all Ecores).Its something to think about... I use almost the same adjustments suggested by one of these videos in order to reach 6Ghz, and in the end the difference for my suggestion of 5.6Ghz.
