Overclocking help

[HuskyGT]

Hello! So I have an 8600k that I've been working on for the past days. I just have a doubt. I'm new to overclocking, so I'm not sure of what I'm seeing here right now.

So I aimed at a safe overclock, pretty much locking all 6 cores at turbo frequency. It worked well (4.3) but I felt it was running too hot, upwards to 77c on Aida64 stress test. I had previously not messed with the voltages and left it on Auto. To my surprise, the system was pushing 1.35v to Vcore. That seems too high...

I manually set the voltage and been playing around with it for about two days. Right now I'm at 4.5GHz on 1.15v with temps at 65c max after an hour on Aida64.

Isn't the voltage way too low to sustain this overclock? Could it be that the manual clock frequency override is not registering? I mean, it does show 4.5GHz on the task manager, Aida64, CPU-z and Core Temp.

Did I get a good chip, is this normal or did I mess up something?

Should I go for 4.6GHz, or try lowering the voltage just a tiny bit more?

I can't find anything online because everyone is just crazy for 5.0GHz on these things.

I have an Asus Rog Strix z370-e just for ref.

If the voltage is too low, you will crash.

Use OCCT, it will put more load on the CPU than AIDA64

You can try higher if you want but the temps will go higher, if you're happy with your current overclock you can try lowering the voltage down a bit, stress test again.

Managed to lower it to 1.10v without crashing during an hour stress test. But as soon as I started playing a game, I got constant lockups which required hard resets. It's kind of strange since the game doesn't push the CPU past 40%.

I upped the voltage to 1.14v (still a tiny bit less than what I had)just to be sure and I've been playing for hours now. So I guess I'll leave it as is. It stays within the 50's during gaming, so I am happy with that.

I'm not looking for records or bragging, so 4.5Ghz @1.14v for a 6 core CPU seems good enough for me. This thing is already blazing fast even stock.

Games will stress test other parts of the PC.

Lowering voltage after an OC is not bragging, less voltage means less heat.

I could get 5Ghz with my i5 6600K but the voltage has to be 1.45v which is not very good and the temps are over 80°C.

I could lower the temps but that would require, delidding the CPU and draining my water cooling loop.
I recently done this so not going to do it again.
