Advanced Memory Configuration Screen Details Setup Item Total Memory Effective Memory Current Configuration Current Memory Speed Memory RAS and Performance Configuration DIMM_ XY Options Description Information only. The amount of memory available in the system in the form of installed DIMMs, in units of MB or GB. Information only. The amount of memory available to the OS in MB or GB. The Effective Memory is the difference between the Total Physical Memory and the sum of all memory reserved for internal usage, RAS redundancy and SMRAM. This difference includes the sum of all DIMMs that failed Memory BIST during POST or were disabled by the BIOS during the memory discovery phase in order to optimize memory configuration. Information only. Displays one of the following: • Independent Mode: System memory is configured for optimal performance and efficiency and no RAS is enabled. • Mirror Mode: System memory is configured for maximum reliability in the form of memory mirroring. Information only. Displays the speed at which the memory is running. Select to configure memory RAS (Reliability, Availability, and Serviceability) and view current memory performance information and settings. This takes the user to a different screen. Displays the state of each DIMM socket present on the board. Each DIMM socket field reflects one of the following possible states: • Installed: There is a DIMM installed in this slot. • Not Installed: There is no DIMM installed in this slot. • Disabled: The DIMM installed in this slot has been disabled by the BIOS in order to optimize memory configuration. • Failed: The DIMM installed in this slot is faulty / malfunctioning. Note: X denotes the Channel Identifier and Y denotes the DIMM Identifier within the Channel. Memory RAS and Performance Configuration The Memory RAS (Reliability, Availability, and Serviceability) and Performance Configuration screen displays current memory performance information and settings. Under capabilities, this screen displays whether memory mirroring is possible (Yes / No) and allows the user to enable or disable NUMA optimization. Intel® Compute Module MFS5520VI User Guide 65

The following table describes the features of the Advanced Memory Configuration screen.
Memory RAS and Performance Configuration
The Memory RAS (Reliability, Availability, and Serviceability) and Performance
Configuration screen displays current memory performance information and settings.
Under capabilities, this screen displays whether memory mirroring is possible (Yes / No)
and allows the user to enable or disable NUMA optimization.
Table 7. Advanced Memory Configuration Screen Details
Setup Item
Options
Description
Total Memory
Information only
. The amount of memory available in
the system in the form of installed DIMMs, in units of MB
or GB.
Effective
Memory
Information only
. The amount of memory available to
the OS in MB or GB.
The Effective Memory is the difference between the
Total Physical Memory and the sum of all memory
reserved for internal usage, RAS redundancy and
SMRAM. This difference includes the sum of all DIMMs
that failed Memory BIST during POST or were disabled
by the BIOS during the memory discovery phase in
order to optimize memory configuration.
Current
Configuration
Information only
. Displays one of the following:
•
Independent Mode
: System memory is configured
for optimal performance and efficiency and no RAS
is enabled.
•
Mirror Mode
: System memory is configured for
maximum reliability in the form of memory
mirroring.
Current
Memory Speed
I
nformation only
. Displays the speed at which the
memory is running.
Memory RAS
and
Performance
Configuration
Select to configure memory RAS (Reliability, Availability,
and Serviceability) and view current memory
performance information and settings. This takes the
user to a different screen.
DIMM_ XY
Displays the state of each DIMM socket present on the
board. Each DIMM socket field reflects one of the
following possible states:
•
I
nstalled
: There is a DIMM installed in this slot.
•
Not Installed
: There is no DIMM installed in this
slot.
•
Disabled:
The DIMM installed in this slot has been
disabled by the BIOS in order to optimize memory
configuration.
•
Failed
: The DIMM installed in this slot is faulty /
malfunctioning.
Note
: X denotes the Channel Identifier and Y denotes
the DIMM Identifier within the Channel.
