Speed settings aren't being applied correctly to the I5-7600k processor.
Your PC runs a 7600k processor and you've been trying mild overclocks for a month. You're seeing stable performance at 4GHz, which is better than the stock 3.8. However, your BIOS limits you to a multiplier of 42, even though you're confident it should be higher. Task Manager and HWMonitor both display the CPU clock at 4GHz instead of the expected 4.2GHz. As a beginner in overclocking, any guidance would be really helpful.
Under normal conditions, the top boost frequency for the 7600K with four cores reaches 40 MHz, while one core allows up to 42 MHz. Without a Z-series motherboard, these values will be your upper bounds. Ensure the Core C states are activated in the BIOS to benefit from Intel Turbo Boost.
