Frequency/Voltage Control - MSI MS-7095 Instruction Manual

Frequency/Voltage Control

CPU Clock Ratio
End users can overclock the processor (only if the processor supports so) by specifying the CPU
ratio (clock multiplier) in this field.
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. Setting options: 1.5V to 1.8V at
0.05V increment.
Auto Disable DIMM/PCI Clock
This item is used to auto detect the PCI slots. When set to Enabled, the system will remove (turn
off) clocks from empty PCI slots to minimize the electromagnetic interference (EMI).
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, set to Enabled 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.
CPU Host/AGP/PCI Clock
Use this item to select the appropriate clock frequency of the CPU host/AGP/PCI bus.
