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
These setting are for 360 rads or custom cooled loops. (You can try this on 240+ rads, I didn’t have any to test. Use your discretion)
PPT- 120
TDC- 75
EDC- 110
And if you can you gotta try -30. Mine has been smooth since.
(For people who keep asking about automatically applying the limit section)
You just add it after those other commands for the undervolt in task scheduler.
-30 -30 -30 -30 -30 -30 -30 -30 95 60 90 0
Also here are some better settings only if you have a beast cooler. I use a 360 rad on full blast and these settings never reach the throttling max, not even in R32. In heavily bound CPU games like New world in towns I reach as high as 50% usage, never goes above 54c.
PPT- 120 TDC- 75 EDC- 110
So real world testing and artificial tests never touch the max and keeps it even cooler!
EDIT- Glad it worked out for ya bro!

Updated guide and some troubleshooting steps

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.

Try to push it a bit more? like -30 ? (Don't set it at windows boot)
It could be ryzen issue :D
with curve, you tell it to use less voltage than stock.
Like instead of 4200mhz @ 1.12V, you could go at 4200@1.10V
But you CPU temp is "lower" so it can push to 4450@1.15
Pay attention to your frequency. The reason why it can get more voltage, and more temp.
And be sure your CPU not go over 75-80°C, and everything will be fine :)
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!
