According to the error message with ECC in red, the previous code

0x04 0x0c 0x02 0x6f 0xa1 0xc1 0x40 # Memory #0x02 Uncorrectable ECC (UnCorrectable ECC | DIMMB3)

 

Determine the location of the memory according to these hexadecimal codes and replace the memory

This location is subject to the requirements of the technical documents given by the server manufacturer, because the location of each model is different~
