Undervolting a 5800X3D with PBO2 Tuner results in higher voltage and temps?

In PBO2 go to the limit section and input…

These setting are for people with air coolers (not recommended) and 240-280 rads.

PPT- 95

TDC- 60

EDC- 90

r/Amd on Reddit: Undervolting a 5800X3D with PBO2 Tuner results in higher voltage and temps?
October 6, 2022 -

So, i have a problem.

I recently upgraded my old i7-5820K to a Ryzen 7 5800X3D. (Great CPU, the performance gains in some of my games are crazy, especially all the lows.)

My GTX 1080 is also undervolted, so i looked into undervolting the CPU too. Quickly i became aware of PBO2 Tuner and found the undervolting guide on Github.

I set PBO2 Tuner to -20 on all cores and noticed that my voltage, temps and power comsumption are higher than without PBO2. The same happens with -15 on all cores.

I did a quick benchmark to give you guys an overview. Here is the one without PBO2, stock settings: Screenshot

And here is the one with -15 on all cores, set with PBO2 Tuner: Screenshot

What am i doing wrong? I basically followed the Github-guide without the automation, watched some YouTube-videos from other users using the same method, but something is off for me.

I hope you guys can help me.

My full system, if that's important:

  • Ryzen 7 5800X3D

  • 32GB Corsair Vengeance LPX DDR4-3600 (CL18)

  • Asus ROG STRIX B550-E GAMING with the latest BIOS

  • Be Quiet! Dark Rock Pro 4

  • Be Quiet! Straight Power 11 (1200W)

/UPDATE:

Thanks for the help! Using the settings that DIMEBAGLoL provided, everything works now. Have to test -30 on all cores a little bit more, but i'm now boosting to 4.4Ghz at 70°C, have test some games and look how they do.

March 25, 2023 - Yep, the latest Asus BIOS for their X570 boards (and some other brands) lets you set CO offsets. I used the PBO2 tuner in Windows to find my stable per-core offsets, then set them in the BIOS.

Dicas para o PBO2 Tuner com 5800x3d : r/Amd
August 20, 2023 -

I’ve gone through almost all posts on PBO2 Tuner for the 5800x3d.

So far, I’ve set all clocks ranging from -10 to -30 and the best score I’ve gotten in R23 is about 14100ish. I’ve seen that it should give up to the range of 15k to 16k.

Used a variety of settings as well for PPT, TDC, and EDC but I cant get past 14.1k.

Bios firmware is up to date for my asus tuf b550m plus wifi ii.

Anything am missing? Oh and my PBO2 Tuner shows SMU Status failed after i set the limits.

Thanks!
