The following table describes the features of the Advanced PCI Configuration screen. Table 9. Advanced PCI Configuration Details Setup Item Maximize Memory below 4GB Options Enabled Disabled Memory Mapped I/O above 4GB Onboard NIC1 ROM Enabled Disabled Enabled Disabled Onboard NIC2 Enabled ROM Disabled NIC 1 MAC Address NIC 2 MAC Address Help Text 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. Load the embedded option ROM for the onboard network controllers. Warning: If [Disabled] is selected, NIC2 cannot be used to boot or wake the system Information only. 12 hex digits of the MAC address Information only. 12 hex digits of the MAC address. 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 (UDIMMs)UDIMMs without Thermal Sensors are installed. 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 . 72 Intel® Compute Module MFS5520VI User Guide
