3.9 Frequency/Voltage Control
This item allows you to set the clock speed and system bus for your system.
The clock speed and system bus are determined by the kind of processor you
have installed in your system.
Auto Detect DIMM/PCI Clk
D
efault: Enabled
When this item is enabled, the BIOS will disable the clock generator signal for
unused DIMM and PCI slots, in order to reduce EMI (electromagnetic
intererence).
Spread Spectrum
D
efault: Disabled
When this item is enabled, it can significantly reduce the EMI
(electromagnetic interference) that your system generates by modulating the
extreme values of the clock generator pulses. Enabling this item might cause
problems with timing-critical devices such as SCSI adapters. We recommend
that you leave this item at the default value disabled.
CPU Host/PCI Clock
D
efault: Default
Use this item to set the clock frequency speed for the CPU and PCI bus.
