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.
