Table 15. I/O DIMM boot errors (continued) E2002 Incompatible DIMM type The DIMM is not a registered DIMM. Replace the DIMM with a DIMM of type (not registered type). ″registered″. E2011 Incompatible DIMM type (maximum DIMM frequency too slow). The maximum I/O-frequency of the DIMM is slower than memory controller's frequency. Replace the DIMM with a DIMM allowing an I/O-frequency of at least 333MHz. E2012 Incompatible DIMM type (CAS Latency). The DIMM does not provide a CAS Latency setting for an I/O-frequency of 333 MHz or the configuration data is inconsistent. Replace the DIMM with a DIMM with correct configuration data. E2013 Incompatible DIMM type The DIMM does not support a Burst (Burst Length). Length of 4. Replace the DIMM with a DIMM supporting a Burst Length of 4. E2014 Incompatible DIMM type The DIMM has a bank count different Replace the DIMM with a DIMM with a (wrong bank count). from 4 and 8. bank count of 4 or 8. E2021 Incompatible DIMM type The DIMM's the data width is different Replace the DIMM with a DIMM with a (DIMM data width). from 36 and 72. data width of 36 or 72. E2022 Incompatible DIMM type The DIMM's data-lanes are organized Replace the DIMM with a DIMM with (SDRAM data width). other than "by 8". an SDRAM data width of 8 lanes. E2031 Data error. The DIMM is defective. Replace the DIMM with a new one. E2032 Address line error. The DIMM is defective. Replace the DIMM with a new one. The following table shows the warning messages that may appear: Table 16. I/O DIMM warning messages Code Message Description Action W2081 Unsupported DIMM type The DIMM has a size different from (not 512 MB). 512MB. Replace the DIMM with a DIMM of size 512 MB to avoid compatibility problems. W2082 Unsupported DIMM type (CAS Latency z instead of 5). The DIMM is operated with CAS Replace the DIMM with a DIMM with a Latency z, but only a CAS Latency of 5 CAS Latency of 5 for an I/O frequency is supported. of 333 MHz to avoid compatibility problems. W2083 Unsupported DIMM type (contains more data than program buffer). The SPD of the DIMM contains more data elements than needed. Replace the DIMM with an SPD of 128 bytes to avoid compatibility problems. The following table shows informational messages. Table 17. I/O DIMM informational messages Code Message No DIMM. Description The socket is not populated. Action Insert a DIMM into the empty socket to make full use of the I/O-buffer capability. In addition to appearing on the console, messages are also written to the Advanced Management Module log. The table below lists the messages. Chapter 5. Diagnostics and troubleshooting 87
