Cool ‘n’ Quiet

Use this item to enable or disable AMD’s Cool ‘n’ QuietTM technology. The default value is [Enabled]. Configuration options: [Enabled] and [Disabled]. If you install Windows® 7 / VistaTM and want to enable this function, please set this item to [Enabled]. Please note that enabling this function may re- duce CPU voltage and memory frequency, and lead to system stability or compatibility issue with some memory modules or power supplies. Please set this item to [Disable] if above issue occurs.

Secure Virtual Machine

When this option is set to [Enabled], a VMM (Virtual Machine Architecture) can utilize the additional hardware capabilities provided by AMD-V. The default value is [Enabled]. Configuration options: [Enabled] and [Disabled].

Enhance Halt State (C1E)

All processors support the Halt State (C1). The C1 state is supported through the native processor instructions HLT and MWAIT and requires no hardware support from the chipset. In the C1 power state, the processor maintains the context of the system caches.

CPU Thermal Throttle

Use this item to enable CPU internal thermal control mechanism to keep the CPU from overheated. The default value is [Auto].
