The clock speeds are fluctuating due to how much load is being applied to the cpu, I do see they hit 5.1GHz as the maximums are showing. To get the cores to run at a constant overclock, set the windows power plan to high performance.
When using one monitor with a dedicated gpu, I let the iGPU disabled.
It seems your memory is unstable, what can help is raising these voltages:
CPU System Agent voltage: 1.25v - 1.30v
CPU VCCIO voltage: 1.25v - 1.30v
I have a delidded 7700k that can run at 5.2GHz with 1.44v.
See how it goes after raising those voltages.
Instead of using a per core overclock, try "Sync all Cores".

Well, cpu degredation is possible when overclocking and how fast it starts really depends on temperature and as you said how much voltage and quality of the cpu.
Intel recommends a maximum of no more than 1.52v for the 7700k so up to 1.45v I feel safe with, I ran it there 24/7 for five years until I recently upgraded.
Here is a video of my 7700k playing watchdogs 2 at 5.3GHz with 1.52v.

Yes voltages are correct, I also use HWinfo.
I used Thermal Grizzly Conductonaut between the die and IHS, Kryonaut between the IHS and water block, liquid cooled with the Koolance ERM-2K3U cooling unit.
I saw a -15c temp drop delidding my 7700k.
If you used similar and have good cooling, temps shouldn't be much of a problem with 1.45v.
I'm using the ROG Strix Z690-F Gaming Wifi with the 12700KF overclocked to 5.3GHz with 1.47v.
Here's a screenshot of HWinfo, click the pic to make it bigger.
