The following table shows the warning messages that may appear:
Table 16. I/O DIMM warning messages
Code Message
W2081 Unsupported DIMM type
(not 512 MB).
W2082 Unsupported DIMM type
(CAS Latency z instead of
5).
W2083 Unsupported DIMM type
(contains more data than
program buffer).
The following table shows informational messages.
Table 17. I/O DIMM informational messages
Code Message
No DIMM.
In addition to appearing on the console, messages are also written to the Advanced
Management Module log. The table below lists the messages.
The DIMM is not a registered DIMM.
The maximum I/O-frequency of the
DIMM is slower than memory
controller's frequency.
The DIMM does not provide a CAS
Latency setting for an I/O-frequency of
333 MHz or the configuration data is
inconsistent.
The DIMM does not support a Burst
Length of 4.
The DIMM has a bank count different
from 4 and 8.
The DIMM's the data width is different
from 36 and 72.
The DIMM's data-lanes are organized
other than "by 8".
The DIMM is defective.
The DIMM is defective.
Description
The DIMM has a size different from
512MB.
The DIMM is operated with CAS
Latency z, but only a CAS Latency of 5
is supported.
The SPD of the DIMM contains more
data elements than needed.
Description
The socket is not populated.
Replace the DIMM with a DIMM of type
"registered".
Replace the DIMM with a DIMM
allowing an I/O-frequency of at least
333MHz.
Replace the DIMM with a DIMM with
correct configuration data.
Replace the DIMM with a DIMM
supporting a Burst Length of 4.
Replace the DIMM with a DIMM with a
bank count of 4 or 8.
Replace the DIMM with a DIMM with a
data width of 36 or 72.
Replace the DIMM with a DIMM with
an SDRAM data width of 8 lanes.
Replace the DIMM with a new one.
Replace the DIMM with a new one.
Action
Replace the DIMM with a DIMM of size
512 MB to avoid compatibility problems.
Replace the DIMM with a DIMM with a
CAS Latency of 5 for an I/O frequency
of 333 MHz to avoid compatibility
problems.
Replace the DIMM with an SPD of 128
bytes to avoid compatibility problems.
Action
Insert a DIMM into the empty socket to
make full use of the I/O-buffer
capability.
