Select the host clock of your Socket 370 processor among these values.

Note: For the Via 694X chipset, 66 and 100 and 133 MHz host clock frequencies are acceptable. However, the system stability is not guaranteed for other frequencies due to the limitations of this chipset.

CPU Ratio

After you have selected the host clock, choose the right multiplier for the CPU. Options are: [2, 2.5, 3., 3.5, 4, 4.5, 5, 5.5,6,6.5,7.0,7.5,8.0]. The CPU frequency is then defined as [host clock freq.]x[multiplier], and should the working frequency of your Pentium® III & Pentium ® II processor.

Auto Detect DIMM/PCI Clk

Disabled

Enabled

When enabled, this item will

auto detect if the DIMM and Default PCI socket have devices and

will send clock signal to DIMM and PCI devices. When disabled, it will send the clock signal to all DIMM and PCI socket.

Spread Spectrum

 

 

 

Disabled

This item allows you to
