Help with overclocking

I have a 8600k and a gigabyte z370 Ultra gaming and I’m having trouble with the vcore for overclocking when I manually change it it will boot just fine into windows but when I run a stress test the core drops to way below what I set it at, I have it a 1.32v and when I stress test it only will give me 1.28v in Hardware Monitor and before the test it shows the correct voltage, any tips on to what might be causing it iv disabled everything that is recommended for overclocking but it won’t budge over 1.28v, I am newer to overclocking so any tips on where to start?

That is because of a setting called LLC (load line calibration) it causes vcore to drop when he cpu is pulling more power. Try turning the setting up to medium or high or turbo (turbo raises voltage under load). LLC can be found under voltage then advanced power settings in your bios.

Yea, this is correct.

 

I would google the motherboard you have (or at least the manufacturer as usually each manufacturer has different settings that are known to be "correct overclocking LLC settings" to see what yours should be.

 

Basically, to explain what is happening, when you hit the CPU with a load you get what is called vdroop, the voltage drops due to the load being applied. LLC helps combat that, when it senses a large load, it applies more volts to try and compensate.

I have looked at that but the option that was changed in the guide I was using changed it but my motherboard doesn’t have a option to change it with a drop down menu so should I just type in turbo to change it? all it allows me to change with a drop down is the ac/dc load line and not the load line calibration

It should say 'Cpu VCore Load Line Calibration' in voltage > advanced power settings, on the recent bios's but if it doesnt you should just look around and try to find where it is hiding, if you cant find it after looking, check the manual that comes with the motherboard.

I see it but it doesn’t have the option to change it like the ac/dc option does, I’ll look at the manual but it’s just weird that it doesn’t have a drop down menu to change it to turbo when I click on it I don’t get any options

Also on the vcore next to the 1.325 I put in it only shows 1.3v so idk if that is also a factor

So the manual said nothing about changing it, is there a chance the newer bios update locked it out ? I’m on f14 for the Gigabyte Z370 Ultra gaming

Found it out u have to type it in and make sure to capitalise the t in turbo for it to work
