The engineering sample Core i7-7740X under liquid nitrogen overclock to 7.2 GHz, and liquid helium raises the bar by another 300 MHz. However, all these modes of operation are far from the daily routine, and therefore the actual overclocking statistics, brought by Intel company , are brought closer to the hopes and aspirations of simple overclockers, which are limited to liquid cooling systems.
According to Intel, a sample of hundreds of engineering samples of the Core i7-7740X allows to speak about the ability of good instances of this processor to overclock to 5.0 GHz at a voltage of 1.205 V. "Bad" instances are overclocked to the same frequency already at a voltage of 1.341 V. Apparently, The use of liquid cooling, since it is recommended by Intel, even for the nominal operating modes of these processors.
By the way, the green curve on the graph shows the results of overclocking using the air cooling system. As you can see, up to 5.1 GHz, the most successful instances of the Core i7-7740X are able to get and without liquid cooling. Related Products :
