I've recently built a new PC and noticed that my AMD Ryzen 7 9800X3D sometimes throttles down to a mere 0.6GHz, even though temperatures remain low at around 30 degrees Celsius. Initially, everything was running smoothly, but after a few days, I've encountered this problem repeatedly. I've reset the BIOS to defaults, cleared the CMOS, and even observed that the CPU performs well with speeds reaching 4.6-4.7GHz during stress testing with Prime95. Meanwhile, I'm using an older CPU cooler, so I'm concerned that may be part of the issue. Any advice on what could be causing this throttling?

I recommend downloading HWiNFO64 to monitor your CPU more accurately. While Task Manager might show it throttling, HWiNFO64 provides detailed stats. Also, double-check for any software that could be limiting your CPU performance, like eco mode settings in tools such as Armoury Crate.
You might want to check if your motherboard's BIOS is up to date. Sometimes, manufacturers release updates to improve compatibility and performance, especially with newer CPUs. Also, considering a new CMOS battery might help if the current one is failing to hold settings properly.
