the greater the Spread Spectrum value is, the greater the eMi is reduced, and
the system will become less stable. For the most suitable Spread Spectrum
value, please consult your local eMi regulation.
remember to disable Spread Spectrum if you are overclocking because even a
slight jitter can introduce a temporary boost in clock speed which may just cause
your overclocked processor to lock up.
drAM Voltage
this item is used to adjust the memory voltage.
CPu Features
Press <enter> to enter the sub-menu. in this sub-menu you can adjust the CPu
features.
Hyper-threading
the processor uses Hyper-threading technology to increase transaction rates
and reduces end-user response times. the technology treats the two cores
inside the processor as two logical processors that can execute instructions
simultaneously. in this way, the system performance is highly improved. if you
disable the function, the processor will use only one core to execute the in-
structions. Please disable this item if your operating system doesn’t support Ht
Function, or unreliability and instability may occur.
Active Processor Cores
this item allows you to select the number of active processor cores.
Limit CPuid Maximum
it is designed to limit the listed speed of the processor to older operating sys-
tems.
execute disable Bit
Can prevent certain classes of malicious “buffer overflow” attacks where worms
can try to execute code to damage your system. it is recommended you keep
this enabled always.
intel Virtualization tech
enhances virtualization and allows the system to act as multiple virtual sys-
tems. 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 infor-
mation please refer to intel’s official website.
Power technology
this item allows you to select the intel dynamic Power technology mode.
Ce Support
enable system to reduce CPu power consumption while idle. Not all processors
support enhanced Halt state (Ce).
overSpeed Protection
Monitors current CPu draw as well as power consumption; if it exceeds a cer-
tain level, the processor automatically reduces its clock speed. For overclock-
ing, it is recommended this feature is disabled.
