When you put a CPU under load the Vcore drops slightly. When overclocking this can cause instability. LLC compensates for these drops at the expense of more heat and higher transient spikes in Vcore. The higher the level the more aggressive this is.
If you want to run a manual overclock at say 1.3v then boot to windows and run a stress test if voltage drops below 1.3 then you can increase loadline a bit to make sure it doesnt drop as this may make you unstable etc. Not sure on whether 1 or 8 is highest/lowest you would have to test unless it it tells you in the manual.
Alternatively you could set vcore at 1.35 but use a lower loadline so when under load it it drops to 1.3 this way you get more voltage at single core use but still the same 1.3 at all core workloads.

apparantly the lower the number on MSI board the more aggresive the LLC is. currently settled on L2 with load Vcore at 1.325V when I have Vcore set @ 1.3V and Vram @ 1.4V when set at 1.38V

If your target is 1.325 you maybe better setting vcore at 1.35 with say an LLC of 5 or 6 so it drops to 1.325 under load that way you still benefit for higher vcore for single/lightly threaded workloads and the same 1.325 for all core. Might not make a difference but worth testing in something like cinebench.
It's for Z370 but worth a read, applies to other platforms too.
Also, Mode/Level 4 LLC is typically the recommended on MSI boards. You'll spot a little graph in the above link with Mode 4 as the flattest line, i.e. not pumping more voltage than necessary (for most scenarios).
