Severity Description
Error An error occurred while initializing one
I/O-buffer memory module.
Action
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
1 GB 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.
