fSimultaneous Multi-Threading [Enabled] (optional)
Enables/ disables the AMD Simultaneous Multi-Threading. This item appears when
the installed CPU supports this technology.
fGlobal C-state Control [Enabled] (optional)
Enables/ disables IO based C-state generation and DF C-states.
fOpcache Control [Auto] (optional)
Enables/ disables Opcache. Opcache stores recently decode instruction to save
the decoding time when the instruction is repeated. And ist 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
If you do not have any EMI problem, leave the setting at [Disabled] for optimal system
y
stability and performance. But if you are plagued by EMI, select the value of Spread
Spectrum for EMI reduction.
The greater the Spread Spectrum value is, the greater the EMI is reduced, and the
y
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
y
slight jitter can introduce a temporary boost in clock speed which may just cause your
overclocked processor to lock up.
