Supermicro POST code B7 and B9 indicate a memory issue.
I have a Supermicro E5 V1 system that has been running for some time. During a recent reboot, it got stuck on B7 and B9 POST codes. I saw ECC errors in the Event Log. Here were my troubleshooting steps:
1. Swap out all 8 DIMMs (4 per CPU)
2. Move to 1 DIMM per socket
3. Go to single CPU socket
4. Swap CPUs in the single socket
5. Swap RAM in the single socket
6. Single DIMM in the single socket
All six of those configurations would land me either at B7 or B9.
My hypothesis right now is that I have a dead motherboard. I wanted to see what folks here think about that statement or if I am overlooking a step/ configuration.
Having two dead CPUs and/ or sets of RAM seems unlikely.
