Memory Settings details

You can use the Memory Settings screen to view all the memory settings and enable or disable specific memory functions, such as system memory testing and node interleaving.

To view the Memory Settings screen, perform the following steps:

3.
On the System Setup Main Menu screen, click System BIOS.
4.
On the System BIOS screen, click Memory Settings.

The Memory Settings screen details are explained as follows:

Specifies whether the system memory tests are run during system boot. Options are Enabled and Disabled. This option is set to Disabled by default.
Specifies the memory operating mode. The options available are Optimizer Mode, Advanced ECC Mode, Mirror Mode, Spare Mode, Spare with Advanced ECC Mode, Dell Fault Resilient Mode and Dell NUMA Fault Resilient Mode. This option is set to Optimizer Mode by default.
NOTE: The Memory Operating Mode option can have different default and available options based on the memory configuration of your system.
NOTE: The Dell Fault Resilient Mode option establishes an area of memory that is fault resilient. This mode can be used by an operating system that supports the feature to load critical applications or enables the operating system kernel to maximize system availability.
Specifies if 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. This option is set to Disabled by default.
Specifies the Snoop Mode options. The Snoop Mode options available are Home Snoop, Early Snoop, and Cluster on Die. This option is set to Early Snoop by default. This field is available only when the Node Interleaving is set to Disabled.
