Gigabyte GA-990FX - CPU Power Management and XMP; Advanced Memory Settings

& Core C6 State
(Note 1)
Allows you to determine whether to let the CPU enter C6 mode in system halt state. When enabled, the
CPU core frequency will be reduced during system halt state to decrease power consumption. The C6
stateisamoreenhancedpower-savingstatethanC1.(Default:Enabled)
& HPC Mode
(Note 1)
Allows you to determine whether to enable High Performance Computing (HPC) mode for the CPU. Enabled
preventstheCPUfrequencyfrombeingloweredduringsystemhaltstate.(Default:Disabled)
& APM (AMD Application Power Management)
(Note 1)
Enabled  Dynamicallymonitors the power consumption of theCPU cores and automatically
optimizestheCPUtoitsbestperformancelevel.(Default)
Disabled  Disablesthisfunction.
& ExtremeMemoryProle(X.M.P.)
(Note 2)
 AllowstheBIOStoreadtheSPDdataonXMPmemorymodule(s)toenhancememoryperformancewhen
enabled.
Disabled  Disablesthisfunction.(Default)
Prole1  UsesProle1settings.
Prole2
(Note 2)
 UsesProle2settings.
& System Memory Multiplier
Allows you to set the system memory multiplier. AutosetsmemorymultiplieraccordingtomemorySPD
data.(Default:Auto)
& Memory Frequency (MHz)
This value is automatically adjusted according to the BCLK Clock Control and System Memory Multiplier
settings.

& ProleDDRVoltage
When using a non-XMP memory module or ExtremeMemoryProle(X.M.P.) is set to Disabled, the value
isdisplayedaccordingtoyourmemoryspecication.WhenExtremeMemoryProle(X.M.P.) is set to
Prole1 or Prole2,thevalueisdisplayedaccordingtotheSPDdataontheXMPmemory.
& ProleVTTVoltage
The value displayed here is dependent on the CPU being used.
& Channel Interleaving
Enables or disables memory channel interleaving. Enabled allows the system to simultaneously access
different channels of the memory to increase memory performance and stability. Auto lets the BIOS
automaticallycongurethissetting.(Default:Auto)
& Rank Interleaving
Enables or disables memory rank interleaving. Enabled allows the system to simultaneously access different
ranks of the memory to increase memory performance and stability. Auto lets the BIOS automatically
congurethissetting.(Default:Auto)
