Is this CPU Overclock okay?

[Okaychief]

Hi, I am fairly new to overclocking and decided why not overclock my i7 9700k after *finally* being able to get a 3080. I have set my Core Voltage to 1.31 and ran Intel Burn Test and AIDA64 stress test and Cinebench R15 with no crashes or anything.

I have a strix z390 gaming-F mobo and a rm850 80+ gold psu if that means anything to the overclocking gods

 

Current OC is 5Ghz all cores no AVX offset

 

 

Here is a picture of my CPU-Z

Here is a picture of my CPUID HWMonitor with voltages etc

I guess my question is does everything look good? Does the Voltages look okay etc? I followed THIS guide on youtube  for the most part and the only thing i changed different to him was the CPU VCCIO Voltage to 1.15000 and CPU System Agent Voltage to 1.10000 with no AVX offset.  I would appreciate some feedback, thanks alot

What LLC setting did you use? I expect voltage drop from idle to full load, say 1.35 to 1.3

Ah forgot to post my LLC sorry, My LLC is level 6

Then is idle voltage higher than full load voltage?

Idle seems to be bouncing between 1.314 V and 1.305 V 

 

When playing games it's 1.323 V

 

I believe in bios i set the cpu vcore to 1.31

So voltage is going up with manual voltage, then LLC is set too high. I thought bigger levels was less LLC with Asus, but I guess it's now the opposite so maybe you should try level 3 and see what it does.

which is never the case and never should be.

Okay, i will set the LLC to 3 and report back in a sec

I changed it to level 3 and it instantly gave BSOD when saving and exiting bios so i set it to level 5 and it seems to go from 1.305 to 1.296 when idle

changing LLC settings with the same set voltage affects the full load voltage while the idle voltage stays largely the same. LLC literally compensates for voltage drop as current draw increases, but voltage controllers do badly with voltage regulation (i.e. keeping the voltage line flat) when LLC is too high which is why I target 50mV drop from idle to load at least.

I'm largely new to this whole thing, What do you suggest i do? or are things okay?

 

Thanks for the help, it means alot.

Try use 1.35V set and level 3 LLC. Otherwise you could try auto LLC and see which level it uses (typcially no LLC is what auto uses)

Tried this, I am getting 1.332 V idle now

what about full load? That's what matters because that's when the CPU uses the most power

I put the Vcore to 1.310 again and the LLC to level 6.

 

Idle i seem to be getting 1.305 and on load i get 1.323

more voltage under load than idle is a clear sign of too much LLC. It's overcompensating.

should i try LLC 4 or 5?

I'd use LLC 3 and raise voltage till stable. Then check the idle and full load voltage during use

 

bascially, dont be fooled to think that entering a smaller number into the BIOS is better. It's not so simple.

Okay, I will try this. will report back in a few

I tried LLC 3 and raised voltage to 1.35 and when i open Cinebench R15 the program freezes and disappears from task manager but remains on screen unable to remove without restart

 

I started a game (World of warcraft) and the voltage seems to stay around 1.332

Then go even higher, say 1.38v, still safe for idle. Looks like this CPU needs about 1.32V minimum for all stress test to go well. Do you remember voltage it uses to pass all testing initially?
