AMD Phenom(tm) II X4 Processor Clear CMOS data. The CPU does not support CPU core unlock, please leave the default settngs for system. AMD Sempron(tm) II X2 Processor Important Ths CPU core unlocked behavor depends on the CPU ablty/ characterstc, and t s not guaranteed.

• En-30 MS-7640 Manboard Depend on CPU’s characterstc, once you get nstable scenaro, please restore the default settngs for system. You can also check the core numbers n performance tab of Wndows task manager. OC Gene Lte Settng ths tem to [Enabled] allows the system to detect the maxmum FSB clock and to overclock automatcally. If overclockng fals to run, you can try the lower FSB clock for overclockng successfully. Spread Spectrum When the manboard’s clock generator pulses, the extreme values (spkes) of the pulses create EMI (Electromagnetc Interference). The Spread Spectrum functon reduces the EMI generated by modulatng the pulses so that the spkes of the pulses are reduced to 󰘱atter curves. Important If you do not have any EMI problem, leave the settng at [Dsabled] for optmal system stablty and performance. But f you are plagued by EMI, select the value of Spread Spectrum for EMI reducton. The greater the Spread Spectrum value s, the greater the EMI s reduced, and the system wll become less stable. For the most sutable Spread Spectrum value, please consult your local EMI regulaton. Remember to dsable Spread Spectrum f you are overclockng because even a slght jtter can ntroduce a temporary boost n clock speed whch may just cause your overclocked processor to lock up.
