Chapter 11: Troubleshooting

counts the memory as the test is being performed. When the test is completed, the number in this line
should equal the number in the second line. A fourth line, “Memory Errors Detected”, will occur only
if the memory test found errors on this latest test pass. It will not occur if the memory test found
errors on previous boots; however, in that case, the size in the second line will be smaller than the first
line.
NOTE: There is a 2 GB fixed gap between the memory address 2 GB to 4 GB, which is
occupied by PCI gap, system flash address, and other fixed addresses. This 2 GB
of memory address space will not be available for ‘Configured’ memory. For
example, if a system has total installed memory of 64 GB, the maximum useable
memory in the system will be (64 GB – 2 GB) = 62 GB. In this case, the
“Configured” line will read 62 GB. As mentiioned above, the “Tested” line will
count up and its final value will always be equal to the “Configured” line
(assuming all the memory is good, this will be 62 GB in this example).
