Appendix AXD Tools Test Reference 33
In AXD EFI tools, all memory tests (simple, multicore, extended, and SMBIOS) are
grouped under Memory tests.
Note: The time required to complete memory tests correlates to the size of memory
being tested. These estimates are based on testing 1 GB of memory
Memory (SMBIOS) Tests
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.
In AXD EFI tools, all memory tests (simple, multicore, extended, and SMBIOS) are
grouped under Memory tests.
Because memory is mapped only once, you should run this test once and not loop it.
Test Estimated completion time Description
Extended Memory Test P00F 5 seconds Tests memory using pattern 0. This
fails if an error occurs.
Extended Memory Test P01F 5 seconds Tests memory using pattern 1. This
fails if an error occurs.
Extended Memory Test P02F 5 seconds Tests memory using pattern 2. This
fails if an error occurs.
Extended Memory Test P03F 5 seconds Tests memory using pattern 3. This
fails if an error occurs.
Extended Memory Test P04F 5 seconds Tests memory using pattern 4. This
fails if an error occurs.
Extended Memory Test P05F 5 seconds Tests memory using pattern 5. This
fails if an error occurs.
Extended Memory Test P06F 5 seconds Tests memory using pattern 6. This
fails if an error occurs.
Extended Memory Test P07F 5 seconds Tests memory using pattern 7. This
fails if an error occurs.
Test Estimated completion time Description
SMBIOS Self-Test 1 second 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.
