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 Clk
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 elec- tromagnetic interference (EMI).
CPU Voltage
This item allows you to increase the CPU voltage.
Memory 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.
