MSI ms-6382 manual Frequency/Voltage Control, Auto Detect PCI/DIMM Clk, Spread Spectrum

Chapter 3

Frequency/Voltage Control

This section describes how to set the Chassis Intrusion feature, CPU FSB frequency, monitor the current hardware status including CPU/system temperatures, CPU/System Fan speeds, Vcore etc. Monitor function is avail- able only if there is hardware monitoring mechanism onboard.

Auto Detect PCI/DIMM Clk

This option allows you to enable/disable the feature of auto detecting the clock frequency of DIMM and PCI bus. The settings are: Enabled, Disabled.

Spread Spectrum

When the motherboard’s clock generator pulses, the extreme values (spikes) of the pulses creates EMI (Electromagnetic Interference). The Spread Spec- trum 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, change the setting for EMI reduction. Remember to disable Spread Spectrum if you are overclocking be- cause even a slight jitter can introduce a temporary boost in clockspeed which may just cause your overclocked processor to lock up. Options: Disabled, -1.50%, -1.00%, -0.70%, -0.50%, +/-0.25%, +/-0.35%, +/-0.50%, +/-0.75%.

CPU/PCI Clock

This setting controls the clock frequency of the CPU/PCI bus on the motherboard. Options: Default.
