Sensor Type
See Table 30.3 in [IPMI_1].
0xC for memory errors
Sensor Number
Number of sensor that generated this event
Unique value for each type of event because IPMI
specification requires it that way. This field has no other
significance. Should not be displayed to the end user if
the event is logged by BIOS.
Type code
0x6F if event offsets are specific to the
sensor
0x6F
Event Data 1
7:6 00 = unspecified byte 2; 10 = OEM
code in byte 2.
5:4 00 = unspecified byte 3; 10 = OEM
code in byte 3. (BIOS will not use encodings
01 and 11 for errors covered by this
document.).
3:0 Offset from Event Trigger for discrete
event state.
Follow IPMI definition. If either of the two data bytes
following this do not have any data, that byte should be
set to 0xff, and the appropriate filed in event data 1
should indicate that that it is unspecified.
According to Table 30.3 in [IPMI_1], 3:0 is 0 for single bit
error and 1 for multi-bit error.
Event Data 2
7:0 OEM code 2 or unspecified.
For format rev 0, if this byte is specified,
7:6 Zero based Memory card number. Matches the
number of Type 16 entry in SMBIOS table. For example,
card 0 corresponds to the first Type 16 entry in SMBIOS
tables. If all DIMMs are onboard, this field will always be
0.
5:0 Zero based DIMM number on the card. DIMM 0
corresponds to the first Type 17 record in the SMBIOS
tables for that memory card.
Event Data 3
7:0 OEM code 3 or unspecified.
If format rev is 0 and if this byte is specified,
Syndrome Byte.

Error Type
Event Data 1
Event Data 2
Event Data 3
Single-bit error; no information about the error is
available.
00 0xFF
0xFf
Multi-bit memory error, failed DIMM is the fifth DIMM on
the second memory card.
0x81 0x44
(Bits 7:6 = 01
Bits 5:0 = 04)
0xFF
Single-bit error. Syndrome is 0x54, DIMM location is not
known.
0x20 0xFF 0x54
Multi-bit error, Syndrome byte is 0x1c. DIMMs are
onboard, and the second DIMM has failed.
0xA1 0x01
(Bits 7:6 = 00
Bits 5:0 = 01)
0x1C
