BIOS Setup
fGlobal C-state Control [Enabled] (optional)
Enables/ disables IO based C-state generation and DF C-states.
fSimultaneous Multi-Threading [Enabled] (optional)
Enables/ disables the AMD Simultaneous Multi-Threading. This item appears when
the installed CPU supports this technology.
fOpcache Control [Auto] (optional)
Enables/ disables Opcache. Opcache stores recent decode instruction to save
the decoding time when the instruction is repeated. And it may increase the CPU
performance and reduce the power consumption slightly.
fIOMMU Mode (optional)
Enables/disables the IOMMU (I/O Memory Management Unit) for I/O Virtualization.
fSpread Spectrum (optional)
This function reduces the EMI (Electromagnetic Interference) generated by
modulating clock generator pulses.
[Enabled] Enables the spread spectrum function to reduce the EMI
(Electromagnetic Interference) problem.
[Disabled] Enhances the overclocking ability of CPU Base clock.
Important
y
If you do not have any EMI problem, leave the setting at [Disabled] for optimal system
stability and performance. But if you are plagued by EMI, select the value of Spread
Spectrum for EMI reduction.
y
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.
y
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.
fRelaxed EDC throttling [Auto] (optional)
Relaxed EDC throttling reduces the amount of time the processor will throttle the
cores.
[Auto] AMD's recommendation
[Enabled] Reduce the amount of time the processor will throttle.
[Disabled] Part-specific EDC throttling protection enabled.
fAMD Cool’n’Quiet [Enabled]
The Cool’n’Quiet technology can effectively and dynamically lower CPU speed and
power consumption.
fSVM Mode [Enabled]
Enables/ disables the AMD SVM (Secure Virtual Machine) Mode.
