Water cooled, overclocked to 6.2 GHz in single core test

Water cooled, overclocked to 6.2 GHz in single core test

of Oliver Jaeger
An forum member reported that he was able to overclock his yet to be officially released Core i9-13900KF to 6.2 GHz in the Cinebench R23 single core test. He scored 2352 points while keeping the CPU constantly below 76°C with AiO water cooling.

On October 20, the new 13th generation Intel processors will be launched. Customers can then purchase the first three i9-13900K, i7-13700K, and i5-13600K CPUs along with their KF variants in stores. However, a user on the OCN forums ( named “Coodie” already got a Core i9-13900KF, probably due to a mistake by a retailer who prematurely sold the CPU to another OCN member, from whom he time Coodie is said to have acquired the processor.

The Core i9-13900KF is Intel’s new 13th Gen Raptor Lake flagship with a total of 24 cores, of which 8 are P cores and 16 are E cores. The F suffix indicates no graphics unit integrated. However, this was irrelevant to Coodie, because he was already using Nvidia’s new Geforce RTX 4090 as the graphics card for his test setup. According to official information from Intel, a maximum clock speed of 5.8 GHz is possible with the Raptor flagship. The overclocker exceeded this value by 400 MHz and thus achieved a combined OC clock of 6.2 GHz with 2352 points in the Cinebench R23 single-core test.

Also used was a Corsair AiO water cooling system (iCUE H150I RGB Elite), which was able to keep operation consistently below 76°C, a Thermal Grizzly CPU contact frame, and 32GB DDR5-6000 memory. G.Skill GiByte. With 2,352 points in the single core test, the Core i9-13900KF is in the corresponding range Hwbot Ranking 13th.

Coodie used an Asus ROG Maximus Z690 Apex as a motherboard. In the multi-core test in Cinebench R23, the overclocker also scored 41,940 points at almost 6.2 GHz. Tomorrow the specialized press will publish the first in-depth and independent tests of the three new Raptor Lake CPUs, coinciding with the official launch.
