Ryzen 7 1800x underclocking under load

Question asked by murmeko on Feb 8, 2020

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?
