Hello. So, I'm in a bit of a pickle. I'm using a pretty old motherboard Gigabyte b450 Aorus Elite, and wanted to undervolt my Ryzen 7 5800X3D cuz the temps are way too high. The package temp jumps right to 90C after a few seconds of Cinebench. Playing games also results in a very high temperature, sometimes close to 90C.
My motherboard doesn't have various PBO and Curve Shaper settings, which are covered by most guides. Reference, for example: https://www.youtube.com/watch?v=rY2nlI84S0E&t=460s
The CPU itself, from what I've read, is also restricted in overclocking by AMD. Their Ryzen Master doesn't have anything that I could change.
I've downloaded the SMU debug tool as a workaround, but I don't see any change in voltage or temps after I change values in the PBO tab. I've tried launching .exe file as admin, but it didn't change anything.
If anyone has experienced the same problem or just knows what I'm doing wrong, please let me know.
Thanks in advance.
