EnablingAMDPowerNow!™Technology

AMD PowerNow! technology controls your system's processor performance automatically, dynamically adjusting the operating frequency and voltage according
to the task at hand. When an application does not require full performance, significant amounts of power can be saved. Performance is designed to still be
responsive, with maximum processor performance being delivered when required, and automatic power savings when possible.
To disable the AMD PowerNow! feature, run the System Setup Program and disable the Demand-Based Power Management option on the CPU Information
screen.

Integrated Devices Screen
Option
Description
System Memory
Size
Displays the amount of system memory.
System Memory
Type
Displays the type of system memory.
System Memory
Speed
Displays the system memory speed.
Video Memory
Displays the amount of video memory.
System Memory
Testing
Specifies whether system memory tests are run at system boot. Options are Enabled and Disabled.
Redundant Memory
(Disabled default)
Enables or disables the redundant memory feature. When set to Spare Mode, the first rank of memory on each DIMM is reserved for
memory sparing. See Memory Sparing Support. Redundant memory feature is disabled if the Node Interleaving field is enabled.
Node Interleaving
If this field is enabled, memory interleaving is supported if a symmetric memory configuration is installed. If this field is set to disabled
(the default), the system can support Non-Uniform Memory architecture (NUMA) (asymmetric) memory configurations.
NOTE: The Node Interleaving field must be set to Disabled when using the redundant memory feature.
Memory Optimizer
Technology
(Enabled default)
Sets the behavior of the two DRAM controllers for memory optimization. When set to Enabled, the two controllers run in parallel 64-bit
mode for improved memory performance (running single-bit ECC).When set to Disabled, the controllers are joined in 128-bit mode
running multi-bit Advanced ECC.
Low Power Mode
(Disabled default)
Enables or disables the low power mode of the memory. When set to Disabled, the memory runs at full speed. When set to Enabled,
the memory runs at a reduced speed to conserve energy.
Option
Description
64-bit
Specifies if the installed processors support 64-bit extensions.
Core Speed
Displays the clock speed of the processors.
Bus Speed
Displays the bus speed of the processors.
Virtualization
Technology
(Enabled default)
NOTE: Disable this feature if your system will not be running virtualization software.
Displays when the processors support Virtualization Technology. Enabled permits virtualization software to use Virtualization
Technology incorporated in the processor design. This feature can only be used by software that supports Virtualization Technology.
Demand-Based
Power Management
(Enabled default)
NOTE: Check your operating system documentation to verify if the operating system supports this feature.
Enables or disables demand-based power management. When enabled, the CPU Performance State tables will be reported to the
operating system; when disabled, the CPU Performance State tables will not be reported to the operating system. If any of the CPUs
do not support demand-based power management, the field will become read-only, and automatically set to Disabled.
Processor X ID
Displays the family, model, and stepping of the specified processor.
