I need expert help. I bought a TopC motherboard with a mobile i9 13980hx. After unsuccessfully undervolting the BIOS, the board went into a reboot loop, specifically after enabling WDT. Resetting the BIOS to factory settings didn't help. I tried removing peripherals and RAM and discharging capacitors. The reboot loop is constant. Sometimes it enters the BIOS for a few seconds, but nothing can be done. Does anyone know how to fix it? One of the photos shows the frequency and temperature results during the OCCT test, after manipulating the BIOS. After stopping the test, the screen froze and began a cyclic reboot. Before this, a profile was configured in Intel XTU with frequencies of p-cores 5.1 GHz and e-cores 3.6 GHz, limits p1 180w -100mV, p2 220w -50mV and everything worked fine
