Can someone explain load line levels for me?

[pc-guy]

I got a MSI B450m Mortar Max

under some of the voltage settings there are load line levels. It goes up to L8 I believe.

what each level means? If I am doing mild overclocking what should I set it to.

thanks

Are you running pbo or manual all core OC?

If running pbo your best leaving it on auto.

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.

Manual, Vcore from Aida is slightly higher than what I set in BIOS. 1.3 yield 1.304 idle or underload.

just watched HWmonitor Vcore drops to aroudn 1.23

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.

i was hopign not watching his video. guess no choice.

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
