What just happened With Intel's Rocket Lake-S desktop processors coming out tomorrow (March 30th), enthusiasts are pushing the line's Core i9-11900K to its limits. While an overclocker was using liquid nitrogen to force the chip to 6.5 GHz, someone else managed to get 7 GHz.
According to the CPU-Z validation website (via VideoCardz), the flagship of the Rocket Lake-S CPU was clocked at 7,048 MHz. An overclocker named "ROG-Fisher" accomplished this feat by setting the voltage to 1.873 volts and using an ASUS ROG Maximus XIII Apex motherboard along with some exotic liquid nitrogen (LN2) cooling.
ROG-Fisher holds the top three overclocking records for the Core i9-11900K with a base frequency of 3.5 GHz on the CPU-Z validation side. Their second and third placed clocks reach 7,034 MHz and 6,898 MHz respectively.
These weren't the only tall overclocks recorded on the chip. The Indian YouTube channel PC Wale reached 6.5 GHz with the same processor. Again, LN2 was the preferred cooling solution, even though the voltage was less than 1.678 volts and the motherboard was a ROG Maximus XIII Hero.
The channel used a custom XOC BIOS from SafeDisk, an overclocker from South Korea who works for ASUS. It blocks the voltage at 2V.
You may recall that the Core i9-10900K hit a whopping 7.7 GHz shortly after it was released in May last year. We can therefore assume that the current top Core i9-11900K overclocks are defective after the official start of the processor. Hopefully it will beat the last generation record achieved with an Asus ROG Maximus XII Apex motherboard and a core voltage of 1.194.
If you're planning on buying a Core i9-11900K and overclocking the CPU to an inch of its lifespan, keep in mind that Intel discontinued the Performance Tuning Protection Plan (PTPP) service earlier this month. The program, which protected against the risk of damaging a CPU when overclocking, ended due to a general decline in demand. According to Intel, "customers are increasingly overclocking with confidence."
