LLC not high enough?

as the title says, my llc level is not high enough. i have an msi b350 pro vdh, and its bad. with the highest "mode" (mode 1) i drop from 1.406 max to 1.35v-1.36 at load. with mode 8, its in the 1.20s. is there any way to make my own mode? 

1.40 is okay for daily usage, but i really would like it to be under 1.4

I personally would rather increase the base voltage and enable all the power saving options.

no way that I know of to alter or adjust llc, you could always report it as an issue to msi, but they haven't exactly had ryzen as a high priority as far back as the prep phase before launch

wouldnt the power saving options only impact idle?

That's why you turn up the base voltage offset as well.

Those like C-states, EIST (might not all exist, AMD is not Intel so names are different)

 

It's easier to reset the BIOS and put the overclock back in, but only change the clock multiplier and voltage

Maxing out LLC is a quick way to burn your chip.  On load to no load transitions it can cause spikes far above the reported voltage on the millisecond time scale (spikes up to 1.6v,or more depending on the board, and they are short enough that you need a scope to see them).

 

You are better off just bumping the voltage up a little to get stability rather than cranking LLC.

are you sure? because of the vdroop i cant go any lower than 1.4125v and when under load its 1.36 max

It depends on the board, and yes it is measurable with a fairly high resolution oscilloscope.  I was seeing ~1.8v spikes with vcore set to ~1.5v on the setup that was killing CPU's.  I tested the board after it killed the second CPU.

 

Its just the way LLC works.  The LLC algo sees the voltage droop and increases the pwm signal to push voltage back up.  When you go to no load, the VRM has to decrease the PWM signal.  The feedback loop is not fast enough to catch those transitions before voltage spikes up quite a bit.

currently im on level 1. is that too high or too low? im not sure if its reversed or not

If level 1 give less vdroop its the "high" setting.  If that is the case, bring it down to 2 or 3 and bump your v core a little.

 

Most B350 boards are pretty terrible when it comes to vdroop because they are only 3 or 4 phase VRM's.  Even the "6 phase" or "8 phase" B350 boards are just running 3 or 4 electrical phases with doubled up components so they suffer from the same vdroop problems.

 

Heck, many X370 boards have the same problem.

meh, i dont feel comfortable running at higher than 1.4. ill just go down to 3.8. thanks for the save :)
