Check if the overclock of I7 8700k at 4.7GHZ and 1.185 is reliable.
Hello, I successfully overclocked my i7 8700K to 4.7ghz across the six cores with a Vcore voltage of 1.185. The stress test using Intel Extreme Tuning Utility lasted an hour, and the maximum temperatures stayed at 66°C. Do you think there’s still room for improvement? Is this overclock stable?
Here’s a summary of my build:

Newer updates to Prime95 often rely on the AVX instruction set, which can significantly increase CPU workload and temperatures. With adequate cooling, this could be manageable. Certain motherboards offer settings that reduce clock speeds when AVX is active. However, the general advice remains to use Prime95 version 26.6 since it avoids AVX instructions.
Prime 95 is the recommended software, keep an eye on the temperature and shut it down if needed.
