Question Trying to achieve 5.0GHz on my Gigabyte Z390 AORUS + i9-9900KF. Voltage is reading higher than what I set in BIOS.

Hi all, here's my specs:

Multiplier is set to 50 and VCore is set to 1.335. Here's my BIOS settings:

1. I disabled Speed Step and EIST
2. I disabled C-States
3. I set Ring Ratio to 47
4. I disabled Ring to Core Offset (Down Bin)
5. AC/DC Load Line is set to Auto
6. AVX Offset is set to 1

Here's my problem:

Everything except for CPU-Z is showing wildly higher voltages than what I have set in the BIOS. BIOS is at 1.335. AIDA64 is showing 1.392. OCCT is showing 1.394-1.396.

I followed the guide here to the best of my ability: https://www.gigabyte.com/FileUpload/Global/multimedia/2/file/525/946.pdf

Why are my voltages off the charts on AIDA64 and OCCT?

Could really use some guidance on what to do from here. I'm kind of afraid to run a stress test with these voltages.

A few thoughts on the matter:

• From what I gather, VID is what the CPU requested, VCore is what the CPU got. VID may also change anyway depending on load.
• Software measurements may not be that accurate and what's reported depends entirely on the implementation of how the reading was sampled
• The difference between 1.335 and 1.38-1.39 is only 4%, hardly what I'd call "off the charts"
• The maximum VCore is 1.5V, so as long as you're not approaching that, it's fine

Thanks a lot for that distinction. I didn't really know what VID meant, I thought it was just synonymous with VCore.

So, the VCore value in the lower half of the OCCT screenshot, under the motherboard section, is the correct VCore?

You're right. I was reading in the guide that I was following not to go over 1.35. So I kind of freaked out when I saw VID (not knowing what it actually meant) going over that threshold.

Going to try and stabilize the overclock tomorrow.
