Issue

In very rare circumstances, it is possible that a DIMM failure during POST could cause the system to hang without any indication of the error.

Affected configurations

The system may be any of the following IBM servers:

  • System x3550, type 1013, any model
  • System x3550, type 1913, any model
  • System x3550, type 7978, any model
  • System x3650, type 1914, any model
  • System x3650, type 7979, any model

This tip is not option specific.

This tip is not software specific.

Additional information

If a system hang occurs, restart system, and verify error LEDs and system event logs to isolate source of failure.

If a DIMM failure occurs in the brief window after memory has initialized, but before the System Management Interrupt handler loads, the server may hang with no error. Upon reboot, the failing DIMM will be detected and flagged.
