i7-8700k @ 4.7
Asus ROG Maximus X Hero
16gb Gskill Trident Z @ 3600
Noctua d-15

Hello,
I just got my new build and am starting to prepare for future overclocking while also adjusting some auto settings. I'm relatively new to this process. When left running with only XMP enabled for RAM, the motherboard was reporting close to 1.4v on the Vcore—something I've read is considered too high. To address this, I turned off Asus Multicore Enhancement, set my "sync all cores" to 47, and adjusted the Vcore to 1.25. The system started up smoothly, and the Vcore remained stable at 1.248 during idle and slightly higher at 1.280 under load, without any voltage droop.

I haven’t yet run a long Prime95 test, but checking HWinfo64 showed my CPU requesting more voltage than before (VID). It would approach 1.4 before the BIOS updates, but now it consistently asks for 1.45 and up to 1.5v. From what I understand, the VID reading reflects the CPU’s voltage request, while the Vcore is the actual supply. Is this suggesting my Vcore is too low, or is this just normal behavior?

Thanks.

VCORE in HWmonitor/HWINFO64 represents the voltage the CPU asks for from the power delivery system on the motherboard. VID is the actual voltage delivered to the CPU cores. It might be that your vboosting is quite intense. Consider changing your load line calibration (LLC) setting to level 1 and observe the results.

Yes, that's correct. I'm confirming the swap of VCORE and VID as requested.

I adjusted IA ac loadline and IA dc loadline to 0.01 and it resolved the issue.

Ok good glad you fixed it.
