You're just starting out with overclocking and undervolting, so don't worry. I previously tried -25°C +200MHz and it crashed quickly in Aida64, also stressing the FPU. Now I'm adjusting to -20°C +200MHz with PBO Scaler at level 1. It's unclear if this is normal or expected behavior, but power limits remain set to auto. Your hardware specs are: AMD Ryzen 9800X3D MSI B850 Tomahawk Wifi 32GB DDR5 6000 CL36 RX9070XT.

Don't worry, give it a shot. For instance, my 3600 was around -50mV (I don't remember the precise figure, it was early PBO days, but definitely negative), and then a +200MHz boost helped very little except with huge power draw. Switching to -200MHz improved performance by about 10%, used more power (130W), but kept things cooler—making sense since higher temps let for better gains.

When it functions, it does. When it fails, it doesn't.

Thanks for the feedback, it’s functioning as expected. I was wondering if this outcome was anticipated. Since I’m still getting familiar with it, I’ve tried everything since this update and it appears to be stable, so I’ll keep that in mind.

You're referring to running a tool like Prime95 to verify calculations after adjusting voltage or overclocking. That’s necessary to prevent data loss, as such changes can damage your system.

Other tools like Prime95, Aida64, Cinebench are also being used. Long-term testing is being conducted to assess stability.
