Should I enable spread spectrum in BIOS?
Should I enable spread spectrum in BIOS?
The MCLK Spread Spectrum BIOS feature controls spread spectrum clocking of the memory bus. However, system stability may be compromised if you are overclocking the memory bus. Therefore, it is recommended that you disable the MCLK Spread Spectrum feature if you are overclocking the memory bus.
What is Spread Spectrum oscillator?
Spread-Spectrum Crystal Oscillators (SSXO) are oscillators whose output frequency differs in a narrow range around the desired clock rate and produces a wider spectrum of output frequencies with spectral lines as compared to a conventional single tone.
How does a MEMS oscillator work?
MEMS oscillator suppliers solve the diversity problem by leveraging circuit technology. While quartz oscillators are usually built with the quartz crystals driven at the desired output frequencies, MEMS oscillators commonly drive the resonators at one frequency and multiply this to the designed output frequency.
What is PCIE spread spectrum clocking?
Spread spectrum clocking is the process by which the system clock is dithered in a controlled manner so as to reduce peak energy content. SSC techniques are used so as to minimize Electromagnetic Interference (EMI) and/or pass Federal Communications Commission (FCC) requirements.
Should I disable PCIE spread spectrum?
If you are using such devices on the PCI Express interconnect, you must disable PCIE Spread Spectrum. System stability may also be compromised if you are overclocking the PCI Express interconnect. Therefore, it is recommended that you disable this feature if you are overclocking the PCI Express interconnect.
Can I disable Spread Spectrum?
There’s really no point in disabling spread spectrum, if you are unstable with it on, you are gonna continue being unable with it also off…
Why is spread spectrum needed?
The main advantage of spread spectrum communication technique is to prevent “interference” whether it is intentional or unintentional. The signals modulated with these techniques are hard to interfere and cannot be jammed. These spread spectrum signals transmit at low power density and has a wide spread of signals.
Why is spread spectrum used?
Spread Spectrum refers to a system originally developed for military applications, to provide secure communications by spreading the signal over a large frequency band. These narrowband signals are easily jammed by any other signal in the same band.
What is the difference between resonator and oscillator?
A resonator is a device which exhibits resonance or resonant behavior. An oscillator is a electronic device which produces periodic oscillating electronic signal.
What is PCIe spread spectrum in BIOS?
The PCIE Spread Spectrum BIOS feature controls spread spectrum clocking of the PCI Express interconnect. When set to Down Spread, the motherboard modulates the PCI Express interconnect’s clock signal downwards by a small amount. Generally, frequency modulation via this feature should not cause any problems.
