Po zmianie biosu nadal to samo. Napiecia na cewkach pojawiają na kilka sekund. Natomiast 8 noga SPI ma zasilanie dosłownie na ułamek sekundy po uruchomieniu laptopa
Zauważyłem nagrzewanie na sekundę układu który wymieniłem (pue1) na nóżce 5,15,16 - 0,95v_DGPU jest 56 ohm
Rozlutowalem zworke PJE1
56 Ohm po stronie GPU. Czy to zbyt nisko?
