3-3 Advanced Chipset Features
By choosing the [Advanced Chipset Features] option from the CMOS Setup Utility menu
(Figure 3-1), the screen below is displayed. This sample screen contains the
manufacturer's default values for the motherboard.
All of the above settings have been determined by the motherboard
manufacturer and should not be changed unless you are absolutely sure of
what you are doing. Explanation of the DRAM timing and chipset features
setup is lengthy, highly technical and beyond the scope of this manual. Below
are some abbreviated descriptions of the functions in this setup menu.
DRAM Timing Selectable
The function allows you to enable or disable the DRAM timing by SPD. It is
recommended to keep the default setting for a stable system operation.
CAS Latency Time
This item controls the latency between DRAM read command and the time the data
actually becomes available.
Active to Precharge Delay
This item controls the number of DRAM clocks used for DRAM parameters.
DRAM RAS# to CAS# Delay
This item controls the latency between DRAM active command and read/write
command.
