Comments: Information only. Displays whether the current DIMM configuration is capable of
Memory Lockstep. For Memory Lockstep to be possible, DIMM configurations on all paired channels
must be identical between the channel pair.

4. Select Memory RAS Configuration
Option Values: Maximum Performance
Mirroring
Rank Sparing
Lockstep
Help Text:
Allows the user to select the memory RAS Configuration to be applied for the next boot.
Comments: Available modes depend on the current memory population. Modes which are not
listed as “possible” should not be available as choices. If the only valid choice is “Maximum
Performance”, then this option should be grayed out and unavailable.
Maximum Performance(default) no RAS, but best memory utilization since full amount of
memory is available, operating in Independent Channel Mode.
Mirroring - most reliability by using half of memory as a mirror image, can survive an
Uncorrectable ECC Error.
Rank Sparingoffers reliability by reserving spare ranks to replace failing ranks which are
generating excessive Correctable ECC Errors.
Lockstepallows SDDC capability with x8 DIMMs installed. No memory size impact, but does
have a performance and power penalty.
Note: since only RAS Modes which are listed as “possible” are available for selection, it is not possible
to select a RAS Mode without first installing an appropriate DIMM configuration.

5. NUMA Optimized
Option Values: Enabled
Disabled
Help Text:
If enabled, BIOS includes ACPI tables that are required for NUMA-aware Operating Systems.
Comments: This option is only present for boards which have two or more processor sockets.
When a multi-socket board has only a single processor installed, this option is grayed out and set as
Disabled.
When enabled, the SRAT and SLIT ACPI tables are provided that show the locality of systems
resources, especially memory, which allows a “NUMA Aware” OS to optimize which processor threads
are used by processes which can benefit by having the best access to those resources.

Mass Storage Controller Configuration
The Mass Storage Configuration screen allows the user to configure the Mass Storage controllers that are
integrated into the server board on which the BIOS is executing. This includes only onboard Mass Storage
controllers. Mass Storage controllers on add-in cards are not included in this screen, nor are other storage
mechanisms such as USB-attached storage devices or Network Attached Storage.
