i7-9700k Overclock NEED HELP!
I also adjusted the avx to -3, which might have caused the drop. However, hwinfo shows it falling to around 3.0 GHz from 4.9. Your voltage has dropped from 1.325 to .9 at times. You didn't mention your temps—this could be thermal throttling.
When your CPU isn't under stress, its speed changes naturally. During bench tests, it should maintain its maximum clock speed. Even in games, if the performance doesn’t demand high power, the CPU will slow down due to power-saving settings. A drop in speed during stress tests usually indicates overheating, so a better CPU cooler is necessary.
The VRM (voltage regulator module) manages voltage for the CPU, which requires precise and consistent regulation. High-end motherboards often feature stronger VRMs. For overclocking, you need a more robust phase VRM along with adequate heatsinks. Excessive voltage instability in the VRM can cause your PC to restart frequently. A stable VRM ensures consistent overclock performance. With the right components, you might achieve 5.3 clocks at the same voltage as a CPU that runs at 1.35V on a better motherboard.
I believe you're asking about the speed and voltage drop during stress testing. The motherboard might handle some overclocking, though it's unlikely to reach 5.3GHz. Your CPU's capabilities would also play a role in this.

You didn't mention your temperatures—this could be due to thermal throttling. My temps are generally around 60-65°C with a 360 cooler, so that doesn't seem like the main issue.
You can configure your CPU to always run at maximum speed and turn off lower clocks via Windows power settings, selecting maximum performance for your CPU. To achieve a stable 4.9GHz without throttling, ensure your motherboard is capable and the CPU cooler works properly.
Usually you don't notice the CPU frequency drop when it's under stress. I'd expect a restart would happen anyway. Have you used an monitoring utility? I haven't tried any other programs, but I watched some videos by Asus about overclocking the 9000s and they all mentioned using HWInfo.
