What just happened? It’s only been a few days since the Core i9-13900K was released, but Swedish overclocker Elmor has already used it to break the record for the highest clock speed ever achieved (and validated): an incredible 8812.85MHz .
According to HWBot, the record last changed hands eight years ago when an AMD FX-8370 was pushed to 8722 MHz. CPU-Z says the record has long been held by an AMD FX-8350 clocked at 8794MHz, but both sites agree that the 13900K was the first CPU to pass 8.8GHz and is the current champion .
It’s also the first Intel CPU to beat AMD’s recent memory record – at least a decade.

At default settings, the 13900K clocks in at 5.8 GHz on as many P-cores as the program can use, before cooling down to 5.0-5.5 GHz as it warms up. It could probably support those higher clocks if it could stay cool, but even big AIOs seem to struggle to contain their ~300W package. In any case, it is a prime candidate for home heating and overclocking with exotic cooling.
Elmor used LN2 (Liquid Nitrogen) to cool the CPU during the record attempt at a pre-release overclocking event held by Asus. They poured the LN2 into their own homegrown ElmorLabs volcano pot, which looks like it’s using an unusual amount of copper, judging by their photo.
Rounding out their system was an Asus Z790 ROG Maximus Apex motherboard and 32 GB DDR5-4800. Their photo shows a Lepa G1600 power supply on the side. And of course they stuck with Windows 7.
As for the CPU configuration, the overclock was based on a bus clock of 100.15 MHz and an x88.0 multiplier was applied to the sixth P-core. The rest of the P cores remained at the 3 GHz base clock and the 16 E cores were disabled. Elmor didn’t share the voltages or temperatures, but perhaps a future record attempt shared on YouTube will have those details.
Even more impressive than just the record is that it was achieved with a technical monster. It’s likely that the clock speed record will go up as other extreme overclockers get their hands on the discarded 13900K production samples that can be pushed a little further.
