I've got a 13600K and a MAG B760M MORTAR WIFI.
Cooler is a Peerless Assassin 120 with two NF-A12x25.
TL;DR: Is it safe to combine LLM 1 and LCC 1 with a -0.155v undervolt?
As in, is it doing some long-term harm because having X and Y means X is sending to much current, especially because your offsetting with Z..
I decided to mod a PC case so I've only had the PC powered on once during the last ~3 months.
Today I put it in the new case and wanted to try a setting I was recommended so I ran some tests.
I've been using Lite Load Mode (LLM) set manually to 12 because the Auto = 12 is more like LLM 16.
But anything less than 12 lowers performance slightly with each step down and drops sharply at LLM 7 or LLM 8.
I ran it with "No UVP" but IA CEP still affects the performance if you change LLM but I can undervolt via CPU Core Voltage Offset.
I could run OCCT and CB R23 with a -0.160v offset; OCCT crashed with a -0.170v offset.
For reasons (I think I felt I was losing out on performance) the last settings I had were with a -0.050v offset.
Here's the first test from today:

Then I tried the setting I was recommended which was LLM 1 (which I've tried, tanks performance) but also set CPU Loadline Calibration Control (LCC) to 1.
I found a comment on a video that said that setting CPU Loadline Calibration Control to 1 stops Lite Load from tanking performance.
LCC is found here:

With UVP enabled (which ignores the offset) I got this:

With No UVP I got this:

That's a big difference!
I know the Intel recommendation is to enable UVP but it's a 23C degree difference and the voltage looks lower too.
I still haven't updated to the latest BIOS (I read the current x125 lowers performance and raises temps) but I'm planning on updating when the mid August version releases; I'm waiting on the reviews.
If it's bad I'll go back to the LCC Auto setting with the same offset and No UVP and manually set it at LLM 12.
Maybe a recommendation would be, e.g. LLM 9 and LCC 3, or LLM 2 and LCC 2.
So LLM 1 and LCC 1 with Current Limit (A): 307, PL1: 200W, PL2: 220W
I'd really appreciate it if you could let me know if the above is at least a safe setting!
Thanks!
