1-2-1 Overview
• Support both Slot 1 & Socket 370 CPU interface (You can only use one CPU interface
at a time).
• Support Ultra DMA 66 for newer hard disk interface.
• Support Jump-less solution for setting Front Side Bus Frequency (CPU Host Clock)
• Support Jump-less solution for setting Front Side Bus Frequency (CPU Host Clock)
and CPU ratio under CPU Host/PCI clock of CHIPSET FEATURES SETUP.

“ DRAM Clock”.
• Conditionally support 66MHz~140MHz* of Front Side Bus Frequency. This function
allow user select CPU Bus Frequency by the BIOS to approach Over-Clock possibility.
• Provide PC Health Monitoring to track CPU temperature, system temperature, system
voltage, and fan speed. When CPU current temperature is over CPU warning
temperature, system will slow down automatically in order to reduce the CPU’s
temperature. (Option for motherboard that embedded PC Health chip)
