Yeah if you have any questions just ask, because I have a Z490 Master in front of me, trying to compare two CPU's--note--10900k's not 10700k's, so off topic for this thread (my ES and my retail) that have the same VIDS, up to 5.2 ghz, where the retail chip takes a crap (25mv higher VID at 5.2 ghz, plus i'm using air cooling on that open bench setup) which makes 5.2 VERY hard to stabilize (The ES, with a 360 AIO, can do 5.2 (and is game stable at 5.3) but I run out of temp headroom in Realbench 2.56 at 5.2 ghz, >1.250v die-sense (true) load voltage, so the CPU Cache L0 errors start past 90C...).
The tool isn't that useful at the moment since it can't be run with other monitoring programs like HWinfo64, but at least you can get your real voltages now, which as you can see are much lower than what the sensors say at full load.
As far as the Presets for "CPU Internal AC DC Load Line", I don't know what the presets are, but I know what they were on the Z390 Master.
I calculated the exact Vcore loadline calibration "resistance" (milliohm) values on Z490 thanks to Shamino's tool, and I assume the relationship between the AC/DC Loadline "presets" and the Loadline calibration levels are still the same.
Vcore Loadline Calibration:
Standard/Normal: 1.1 mOhms
Low: 0.85 mOhms
Medium: .68 mOhms
Hiugh: .55 mOhms
Turbo: .29 mOhms
Extreme: .185 mOhms
Ultra Extreme: 0 mOhm
If the same relationship between the AC presets and LLC values still exist, then the CPU Internal AC DC Load Lines should be:
Extreme: AC: 1.7 mOhm, DC: 1.7 mOhm (Bios values in Internal VR Settings->Core IA VR Enable/Config--> AC Loadline: 170, DC Loadline: 170)
Turbo: AC: 1.1 mOhm, DC: 1.1 mOhm (110/110)
Performance: AC: 0.68 mOhm, DC: 0.85 mOhm (68/85). <--on the Z390 Aorus Master, LLC "Low" was 1.3 mOhms, LLC Medium was 1.0 mOhm, and AC/DC Load Line="Performance" was 1.0 mOhm/1.3 mOhm)
Power Saving: AC: 0.29 mOhm, DC: 0.85 mOhm (29/85).
The raw numbers in parenthesis are the values you would have to enter into the Internal VR Core IA settings. Note that the Internal VR Core IA has higher priority and overrules the "preset" options.
The "AC Loadline" helps the CPU request a supply voltage from the VRM, in Auto vcore, Adaptive and Offset voltage modes (offset mode applies an offset to this). This formula is too complicated for me to explain here. Every time I try, no one ever understands (simple math) and they start asking more questions... :/
DC Loadline is used for "Prediction" of the vdroop (basically it predicts the loadline calibration level if you set it to it) and shows the results as "CPU VID". This is used for power reporting ONLY, not for actual voltage!!
