BIOS Setup D.O.T Mode This item allows you to decide the mode to overclock dynamically. Setting options: CPU Only, CPU+AGP. CPU Ratio Selection This setting controls the multiplier that is used to determine the internal clock speed of the processor relative to the external or motherboard clock speed. DRAM Frequency (Mhz) Use this field to configure the clock frequency of the installed DRAM. Settings are: PSB 400: 266, Auto, 333, 400, 433, 466, 500. PSB 533: 266, 333, Auto, 400, 433, 450, 466, 500, 354 (3:4). PSB 800: 266, 333, 400, Auto, 433, 450, 466, 500, 532, 501 (4:5), 533 (3:4). MSI Reminds You... The value plus a ratio (CPU: DDR) with parentheses means the non-synchronous overclocking. Spread Spectrum When the motherboard's clock generator pulses, the extreme values (spikes) of the pulses creates EMI (Electromagnetic Interference). The Spread Spectrum function reduces the EMI generated by modulating the pulses so that the spikes of the pulses are reduced to flatter curves. 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, activate the Spread Spectrum for EMI reduction. 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. Options: Disabled, Enabled. Adjust CPU Bus Clock (Mhz) This item allows you to select the CPU Bus clock frequency (in MHz) and overclock the processor by adjusting the FSB clock to a higher frequency. Settings are: PSB 400: 100-355MHz. PSB 533: 133-500MHz PSB 800: 200-500MHz 3-29
