The following table describes the features of the Advanced PCI Configuration screen.
Table 9. Advanced PCI Configuration Details
System Acoustics and Performance Configuration
The System Acoustic and Performance Configuration screen allows the user to configure
the DIMM thermal management option for the Intel® Compute Module MFS5520VI.
Specifically the System Acoustics and Performance Configuration screen allows the user
to set the DIMM throttling mode to Auto (default), Static Closed Loop Thermal Throttling
(CLTT) or Static Open Loop Thermal Throttling (OLTT). By default this field is set to
Auto. When set to Auto the BIOS will configure the system for Static Closed Loop
Thermal Throttling (CLTT) as long as the installed DIMMs have Module Thermal
Sensors. With the Throttling mode set to CLTT the system is able to accurately control
memory temperatures, which is necessary to manage system performance within thermal
parameters.To set the throttling mode, select one of the following configuration options:
•
[Auto] – Auto Throttling mode
•
[CLTT] – Closed Loop Thermal Throttling Mode
•
[OLTT] – Open Loop Thermal Throttling Mode
Notes: The OLTT option is shown for informational purposes only. If the user selects OLTT, the
BIOS overrides that selection if the system can support CLTT. OLTT is configured only
when unbuffered DIMMs
To access this screen from the Main screen press the right arrow key until the Advanced
menu is selected then press the down or up arrow key to highlight System Acoustics and
Performance Configuration and press <Enter>.

If enabled, BIOS maximizes usage of memory
below 4 GB for an OS without PAE by limiting
PCIe* Extended Configuration Space to 64
buses.
Enable or disable memory mapped I/O of 64-bit
PCI devices to 4 GB or greater address space.
Load the embedded option ROM for the
onboard network controllers.
Warning: If [Disabled] is selected, NIC1 cannot
be used to boot or wake the system.
