Inquiry Regarding My CPU Performance: Intel Core i7-7700K
That's rational approach and it's completely fine.
the only thing is that I'm not completely sure from you description is the sentence about locked multiplier. it's kinda better if you keep the dynamic frequency. that way the CPU can clock down (less heat and electricity) under low load. if it becomes unstable, raise a bit LLC, but just a bit.
That's a sensible approach and it's perfectly acceptable. The main concern is that in your description, the sentence about the locked multiplier isn't clear. It would be better to maintain the dynamic frequency, allowing the CPU to lower its speed (reducing heat and power consumption) during low load. If instability arises, a slight increase in LLC should suffice. Oh, so should I revert that change?

yeah if it's the speedstep
I'm not sure what everything is, so I'm attaching two screenshots that I took in my BIOS.
If you wouldn't mind, take a look and see if there is anything that I should change.
SA and IO VOLTAGE are high, I wouldn't run these higher than 1.30/1.25 respectively.
In my opinion, switching the CPU Ratio mode to whatever isn't fixed works best. Fixed mode locks the frequency. Dynamic mode allows the CPU frequency to decrease when idle or under low load.
the AVX ratio is interesting too. it indicates that executing AVX instructions (like newer prime examples) will reduce the CPU clock by -4 times the base clock, which means 400MHz less in your scenario.

I think it would be better to switch the CPU Ration mode to something not fixed. Fixed locks the frequency. Dynamic mode makes the CPU slow down when idle or under low load.
The AVX ratio is interesting—it means that executing AVX instructions (like with newer prime processors) will reduce the CPU clock by 4 times the base clock, which is a reduction of about 400MHz in your case.
I plan to change the CPU Ratio Mode to Dynamic mode. I expect this will likely lower idle temperatures significantly.
The AVX ratio I chose was based on what the OC Genie set when it was enabled. Should I tweak that?
Regarding SA and IO voltages, I didn’t adjust them myself; they’re either set by default or remain unchanged from when I enabled the OC Genie. Someone suggested lowering them, but I’m not sure. You haven’t led me astray so far, and you seem knowledgeable.
you're right about lower temperatures.
the AVX instructions are quite demanding and not very common in practice, so it's fine to keep their clock speed at a lower setting.
you might also consider reducing other CPU voltages such as SA and IO. just avoid making too many changes at once, so you can identify the issues if the system becomes unstable.
i also suggest learning about those additional voltages—SA for instance is the memory controller voltage, and its value is typically higher than the core voltage. the difference varies based on factors like MB, RAM, and overclocking settings.

This guide might be useful—it matches what I used.

"Safe Voltages (Always TENTATIVE):
Vcore: 1.45v/1.37v
VCCIO: 1.25v/1.2v
System Agent (SA): 1.3v/1.25v
Vdimm: 1.4v/1.35v
The first figure indicates voltages a daring person could handle. The next value is for regular users who prefer staying within limits."
