Use the
Extended Memory Test option to configure whether the system validates memory during the memory initialization process. When enabled, and uncorrectable memory errors are detected, the memory is mapped out, and the failed DIMMs are logged to the IML.
NOTE:
Enabling this option might significantly increase boot time.
Procedure
From the
System Utilities screen, select
System Configuration > BIOS/Platform Configuration (RBSU) > System Options > Boot Time Optimizations > Extended Memory Test.
