Thermal Management 2
1
Set to Enabled to use thermal management 2 (TM2), which lowers CPU
voltage and frequency when the CPU temperature reaches a predefined
overheat threshold. Set to Disabled to use thermal management 1 (TM1),
which regulates CPU clocking via CPU internal clock modulation when the
CPU temperature reaches the overheat threshold. The options are Disabled
and Enabled (default).
Adjacent Cache Line Prefetch
1
The CPU fetches the cache line for 64 bytes if this option is set to Disabled.
The CPU fetches both cache lines for 128 bytes as comprised if set to
Enabled. The options are Disabled and Enabled (default).
C1 Enhanced Mode
1
Set to Enabled to enable Enhanced Halt State, which lowers CPU
voltage/frequency to prevent overheating. The options are Enabled and
Disabled (default).
Note Refer to the Intel Web site for detailed information.
Intel Virtualization Technology
1
Set to Enabled to use virtualization technology, which allows one platform
to run multiple operating systems and applications in independent
partitions, creating multiple “virtual” systems on one physical computer.
The options are Enabled and Disabled (default).
Note When changing this setting, you must power off and restart the system for the
change to take effect. Refer to the Intel Web site for detailed information.
No Execute Mode Memory Protection
2
Set to Enabled to enable Execute Disable Bit, which allows the processor
to classify areas in memory where an application code can execute and
where it cannot. This prevents a worm or virus from creating a flood of
codes to overwhelm the processor or damage the system during an attack.
The options are Disabled and Enabled (default).
1
