I just dont understand why "VID" is in the 1.380's range, and Vcore is 1.279v Loaded.... This is normal right, and 1.279v 100% loaded should be safe i would think right?
Can you pass this same test with only "Stress FPU"?
Having stress CPU, FPU and Cache all selected at the same time puts a very low load on the CPU.
I also can't answer your VID question. My VID at 5.2 ghz is 1.305v at idle. VID is basically a quality rating for the processor, and is used by Intel to calculate the processor's "Voltage request" via AC Loadline, with the target being an AC Loadline value of 1.1 mOhms, DC LL of 1.1 mOhms and VRM Loadline (Loadline Calibration) of 1.1 mOhms---LLC3 on Asus boards, LLC: "Standard / Normal" on Gigabyte boards, etc.
Base VID (you can see base VID with SVID Behavior on "best case scenario") or ACLL / DCLL at 0.01 mOhms is the VID shown at idle, also known as " vCPU ".
vCPU will rise up or down depending on temps...starting at 100C, and dropping 1.55mv every 1C temp drop (-1.55mv / 1C), so if your CPU is at 0C, your base VID will be 155mv lower than it would be at 100C.
Disabling "Thermal Velocity Boost Voltage Optimizations" in your BIOS will treat the vCPU as if your CPU were always at 100C, which can be useful in some situations, if you need a "higher" vCPU at lower temps.
Laptops use these Serial VID by default, via direct Serial VID (Offset mode with a 0mv offset, basically). Desktops will use VID this way also, but will only calculate vcore via VID in offset or adaptive modes.
Loadline calibration on laptops is fixed at 1.1 mOhms. On desktops, the lowest level starts at 1.7 mOhms (Asus) and 1.1 mOhms (Gigabyte), with each higher level reducing vdroop by a certain PERCENTAGE of the base vdroop loadline (a lower mOhms value of LLC=lower vdroop).
Easy math example of vdroop:
200A IOUT: (amps).
vTarget: 1.350v set in BIOS, fixed vcore.
1350mv - (200 * 1.1) = 1.130v VOUT (Loadline=intel spec defaults of 1.1 mOhms, or Level 3 LLC on Asus).
1350mv - (200 * .485) = 1.253v VOUT (Loadline=0.485 mOhms, or Level 6 LLC on Asus, LLC Turbo on Gigabyte Z490, etc).
Level 4 LLC on Asus is 0.97 mOhms, btw.
Anyway, that was for fixed voltage.
For offset voltage with a "0mv" offset (not "Auto" offset!!!):
Vcore = vCPU + (amps * ACLL mOhms) - (amps * VRM LLC mOhms). Remembering that vCPU will rise/drop depending on temps also (unless you disable TVB voltage optimizations).
This is exactly how LAPTOPS get their vcore always.
On laptops, OVERRIDE VOLTAGE doesn't set Vcore. it overwrites the vCPU completely with your override value!
Gigabyte Z490 Aorus master and extreme have an "Override" voltage and "Fixed" voltage.
For Asus, you should use adaptive voltage and you can train your "AC Loadline" by the AI options (I still am not fully sure about this procedure), and keep your LLC at level 4.
