BIOS Setup DRAM RAS# to CAS# Delay This field allows you to set the number of cycles for a timing delay between the CAS and RAS strobe signals, used when DRAM is written to, read from or refreshed. Fast speed offers faster performance while slow speed offers more stable performance. DRAM RAS# Precharge This item controls the number of cycles for Row Address Strobe (RAS) to be allowed to precharge. If insufficient time is allowed for the RAS to accumulate its charge before DRAM refresh, refresh may be incomplete and DRAM may fail to retain data. This item applies only when synchronous DRAM is installed in the system. DRAM RAS# Activate to Prec This item controls the number of cycles for Row Address Strobe (RAS) to be allowed to precharge. If insufficient time is allowed for the RAS to accumulate its charge before DRAM refresh, refreshing may be incomplete and DRAM may fail to retain data. This item applies only when synchronous DRAM is installed in the system. FSB/Memory Ratio This setting control the ratio of CPU FSB / DRAM Clock Ratio to enable the CPU & DRAM to run at different frequency combinations. Please note that the setting options vary according to the CPU FSB Clock preset. Adjust PCI-E Frequency This field allows you to select the PCIE frequency (in MHz). Auto Disable DIMM/PCI Freque This item is used to auto disable the DIMM/PCI slots. W hen set to [Enabled], the system will remove (turn off) clocks from empty DIMM/PCI slots to minimize the electromagnetic interference (EMI). CPU Voltage This item allows you to increase the CPU voltage. M emory Voltage (V) Adjusting the memory voltage can increase the DDR speed. NB Voltage Adjust the North Bridge chipset voltage. SB I/O Power Adjust the South Bridge I/O voltage. SB Core Power Adjust the South Bridge core voltage. 3-21
