I've been experiencing CPU throttling issues with my Ryzen 5 2600 on an ASUS STRIX X370-F motherboard for about 6 months, but it has now become a consistent problem. Whenever I start my computer, the CPU throttles down to around 0.5GHz. In HWiNFO, I've noticed that both PROCHOT EXT and Thermal Throttling (HTC) are active during these times. Disabling PROCHOT in Ryzen Master resolves this, but all the temperature readings seem normal. I'm looking for a software solution to determine what's triggering PROCHOT since I don't have spare parts for testing. Is there a way to permanently disable PROCHOT, or any other suggestions on diagnosing this issue? Any help would be greatly appreciated!

Have you tried clearing the CMOS data? Some motherboards have issues where faulty CMOS data can trigger the CPU's throttling. Clearing the CMOS might resolve that. Also, keep an eye on CPU cooling; PROCHOT is typically activated by the CPU or VRM overheating. If the VRM phases start failing, it can lead to permanent throttling issues, so make sure your cooling is effective!
I cleared the CMOS as suggested, and it worked temporarily; the CPU ran at normal speed initially. However, after putting it to sleep and waking it up, the throttling returned. The CPU temp is around 40C, which seems fine, but I'm a bit unsure about the motherboard's VRM temp sensors' placement. I've had some luck before just by entering the BIOS and exiting, but that's not working lately.
