The following table describes the MRC fatal errors that could appear in an X8450 IPMI sensor error message.

Error Number

Description

0xE0

PCA9554 not present. Unknown expander type.

0xE1

DIMM Population issues. No memory found.

0xE2

Unsupported Ratio Error. System Frequency / FBD Frequency combination is not supported.

0xE3

MRC input data doesn't match hardware. Issues with DIMM tables, SMB devices.

0xE4

General SMBus transaction errors. Unable to process Block Mode transaction due to SECOND_TO_STS bit set. Byte offset exceeds byte count.

0xE5

A RESET to a FBDIMM branch failed. The State register was written with a RESET command, but the STATUS failed to indicate that the reset was successful.

0xE6

Channel Training Errors. In Single Channel Mode, neither branch trained successfully. Branch failed to INIT. Branch failed to go READY. Issue with tRRL skew limit. Channel RESET failure. Maximum number of RESET tries exceeded.

0xE7

0xEA

A check of the AMB stepping indicates that the part is at the end of life. Checks are made against Intel AMB A0, NEC AMB A0/A1, IDT AMB A1.0/A1.1/A1.2, IFX AMB A0.

0xEB

Failure reading the frequency strapping bits of the CK410B. Failure to enable spread spectrum capability of CK410B. Failure with one of serveral commands to the DB devices (DB1900/DB1200).
