System Memory size
Displays the amount of main memory in the system.
System Memory Type
Displays the type of main memory installed in the system.
System Memory Speed
Displays the clock frequency of the main memory.
System Memory Voltage
Displays the current operating voltage of main memory. When set to Auto (default), the system automatically sets the system voltage to the optimal setting based upon the DIMM capability and the installed DIMM population. This field also enables setting the system DIMM voltage to a higher (1.5 V) setting if the DIMMs support multiple voltages and have been Auto set to a lower voltage.
Video Memory
Displays the total amount of video memory available to the embedded video controller.
System Memory Testing
Specifies whether system memory tests are conducted. When set to Enabled (the default), the memory tests are performed. When set to Disabled, the memory tests are not performed.
Enabled (the default) | The memory tests are performed. |
---|---|
Disabled | The memory tests are not performed. |
Memory Operating Mode
Selects the memory operating mode. This feature is active only if a valid memory configuration is detected.
Optimizer Mode | The DRAM controllers operate independently in 64-bit mode and provide optimized memory performance. |
---|---|
Mirror Mode | Only half of the installed memory is reported to the OS as available. |
Advanced ECC Mode | The two DRAM controllers are combined in 128-bit mode and provide optimized reliability. Memory that cannot be teamed by the controllers is not reported to the OS. |
Spare Mode | The memory size reported to the OS does not include the spare portion. |
Node Interleaving
If the system is configured with matching memory, this field enables node interleaving. This field is active only if the memory configuration can support node interleaving. Redundant memory feature is disabled if node interleaving is enabled.
Disabled (default) | The system supports Non-Uniform Memory architecture (NUMA) (asymmetric) memory configurations. |
---|
Cluster On Die
Enable or Disable Cluster On Die (COD). Disabled is the default value.
Snoop Mode
Sets the snoop mode to maintain cache coherency across QPI. You can select the snoop mode as per the system configuration to optimize the system performance.
Early Snoop | Snoops are generated for local and remote requests. |
---|---|
Home Snoop | Multiple snoops are generated for different cache line addresses. |
Cluster-on-Die | Enhances the performance with two caching agents. |
Correctable Memory ECC SMI
Enable or disable Correctable Memory ECC SMI. Enabled is the default value.
