These tests run automatically when you start up AXD Mac OS X tools.
SMBIOS tests check to see if bad memory was detected and mapped out at Xserve
startup. When the Xserve tests memory at start up, it automatically maps out bad
memory. Mac OS X doesn’t see this mapped out memory, so the non-SMBIOS memory
tests don’t test it. The SMBIOS test reports these mapped out DIMMS.
When an ECC error occurs, memory catches the problem and and fixes it. When you
run other memory tests, the tests don’t realize an error has occurred. The ECC tests
detect these memory fixes and report them.
Estimated completion time
Compares a table of sensors and
fans with what is connected to
the logic board. If a sensor or
fan isn’t found, an error occurs.
All sensors, fans, and hard
drives found can be individually
tested using sensor, fan, hard
Checks the SMBIOS tables for
32-bit errors (type 18) and 64-
bit errors (type 33). Also verifies
that the mapped-in DIMM size
is appropriate for the slot it’s
inserted into. If there’s a size
mismatch, an error occurs.
ECC Error Count
Reports the number of
ECC errors, and then resets
