6.4.3.1 QPI Fatal Error and Fatal Error #2 – Next Steps
This is an Informational event only. Correctable errors are acceptable and normal at a low rate of occurrence. If the error continues:
1. Check the processor is installed correctly.
2. Inspect the socket for bent pins.
3. Cross test the processor. If the issue remains with the processor socket, replace the main board, otherwise the processor.
