The preceding example output includes 8 DIMMs. Note the following in this output:
◦ Information about the first DIMM, P1-DIMM1A, is on the first line. The two lines that follow are the
DIMM repair tag, which shows that this DIMM has been encountering corrected errors.
◦ The third DIMM, P1-DIMM3A, has also encountered corrected errors.
◦ The last number on each line of inventory is 1867. This number is the channel speed that the
memory controller set at boot time for that DIMM.
