Super X13DSF-A User's Manual
DCU Streamer Prefetcher
If this feature is set to Enable, the Data Cache Unit (DCU) streamer prefetcher will prefetch
data streams from the cache memory to the DCU to speed up data accessing and processing
to enhance CPU performance. The options are Enable and Disable.
DCU IP Prefetcher
This feature allows the system to use the sequential load history, which is based on the
instruction pointer of previous loads, to determine whether the system will prefetch additional
lines. The options are Enable and Disable.
LLC Prefetch
If this feature is set to Enable, LLC (hardware cache) prefetching on all threads will be
supported. The options are Disable and Enable.
Extended APIC
Based on the Intel Hyper-Threading technology, each logical processor (thread) is assigned
256 APIC IDs (APIDs) in 8-bit bandwidth. When this feature is set to Enable, the APIC ID
will be expanded from 8 bits to 16 bits to provide 512 APIDs to each thread to enhance CPU
performance. The options are Disable and Enable. (APIC is the abbreviation for Extended
Advanced Programmable Interrupt Controller.)
Intel Virtualization Technology
Select Enable to enable the Intel Vanderpool Technology for Virtualization platform support,
which will allow multiple operating systems to run simultaneously on the same computer to
maximize system resources for performance enhancement. The options are Disable and
Enable.
Note: Please reboot the system for any change of the setting to take effect.
Enable SMX
Select Enable to support Safer Mode Extensions (SMX) which provides a programming
interface for system software to establish a controlled environment to support the trusted
platform configured by the end user and to verify a virtual machine monitor before it is allowed
to run. The options are Disable and Enable.
PPIN Control
Select Unlock/Enable to use the Protected Processor Inventory Number (PPIN) in the system.
The PPIN is a unique number set for tracking a given Intel Xeon server processor. The options
are Lock/Disable and Unlock/Enable.
AES-NI
Select Enable to use the Intel Advanced Encryption Standard (AES) New Instructions (NI) to
ensure data security. The options are Disable and Enable.
