Ryzen 7 1800x underclocking under load

Hello everyone, my 1800x underclocks itself under synthetic loads like Primee95 AVX or IntelBurnTest. It is pretty annoying because I can run 3.9 GHz at 1.375 V and it reaches 85 degrees under IntelBurnTest, but when I set everything to auto it downclocks itself 3.3 GHz under the same load and it hovers around 55-60 degrees. I think its AGESA related because I was using a MSI B350 PC MATE and when I updated the BIOS to a newer one the issue started to happen. At first I thought maybe AMD added a safeguard to protect cheaper motherboards VRM's. Since I couldn't roll back to a older BIOS because AMD prevents it, I changed my motherboard to an ASUS Prime X370-Pro, and then to a MSI B450A-PRO and the issue is still persistent on both of them. I don't want my CPU to reach 85 degrees when overclocked and I cant afford better cooling options so I want to be able to use it properly while at stock settings. Is there anyone who can help me to solve this problem?

PS.

Sorry for my bad English, I live in Turkey .
