Identifying BIOS DIMM Error Messages
The system BIOS displays and logs four types of DIMM error messages on system screen and in
ILOM's IPMI SEL. The ILOM SEL format is as follows
Event# | Date | Time | Memory #0x(error type) | Configuration Error | CPU
Y
DIMM
Z
Where Y represents the processor socket that the DIMM is associated with and Z is the DIMM
socket that displays the error.
The following table describes the error details.
SEL Display Screen Display Cause of Error Message
Memory #0x01 NODE-n Paired DIMMs Size
Mismatch The paired DIMMs are not of the
same size.
Memory #0x02 NODE-n Paired DIMMs SPD
Checksum Mismatch A differences in SPD checksum
value (byte63) of a DIMM from
other DIMMs of same processor
Memory #0x03 NODE-n DIMMs Manufacturer
Mismatch The DIMM manufacturer is not
supported or recognized
Memory #0x04 NODE-n single DIMM slot is left
unpopulated The DIMM slot
"
z
"
of processor
"
y
"
is left unpopulated while it's pairing
slot has a DIMM installed.
In addition, the following error message is displayed to the screen only (not in the SEL):
NODE-
n
Memory Configuration Mismatch
The following conditions cause this error message:
■ The DIMMs mode is not paired (running in 64-bit mode instead of 128-bit mode)
■
The DIMMs’ speed is not the same.
■
The DIMMs do not support ECC.
■
The DIMMs are not registered.
■
The MCT stopped due to errors in the DIMM.
■
The DIMM module type (buffer) is mismatched.
■
The DIMM generation (I or II) is mismatched.
■
The DIMM CL/T is mismatched.
■
The banks on a two-sided DIMM are mismatched.
■
The DIMM organization is mismatched (128-bit).
■
The SPD is missing Trc or Trfc information.
