This guide has a link https://github.com/PrimeO7/How-to-undervolt-AMD-RYZEN-5800X3D-Guide-with-PBO2-Tuner/blob/main/README.md I would start with a higher limit on PPT/TDC/EDC unless you're actually trying to save power as a point, you're definitely leaving performance on the table starting at those values Similarly, start with -20 all core and stress test with corecycler to make sure none of your cores fail at that offset before moving up to -25 and -30

I use the PBO2 tuner from GitHub, I only adjust the cores and that’s set to -30. I’ve found that’s what works best for my setup. This is the link to GitHub, hope it helps. https://github.com/PrimeO7/How-to-undervolt-AMD-RYZEN-5800X3D-Guide-with-PBO2-Tuner/blob/main/README.md

r/AMDHelp on Reddit: pbo2 tuner doesn't work win11
January 31, 2026 -
Hey everyone, since summer started, my CPU, an r7 5700x3d, started getting really hot. Unfortunately, my motherboard is kinda old, so it doesn't have PBO for my processor. I was looking around and found the pbo2 tuner program, which has worked for a lot of people. The problem is that lately, Windows Defender is flagging the program's driver as malicious and won't let me take it out of quarantine, even after excluding the folder, etc. I hope someone can help me out with this because I've tried everything, and the program runs, but it doesn't change the voltages.

Unfortunately, PBO2 Tuner uses the WinRing0 driver to communicate with the CPU. That driver is old and has vulnerabilities. Since last year windows marks the drive as malicious and removes it. This prevents PBO2 Tuner from working. The developer has decided not to update the program as there is currently no other way for him to achieve thr dame functionality. This driver was widely used by other software used to control RGB, Fans or HW devices. They all had to update their software to a different solution.

That's weird, I managed to get it working without getting flagged just by using folder exclusion, and I can do anything like apply offsets, limit wattage, mhz, etc...
