SUPER MICRO Computer X8DTU-6TF+, X8DTU-6F+ MPS and Acpi Madt Ordering, Active Processor Cores

Chapter 5: AMI BIOS

MPS and ACPI MADT Ordering

This feature allows the user to configure the MPS (Multi-Processor Specifica- tions) and ACPI (Advanced Configuration and Power Interface) settings for your motherboard. Select Modern Ordering if XP or a newer version of Windows OS is used in the motherboard. Select Legacy Ordering if 2000 or an earlier version is used. The options are Modern Ordering and Legacy Ordering.

Intel® Virtualization Technology (Available when supported by the CPU)

Select Enabled to use the feature of Virtualization Technology to allow one platform to run multiple operating systems and applications in independent partitions, creat- ing multiple "virtual" systems in one physical computer. The options are Enabled and Disabled. Note: If there is any change to this setting, you will need to power off and restart the system for the change to take effect. Please refer to Intel’s web site for detailed information.

Execute-Disable Bit Capability (Available when supported by the OS and the CPU)

Set to Enabled to enable Execute Disable Bit support which will allow the proces- sor to designate areas in the system memory where an application code can be executed and where it cannot, thus preventing a worm or a virus from flooding illegal codes to overwhelm the processor or damage the system during an attack. The default is Enabled. (Refer to Intel and Microsoft Web Sites for more information.)

Intel AES-NI (Available when supported by the OS and the CPU)

It set to enabled, Intel AES-NI will add new encryption features to help accelerate AES SW application and provide code authorization and signature verification to improve system performance. The default is Disabled. (Refer to Intel and Microsoft Web Sites for more information.)

Simultaneous Multi-Threading (Available when supported by the CPU)

Set to Enabled to use the Simultaneous Multi-Threading Technology, which will result in increased CPU performance. The options are Disabled and Enabled.

Active Processor Cores

Set to Enabled to use a processor's Second Core and beyond. (Please refer to Intel's web site for more information.) The options are All, 1, 2, 3, 4, and 5.

Intel® EIST Technology

EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically adjust processor voltage and core frequency in an effort to reduce power consump- tion and heat dissipation. Please refer to Intel’s web site for detailed information. The options are Disabled (Disable GV3) and Enabled (Enable GV3).
