No memory detected.
This alarm is generated during BIOS startup when any of the following occurs:
- No DIMM is detected.
- The only DIMM is faulty.
- The only DIMM is installed in an incorrect position.
Alarm object: system
Possible Causes
- A DIMM is incompatible with the server.
- The only DIMM is faulty and therefore isolated by the BIOS.
- The only DIMM is installed in an incorrect position.
- Signals are abnormal because the memory slot is faulty or has foreign objects.
Procedure
- Check whether other alarms are present.
- Clear other memory alarms. Then, check whether this alarm is cleared.
If yes, no further action is required.
If no, go to 3.
- Check the CPU and DIMM models.
- Check whether the CPUs and DIMMs are compatible with the server using the Computing Product Compatibility Checker.
- Replace the DIMMs with the ones that are compatible with the server and CPUs, and ensure that the DIMMs are installed in the correct position. Then, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 8.
- Replace the DIMMs with the ones of the same model, and ensure that the new DIMMs are installed in the correct position. Then, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 8.
- Replace the mainboard. Then, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 8.
