It is probably overheating, is there a way for you to check the thermals? If not get HWinfo
Grab the necessary applications next. Several options are ready to go, including MSI Afterburner and HWInfo.
I just looked at the MSI afterburner and noticed it’s now reporting 5.5 GHz, which is higher than the maximum allowed 5.4 GHz for a single core, but on multicore it only shows 5.1 GHz. Your temperatures during multicore runs are around 90°C. Is there an issue with Task Manager? During single-core tests it still displays below 5.2 GHz.
5.4GHz represents the highest single-thread boost capability. Multithread boost will be slightly reduced—likely around 5.05GHz. Due to features like PBO and clock stretching, clock readings become unreliable on systems newer than the Ryzen 2000 line. High clock speeds don’t always translate to better performance (as seen with my 5900X under PBO). The numbers you’re seeing are what truly matter.
MSI Afterburner displays full 5.1 channels on all cores and around 5.4 on multi-core setups. The Task Manager probably shows a lower clock speed for single-core because it averages across all cores instead of focusing on the one running at 5400MHz.
It's said that a CPU can increase its clock speed by up to its maximum possible boost before overheating, even with a high-performance cooler. In single-core performance, it only rises about 0.1 GHz above the advertised limit.
They said it wrong. Processors don’t automatically increase beyond their designed pace, and they don’t understand their own boundaries. These settings should be chosen and adjusted by the person using them.
