Frequency/Voltage Control The items in this submenu includes some important settings of CPU, AGP, DRAM and overclocking functions. MSI Reminds You... Change these settings only if you are familiar with the chipset. Current FSB Frequency It shows the current clock frequency of the front side bus. (read only) Adjust CPU Ratio 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. Adjust CPU/AGP/PCI Frequency This setting allows you to select the clock frequency of CPU/AGP/PCI. Memory Voltage Adjusting the DDR voltage can increase the DDR speed. Any changes made to this setting may cause a stability issue, so changing the DDR voltage for long-term purpose is NOT recommended. AGP Voltage AGP voltage is adjustable in the field, allowing you to increase the performance of your AGP display card when overclocking, but the stability may be affected. Auto Disable DIMM/PCI Clock This item is used to auto detect the DIMM/PCI slots. When set to [Enabled], the system will remove (turn off) clocks from empty DIMM/PCI slots to minimize the electromagnetic interference (EMI). 14

Frequency/Voltage Control
The items in this submenu includes some important settings of CPU, AGP, DRAM and
overclocking functions.
MSI Reminds You...
Change these settings only if you are familiar with the chipset.
Current FSB Frequency
It shows the current clock frequency of the front side bus. (read only)
Adjust CPU Ratio
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.
Adjust CPU/AGP/PCI Frequency
This setting allows you to select the clock frequency of CPU/AGP/PCI.
Memory Voltage
Adjusting the DDR voltage can increase the DDR speed. Any changes made to this setting
may cause a stability issue, so changing the DDR voltage for long-term purpose is NOT
recommended.
AGP Voltage
AGP voltage is adjustable in the field, allowing you to increase the performance of your AGP
display card when overclocking, but the stability may be affected.
Auto Disable DIMM/PCI Clock
This item is used to auto detect the DIMM/PCI slots. When set to [Enabled], the system will
remove (turn off) clocks from empty DIMM/PCI slots to minimize the electromagnetic interference
(EMI).
