Key properties¶
Local properties¶
uint16
ErrorDataOrder
The ordering for data stored in the ErrorData property. “Least Significant Byte First” (value=1) or “Most Significant Byte First” (2) can be specified. If ErrorTransferSize is 0, then this property has no meaning.
ValueMap Values 0 Unknown 1 Least Significant Byte First 2 Most Significant Byte First
uint32
ErrorTransferSize
Deprecated! The size of the data transfer in bits that caused the last error. 0 indicates no error. If the ErrorInfo property is equal to 3, “OK”, then this property should be set to 0.
uint64
StartingAddress
The beginning address, referenced by an application or operating system and mapped by a memory controller, for this Memory object. The starting address is specified in KBytes.
uint64
ErrorAddress
Deprecated! Specifies the address of the last memory error. The type of error is described by the ErrorInfo property. If the ErrorInfo property is equal to 3, “OK”, then this property has no meaning.
uint64
EndingAddress
The ending address, referenced by an application or operating system and mapped by a memory controller, for this Memory object. The ending address is specified in KBytes.
string
ErrorMethodology
ErrorMethodology for Memory is a string property that indicates whether parity or CRC algorithms, ECC or other mechanisms are used. Details on the algorithm can also be supplied.
string
OtherErrorDescription
Deprecated! Free form string providing more information if the Error Type property is set to 1, “Other”. If not set to 1, this string has no meaning.
boolean
Volatile
Volatile is a property that indicates whether this memory is volatile or not.
uint8[]
AdditionalErrorData
Deprecated! An array of octets holding additional error information. An example is ECC Syndrome or the return of the check bits if a CRC-based ErrorMethodology is used. In the latter case, if a single bit error is recognized and the CRC algorithm is known, it is possible to determine the exact bit that failed. This type of data (ECC Syndrome, Check Bit or Parity Bit data, or other vendor supplied information) is included in this field. If the ErrorInfo property is equal to 3, “OK”, then AdditionalErrorData has no meaning.
boolean
SystemLevelAddress
Boolean indicating whether the address information in the property, ErrorAddress, is a system-level address (TRUE) or a physical address (FALSE). If the ErrorInfo property is equal to 3, “OK”, then this property has no meaning.
uint8[]
ErrorData
Deprecated! Data captured during the last erroneous mebmory access. The data occupies the first n octets of the array necessary to hold the number of bits specified by the ErrorTransferSize property. If ErrorTransferSize is 0, then this property has no meaning.
datetime
ErrorTime
Deprecated! The time that the last memory error occurred. The type of error is described by the ErrorInfo property. If the Error Info property is equal to 3, “OK”, then this property has no meaning.
uint64
ErrorResolution
Specifies the range, in bytes, to which the last error can be resolved. For example, if error addresses are resolved to bit 11 (ie, on a typical page basis), then errors can be resolved to 4K boundaries and this property is set to 4000. If the ErrorInfo property is equal to 3, “OK”, then this property has no meaning.
uint16
ErrorAccess
Deprecated! An integer enumeration indicating the memory access operation that caused the last error. The type of error is described by the ErrorInfo property. If the ErrorInfo property is equal to 3, “OK”, then this property has no meaning.
ValueMap Values 1 Other 2 Unknown 3 Read 4 Write 5 Partial Write
boolean
CorrectableError
Boolean indicating that the most recent error was correctable. If the ErrorInfo property is equal to 3, “OK”, then this property has no meaning.
uint16
ErrorInfo
Deprecated! An integer enumeration describing the type of error that occurred most recently. For example, single (value=6) or double bit errors (7) can be specified using this property. The values, 12-14, are undefined in the CIM Schema since in DMI, they mix the semantics of the type of error and whether it was correctable or not. The latter is indicated in the property, CorrectableError.
ValueMap Values 1 Other 2 Unknown 3 OK 4 Bad Read 5 Parity Error 6 Single-Bit Error 7 Double-Bit Error 8 Multi-Bit Error 9 Nibble Error 10 Checksum Error 11 CRC Error 12 Undefined 13 Undefined 14 Undefined
