Advanced Chipset Features

The Advanced Chipset Features Setup option is used to change the values of
the chipset registers. These registers control most of the system options in the
computer.
Note: Change these settings only if you are familiar with the chipset.
Configure DRAM Timing
This setting determines whether DRAM timing is configured by reading the
contents of the SPD (Serial Presence Detect) EPROM on the DRAM module.
Selecting By SPD makes SDRAM Cycle Length and Bank Interleave automati-
cally determined by BIOS according to the configurations on the SPD.
CAS# Latency
When synchronous DRAM is installed, the number of clock cycles of CAS
latency depends on the DRAM timing. The settings are: 1.5, 2, 2.5.
Precharge Delay
This setting controls the number of clock cycles for DRAM to be allowed to
precharge from the active state. Setting options: 7, 6, 5.
RAS# to CAS# Delay
This field lets you insert a timing delay between the CAS and RAS strobe
