BIOS Setup ▶ Intel Virtualization Tech Enhances virtualization and allows the system to act as multiple virtual systems. See Intel's official website for more information. ▶ Intel VT-D Tech This item is used to enable/disable the Intel VT-D technology. For further information please refer to Intel's official website. ▶ Power Technology This item allows you to select the Intel Dynamic Power technology mode. ▶ C1E Support Enable system to reduce CPU power consumption while idle. Not all processors support Enhanced Halt state (C1E). ▶ OverSpeed Protection Monitors current CPU draw as well as power consumption; if it exceeds a certain level, the processor automatically reduces its clock speed. For overclocking, it is recommended this feature is disabled. ▶ Intel C-State C-state is a power management state that detects when the system is idle and lowers power consumption accordingly. ▶ Package C State limit This field allows you to select a C-state mode. ▶ Long duration power limit (W) This field allows you to adjust the TDP power limit for the long duration. ▶ Long duration maintained (s) This field allows you to adjust the maintaining time for long duration power limit. ▶ Short duration power limit (W) This field allows you to adjust the TDP power limit for the short duration. ▶ Primary/ Secondary Plane Current value These fields allow you to adjust over current value of CPU (primary plane)/ iGPU (secondary plane) for turbo ratio. ▶ Primary/ Secondary plane turbo power limit (W) These fields allow you to adjust the turbo power limit of CPU (primary plane)/ iGPU (secondary plane) for turbo boost. 2-14

BIOS Setup
Intel V±rtual±zat±on Tech
Enhances v±rtual±zat±on and allows the system to act as mult±ple v±rtual systems. See
Intel’s offic±al webs±te for more ±nformat±on.
Intel VT-D Tech
Th±s ±tem ±s used to enable/d±sable the Intel VT-D technology. For further ±nformat±on
please refer to Intel’s offic±al webs±te.
Power Technology
Th±s ±tem allows you to select the Intel Dynam±c Power technology mode.
C1E Support
Enable system to reduce CPU power consumpt±on wh±le ±dle. Not all processors
support Enhanced Halt state (C1E).
OverSpeed Protect±on
Mon±tors current CPU draw as well as power consumpt±on; ±f ±t exceeds a certa±n
level, the processor automat±cally reduces ±ts clock speed. For overclock±ng, ±t ±s
recommended th±s feature ±s d±sabled.
Intel C-State
C-state ±s a power management state that detects when the system ±s ±dle and
lowers power consumpt±on accord±ngly.
Package C State l±m±t
Th±s field allows you to select a C-state mode.
Long durat±on power l±m±t (W)
Th±s field allows you to adjust the TDP power l±m±t for the long durat±on.
Long durat±on ma±nta±ned (s)
Th±s field allows you to adjust the ma±nta±n±ng t±me for long durat±on power l±m±t.
Short durat±on power l±m±t (W)
Th±s field allows you to adjust the TDP power l±m±t for the short durat±on.
Pr±mary/ Secondary Plane Current value
These fields allow you to adjust over current value of CPU (pr±mary plane)/ ±GPU
(secondary plane) for turbo rat±o.
Pr±mary/ Secondary plane turbo power l±m±t (W)
These fields allow you to adjust the turbo power l±m±t of CPU (pr±mary plane)/ ±GPU
(secondary plane) for turbo boost.
