They carry an Intel Core i7 7740K processor of Kaby Lake-X architecture up to a stable frequency of 7.5GHz through extreme overclocking, cooled in this case with liquid helium.

During the past Computex 2017 we attended the officialization of the Intel Basins Falls processors, which should reach the market by the end of this month, at least a part, since two Kaby Lake-X and two Skylake-X will arrive, until i9 7900X, the rest of the processors will arrive gradually. During the Taipei event we already saw how one of Intel's processors was subjected to extreme overclocking by several professionals in the field and now it has been given again, but in this case looking only for a frequency record.

This time the Intel Core i7 7740K processor, from the Kaby Lake-X family, has been used. The Australian professional team TeamAU, together with some members of the Gigabyte OC Lab have brought this processor to a stable frequency of 7.5GHz. This has been possible by deactivating two of the four cores, raising the multiplier to x75 and providing a frequency of 100MHz, which has resulted in the interesting figure of 7.5GHz. It should be noted that these two cores had a working voltage of 1.096V.

For this practice, a Gigabyte X299 SOC Champion motherboard has been used and liquid helium has also been used, not liquid nitrogen, as is usual in extreme overclocking, which seems to have allowed a finer and more stable overclocking. This result has been validated by the CPU-Z Validator. It should be noted that this type of operation is usually carried out to see the limits of the processor and synthetic benchmarks are not used in these cases because it is usually quite difficult to pass them. It is one thing to see the technical limits of the processor and see how far it can go without problems and another thing is the extreme overclocking for synthetic benchmarks, where the frequencies are lower and what is sought is to know the maximum performance of the processor under certain conditions.
