Thermal Management
The processor used has a thermal monitor. In order to maintain real-time it is switched off.
Limit CPUID MaxVal
This option supports Prescott CPUs in older operating systems. Enabled: Activate this option if an older operating
system is used. Disabled: Deactivate the CPUID limit if Windows XP is used.
C1E Function
This option is only available for certain processors with C1E (Enhanced Halt State) function.
CPU C State Capability
This option can be used to set the lowest C-state of the CPU. Usually DISABLED should be selected.
DISABLED: function off
C2 (STOP Grant): CPU clock is stopped, API functions run with normal speed
C4 (Deeper Sleep): CPU voltage is reduced.
C6 (Deep Power Down): CPU voltage is reduced to 0 V.
Execute Disable Bit
This option represents a safety function that can help you to protect your CPU and your operating system from
malicious software that may execute a code and harm the BIOS. This option is available only if the CPU supports this
function. Setting options: Enabled, Disabled.
Virtualization Technology
This option activates or deactivates the additional hardware capabilities of virtualization technology. Intel
Virtualization Technology (code names Vanderpool or Vanderpool Technology) describes the implementation of a
Secure Virtual Machine by Intel. AMD Virtualization or AMD-V (also known under the code name "Pacifica") is a
technology for virtualization of a computer and refers to AMD's implementation of a Secure Virtual Machine in
conjunction with an IOMMU. Setting options: Enabled, Disabled.
