Frequency Control Option - PCchips M757MR Manual

Frequency Control Option

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
When this item is enabled, BIOS will disabled the clock signal of free DIMM and
PCI slots.
Spread Spectrum
If you enable spread spectrum, it can significantly reduce the EMI (Electro-
Magnetic Interference) generated by the system.
CPU Host/SDRAM/PCI Clock
CPU Clock Ratio Jumpless
Use the CPU Host/SDRAM/PCI Clock to set the system bus frequency for the
installed processor (usually 100 MHz or 66 MHz). Then use CPU Clock Ratio to
set a multiple. The multiple times the system bus must equal the core speed of
the installed processor e.g. 3.5 (multiple) x 100 MHz (system bus) = 350 MHz
(installed processor clock speed). We recommend that you leave these items
to there default values Default and H/W (Hardware defined)
