i7-9700KF Core Vid min/max/average
Hi guys,
I have a question about max voltage/CoreVids. How high will the spikes be? I think the maximum values appear right after running in the OCCT software. Should I focus on the maximum in Core VIDs or the average in Core VIDs?

Based on your motherboard, the optimal setting is VROUT which displays the actual voltage and then your standard 'non' VID Voltage so you see the regular core voltage. VID reflects what the CPU needs while vcore and VROUT represent what you're actually receiving—this creates a significant difference. As long as both vcore and VROUT stay under 1.35v, it meets my personal limit. For my specific CPU at 5.1GHz with a fixed vcore of 1.295v, the readings were as shown in the CinebenchR20 results and temperatures are included.
Achieving the lowest possible vcore is essential for stable overclocking and maintaining temperature control. I'm currently using the newest HWinfo version and running Prime95 blend, especially if this rig is for gaming. CinebenchR20 will help assess stability and temperatures. Remember to set LLC to prevent any vdroop; I usually begin with a middle LLC value. At first I chose 'High' on LLC but later switched to 'Turbo'.
Also keep in mind that you shouldn't require 1.35v, as that's just my personal maximum. Currently I'm using a fixed vcore of 1.295v and anything at or below 1.300v is excellent.
I have this motherboard GIgabyte Z370-HD3P. When I try to run my CPU at 4.9/5.0Ghz, what should I do?

I will monitor temperatures on the cores (under 80 degree) and VRout (under 1.35V). Is it okay?
I have seen many guides where these settings were turned off.
Enhanced Multicore Performance - Disabled
Intel Turbo boost Technology - disabled
Intel Speed shift technology - disabled
CPU enhanced halt(C1E)- disabled
C3 state support - disabled
C6/C7 state support - disabled
C8 state support - disabled
C10 state support - disabled
Package C state limit-C0/C1
Ring to core offset (down bin) - disabled
CPU EIST Function - disabled

Should I disable these settings when I want to increase the frequency?
And I saw this.
Vcore is the native value reported by the motherboard, representing the traditional method of measuring voltage to the CPU. It gauges power output at the VRM and ignores losses from resistance between the VRM and CPU (the loss through the copper in the motherboard).
VR VOUT is a newer design that ASUS likely introduced with recent models like the Rampage B350/B450, and has appeared on several Z390 boards, including yours. This is why some think there’s a hidden 100mV offset—it’s actually using the updated sensor.
The new sensor connects the CPU socket power input pin to ground and measures voltage in between. Because it’s very close to the CPU pins, it offers a more precise reading of the actual voltage delivered to the CPU, with minimal resistance.
VOUT gives the accurate measurement, but not all boards support it, making comparisons across platforms challenging.
If you have a Z370 board and don’t see VRout, should you rely only on Vcore in the HWinfo?
Check the vcore beneath the VRM Mos, there could be another one lower up, which also looks more precise.
Your success in achieving a high overclock depends largely on obtaining a suitable chip. As of 2/6/2019, the statistics from silicon lottery show varying chances based on voltage settings. For an I7-9700K, the likelihoods are as follows: 5.2% for 10%, 5.1% for 35%, 5.0% for 78%, and a perfect 100% for 4.9%. Be mindful of voltage control—it's crucial for temperature management and long-term CPU health.
