My computer randomly reboot without any warning. It just shutdown and reboot with no error message or bsod. This happened 3 times now. All cables to the motherboard are good. Temp is good. I can game fine for more than 2 hours.

Yes. CMW32GX4M4C3200CL16 4x8GB kit.

My BIOS is 5220 - AMD AGESA Combo-AM4 1.0.0.3 from CPU-Z

I heard latest AGESA bios have some issues.

I ran Prime95 and Unigine Heaven benchmark at the same time and no randomly restart at all. I don't know what to think the cause of randomly restart. I cannot find anything on Event Viewer that can give me a hint of what causing randomly restart.
