MS-7530 Mainboard DRAM Voltage (V) Adjusting the memory voltage can increase the memory speed. NB Voltage (V) Adjust the North Bridge chipset voltage. VTT FSB Voltage (V) This item allows you to set the FSB VTT voltage. CPU/LDT Spread Spectrum This setting is used to enable or disable the CPU Spread Spectrum feature. W hen overclocking the CPU, always set it to [Disabled]. iGPU Spread Spectrum This setting is used to set the internal GPU spread spectrum. W hen overclocking, please set it lower. SATA Spread Spectrum This setting is used to enable or disable the SATA Spread Spectrum feature. W hen overclocking, always set it to [Disabled]. Important 1. 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. 2. 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. 3. 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. 3-22

select the value of Spread Spectrum for EMI reduction.
2. 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.
3. 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.
