Memory settings

About this task

In the BIOS, access Memory Settings to view details.


  1. To view the Memory Settings screen, power on the system and press F2.
  2. Click System Setup Main Menu, System BIOS, and then Memory Settings.

    The following table describes options that are available:

    Table 1. Memory Settings detailsThis table describes the BIOS Memory Settings details.
    Option Description
    System Memory Size Specifies the size of the system memory.
    System Memory Type Specifies the type of memory that is installed in the system.
    System Memory Speed Specifies the speed of the system memory.
    Video Memory Specifies the size of the video memory.
    System Memory Testing Allows you to control whether the system memory tests are run during system boot. The two options available are Enabled and Disabled. By default, this option is set to Disabled.
    Memory Operating Mode By default, this option is set to Optimizer Mode. The Fault Resilient Mode and NUMA Fault Resilient Mode options are available for support when the Advanced RAS capability processor is installed on the system.
    Current State of Memory Operating Mode Specifies the current state of the memory operating mode.
    Fault Resilient Mode Memory Size (%) This option allows you to define the percent of total memory size that the fault resilient mode uses, when in Memory Operating Mode. If the Fault Resilient Mode option is not selected, it is unavailable and not used by Fault Resilient Mode.
    Node Interleaving Enables or disables the Node Interleaving option. Specifies if the Non-Uniform Memory Architecture (NUMA) is supported. If this field is set to Enabled, memory interleaving is supported if a symmetric memory configuration is installed. If the field is set to Disabled, the system supports NUMA (asymmetric) memory configurations. By default, this option is set to Enabled.
    ADDDC Settings When the Adaptive Double DRAM Device Correction (ADDDC) option is enabled, failing DRAMs are dynamically mapped out. When set to Enabled, this option impacts the system performance under certain workloads. This feature is applicable for x4 DIMMs only. By default, this option is set to Enabled.
    Memory Training When option is set to Fast and the memory configuration is not changed, the system uses previously saved memory training parameters to train the memory subsystems. System boot time is also reduced. If the memory configuration is changed, the Retrain at Next boot is automatically enabled, forces a single full memory training step, and then returns to Fast afterward. When option is set to Retrain at Next boot, the system performs the one-time full memory training step at next power on, and slows the boot time on next boot. When option is set to Enabled, the system performs the force full memory training steps every time the system powers on. This option also slows the boot process each time.
    Memory Map Out This option controls the DIMM slots on the system. This option is set to Enabled by default. It allows you to disable system-installed DIMMs.
    Correctable Error Logging Enables or disables correctable error logging. By default, this option is set to Disabled.
    DIMM Self-Healing (Post Package Repair) on Uncorrectable Memory Error Enables or disables Post Packing Repair (PPR) on uncorrectable memory error. By default, this option is set to Enabled.
