BIOS.MemSettings.LockState23 (Read or Write) Description The security state of this NVDIMM as unknown, disabled, unlocked, locked, frozen, max password, and not supported. Legal Values ● Unknown ● Disabled ● Unlocked ● Locked ● Frozen ● NotSupported Default Value Not Applicable Write Privilege Server Control License Required iDRAC Express or iDRAC Enterprise Dependency Not applicable BIOS.MemSettings.MemLowPower (Read or Write) Description Enables or disables the low-power mode of memory. When set to Disabled, the memory will run at full speed. When set to Enabled, the memory will run at a reduced speed to conserve power. Default: Disabled Not used on 13G+. Legal Values ● Enabled ● Disabled Default Value Not Applicable Write Privilege Server Control License Required iDRAC Express or iDRAC Enterprise Dependency Not applicable BIOS.MemSettings.MemOpMode (Read or Write) Description Allows the selection of the memory operating mode. Certain options are active only if a valid memory configuration is detected. When the Optimizer Mode is enabled, the DRAM controllers operate independently in 64-bit mode and provide optimized memory performance. When Advanced ECC Mode is enabled, 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 Operating System. When Mirror Mode is enabled, the system maintains two identical copies of data in the memory. This feature provides maximum reliability and enables the system to continue running even during a high severity memory failure. NOTE: In Mirror Mode, only half of the installed system memory is reported to the operating system. When Spare Mode is enabled, the BIOS reserves a rank of memory as a spare. At runtime, the memory controller can move a rank that exhibits a large number of correctable errors to the spare rank. NOTE: In Spare Mode, the system memory size reported to the Operating System does not include the spare portion. Spare with Advanced ECC Mode operates similarly to the Spare Mode. When this mode is enabled, the system runs under Advanced ECC mode with a spare rank reserved in each channel. NOTE: In Spare with Advanced ECC Mode, the system memory size reported to the Operating System does not include the spare portion. When Dell Fault Resilient Mode is enabled, the BIOS 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. Default: Optimizer Mode For FRM, need platform to support Mirror mode. For NUMA FRM, need to have 2 CPU installed + platform support Mirror mode. [MirrorMode, Lockstep] Needs identical memory configurations in channles behind each memory controller. 188 BIOS Attributes
