307 Appendix A: Event code tables
Event code: 426
Message: Multiple ECC single-bit errors occurred.
Severity: Minor.
Explanation: When the SDRAM controller detects an error checking and correction (ECC) error, an interrupt occurs. If an
interrupt occurs a certain number of times weekly, a 426 event code is recorded. The number of interrupts is
indicated by the event data.
Action: No action required. SDRAM is probably malfunctioning intermittently.
Event Data: Byte 0 of the event data (equal to 5, 10, 15, or 20) is recorded. The number of interrupts equals two to the power
of the event data. Event data equal to 10 indicates 1,024 ECC error interrupts.
