In anticipation of the release of Intel Comet Lake-S processors, ASUS gathered several successful extreme overclocking enthusiasts at its headquarters, giving them the opportunity to experiment with the new Intel processors. As a result, this made it possible to set a very high maximum frequency bar for the flagship Core i9-10900K at the time of release.
Enthusiasts began their acquaintance with the new platform with “simple” liquid nitrogen cooling. Of course, it was not possible to immediately achieve stable operation of the system, but through trial and error, the experimenters managed to achieve some significant successes. The results of these overclocking experiments are not specified, but in the HWBot rating there is a record that the Intel Core i9-10900K processor reached a frequency of 7400 MHz using liquid nitrogen. The author of this record is the Belgian enthusiast Massman, who was a member of the team assembled by ASUS.
After liquid nitrogen, overclockers switched to experiments using a colder substance - liquid helium. Its boiling point approaches absolute zero and is -269 °C, while nitrogen boils “only” at -195,8 °C. Not surprisingly, liquid helium can achieve much lower temperatures for cooled chips, but its use is complicated by its high cost and rapid evaporation. That is why enthusiasts had to worry about a continuous supply of helium into the copper glass on the processor.
As a result, a Swedish enthusiast with the pseudonym elmor managed to achieve a very impressive frequency of 9 MHz on the Core i10900-7707,62K, and the chip retained the activity of all ten cores and Hyper-Threading technology. Note that this is a very high bar, especially considering that for the previous Core i9-9900K the overclocking record is currently 7612,19 MHz, and for the Core i9-9900KS it is only 7478,02 MHz.
ASUS provided the experimenters with their own motherboards, specifically tailored for extreme overclocking - the new ASUS ROG Maximus XII Apex on the Intel Z490 chipset. Also, the test system used only one G.Skill Trident Z RGB RAM module.
