Jul 25, 2001  Spread Spectrum Control: This function is used for meeting the specifications when complying with the CE acceptance test. Enabling it leads toWhat is clock spread spectrum in the BIOS settings? A computers clock is an electronic signal that goes up and then goes down at a particular rate (frequency) and controls and synchronizes the operation of the CPU and motherboard. It is essential bios cpu clock spread spectrum

Jun 18, 2017  The MCLK Spread Spectrum BIOS feature controls spread spectrum clocking of the memory bus. It usually offers three levels of modulation 0. 25, 0. 5 or 0. 75. They denote the amount of modulation around the memory bus frequency. The

Sep 08, 2005 Remember to disable Spread Spectrum if you are overclocking because even a 0. 25 jitter can introduce a temporary boost in clockspeed of 25MHz (with a 1GHz CPU) which may just cause your overclocked processor to lock up. Or at least use the Smart Clock setting as that doesn't involve any modulation of the frequency.

Sep 22, 2016 Hi there. I want to disable the spread spectrum feature but i don't find it in my bios, and as the title says does it has some other name? Thanks.

Some BIOSes also offer a Smart Clock option. This works differently from spread spectrum clocking, although it is usually offered as an option under the Spread Spectrum BIOS feature. Instead of modulating the frequency of clock signals over time, Smart Clock turns off the PCI Express (or AGP), PCI and memory clock signals that are not in use.

Jan 15, 2006 SO WHAT GOOD IS SPREAD SPECTRUM? Spread spectrum is a trick used to allow products to pass FCC testing. Inside almost every electronic device is an oscillator of some sort. On a typical motherboard, the frontsidebus may operate at 200MHz. This means that there is a steady 200MHz clock which is running all of the time. This clock runs over

Which is just about the most definitive bios guide i've found so far. Always worth a look for any bios related enquiries. Spread Spectrum Options: Enabled, Disabled, 0. 25, 0. 5, Smart Clock When the motherboard's clock generator pulses, the extreme values (spikes) of the pulses creates EMI (Electromagnetic Interference).

Spread spectrum clocking works by continuously modulating the clock signal around a particular frequency. This spreads out the power output and flattens the spikes of signal waveform, keeping them below the FCC limit. This BIOS feature controls spread spectrum clocking of the processor's front side bus (also known as the FSB or processor bus).
