AMD Ryzen Threadripper, world's first 32-core consumer CPU, has been overclocked to 5.4 GHz. Threadripper 2990WX @ 5.4 GHz Alva Jonathan aka Lucky_N00b overclocked AMD's flagship HEDT CPU to staggering 5.4 GHz. Such frequency is achievable with liquid nitrogen and extremely low temperature (we are talking ~184C here). Alva used MSI's X399 MEG Creation with custom LN2 BIOS and 16GB of DDR memory clocked at 3.4 GHz and very tight timings. It is said that such frequencies turn Threadripper into an extremely power hungry chip. A 5.3 GHz frequency already requires more than 1000W.
