Question CPU stress testing

[Syn89]

I have an 11900k paired with an Asus z590 Maximus extreme and i've been trying to overclock my CPU a bit, just for fun....the SP rating of my CPU is 49, which is bad...but i could get it to 5ghz all core and 0 AVX offset to be stable at 1.4 V, which is a bit high probably. Temps at full load reach 85-86. I only use the PC for gaming, no productivity, so i will never push the CPU that far in real world use. My question is, what is the difference between having a PC stable when stress testing and having it stable when i use it in games? Because i can drop the voltage to 1.33 and it doesn't crash in games. I know people tend to say you don't have a stable overclock unless it runs 24 hours on a stress test without crashing, but i repeat, i will likely never push my CPU that far the way i use it.

I do not recommend lowering the voltage to less-than-stable. The CPU will still spike to 100% and low voltage will cause errors.
I would lower the frequency and voltage to something sane and live with the performance, since you do not do computations and your real-world apps will not be capped by this CPU anytime soon, you might try using a lower clock and comparing it not to the fastest synthetic benchmark but to your personal preference of performance/noise preference.

When you say "cause errors" what would that mean? A crash or a quick drop in performance?

Crashes, data errors and similar..

I've noticed that, even though i have it set at 1.4V in the BIOS, when in full load it doesn't go above 1.23V, and idle is at 1.37. So i should be safe, heck, i could go even higher😅

It might mean it throttles. I am not sure what settings do you use and where so it is hard to tell.

Clock speeds are stable at 5Ghz, as for settings, just the standard: removed all limits, LLC is set to 4, wich is the middle setting(reccomemded for OC by Asus) sync all cores to 5Ghz, 0 AVX offset and voltage set to manual at 1.4V

I would just set an offset with intel utility, having static voltage is a bad practice in general. Check on my post here.
