If you don’t mind voiding your warranty on your brand spanking new Intel Core i9-11900K … and you’ve got the balls to up the voltage to a eye-popping 1.8573 volts! … Then you might be able to over clock the chip to a whopping 7GHz! Using liquid Nitrogen of course.
Taken from Videocardz … Intel Core i9-11900K, the flagship CPU of the Rocket Lake-S series, has been overclocked to over 7 GHz, according to the CPU-Z Validation website. Such a frequency was achieved with a massive voltage adjustment to over 1.873 volts. The overclocker signed as ‘Rog-Fisher’ was using ASUS ROG Maximus XIII Apex motherboard, a model designed for overclockers.

Meanwhile, an Indian YouTube channel PC Wale has a video showing the overclocking process of the same processor model but only to 6.5 GHz. This frequency was achieved at a slightly lower voltage of 1.678V voltage.
The overclockers from PC Wale received a custom XOC BIOS from SafeDisk, an overclocker from South Korea who works for ASUS. This version of BIOS unlocks the voltage to up to 2V. A frequency of 6.5 GHz by PC Wale was achieved with the ROG Maximus XIII Hero motherboard.
