this was extremely cringeworthy to read and literally made me not want to look at forum posts for an entire day.
Were you using offset (DVID)/Auto voltages or fixed (manual) override voltages?
If you were using override voltages, the (Internal VR Settings), AC/DC loadline values (presets in CPU Internal AC/DC Load Line for these) have absolutely ZERO effect on your voltage!
Why did you say that the "Extreme" settings for CPU Internal AC/DC loadline helped you? The AC/DC loadlines are *only* used when you are either using Auto voltages, DVID offsets, or SVID offset (Svid offset is really weird; it adjusts a voltage offset via SVID based on the type of load being delivered; SVID offset = Enabled + AC loadline = 1.0 mOhms (100 in the bios) works well at 5 ghz on some CPU's).
Anyway, regardless. What you said about extreme CPU internal AC/DC loadline preset working better at 5.1 and 5.2 ghz is wrong. Manual voltages ignore the AC/DC values totally. The CPU VID is influenced by this, but not the CPU Vcore/VR VOUT or IOUT/POUT etc. What happened when you used a *manual* voltage at 5.1 ghz or 5.2 ghz, and you set CPU Internal AC/DC loadline to power saving? There should have been zero difference in stability, as long as your "Loadline Calibration" and "CPU Vcore" were set to the exact same values, as they were when you set CPU Internal AC/DC loadline to "Extreme".
The presets for CPU Internal Load Line change the AC/DC loadline settings in internal VR settings to certain values, if they are set to 0 (auto) there:
Extreme: 2.1 mOhms/2.1 mOhms (ACLL=210, DCLL=210)
Turbo: 1.6 mOhms / 1.6 mOhms (ACLL=160, DCLL=160)
Performance: 1.0 mOhms / 1.3 mOhms (ACLL=100, DCLL=130)
Power Saving: 0.4 mOhms / 1.3 mOhms (ACLL=40, DCLL=130).
These only affect CPU Vcore (VR VOUT) on auto/SVID offset/Normal voltages only.
On Auto voltages, or if DVID is +0.00v, CPU VID will equal CPU VR VOUT if the DC loadline value is equal to the VRM (CPU Vcore Loadline Calibration) mOhms value. DC loadline does not affect voltages--it's for power measurements only (VID and CPU Package Power).
VRM Loadline Calibration presets (aka CPU Vcore Loadline Calibration):
Auto/Normal/Standard: 1.6 mOhms
Low: 1.3 mOhms
Medium: 1.0 mOhms
High: 0.8 mOhms
Turbo: 0.4 mOhms
Extreme: 0.2 mOhms
Ultra Extreme: 0.01 mOhms.
Total CPU Vdroop= Amps * Resistance (mOhms). Bios target voltage (converted to millivolts)- vdroop (mv)=VR VOUT (convert back to volts from millivolts)
Higher levels of Loadline Calibration greatly decrease transient voltage response (stability) at heavier amps loads.
