Where ‘n’ refers to the DIMM number.
Example: Consider a system that is populated with two rows of 256 MB DIMMS in the upper board
rows 1-4 and 5-8. If a single bit memory error was detected in DIMM 5 during the first row memory
test and if no errors were found during the base memory test, the following message will appear on
the video during POST:
2048 MB Total Memory Installed
1024 MB Configured
1024 MB Tested
The first line is the total memory installed (regardless of condition). The second line is the total
memory useable (and is less than the first line, only if defective DIMMS were found). The third line
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.
The following error message for the defective DIMM 5 will be displayed on the video as follows:
“8C95: DIMMs mapped out: Lower Board, 5 - 8”
User Action
If the user is satisfied with the configured memory on the system, no action is required. Otherwise,
follow these steps:
