SPI_CLK problem on MSI MPG B550 Gaming Plus
Hello. MSI Motherboard has a problem with SPI_CLK signal on BIOS chip. Startup procedure stops wich "CPU debug" led. I've checked SPI_CLK line with oscilloscope - there is only around 1.6V without traces of 48MHz oscillations - BIOS chip not sending data to CPU and everything stops. I've checked all voltages (I belive) and all EN signals - everything looks ok. Maybe someone more experienced has an idea what else to check... -
