Advanced Chipset Features

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 the following settings automatically determined by

BIOS according to the configurations on the SPD. Setting options: By SPD, By

User.

CAS# Latency

The field controls the CAS latency, which determines the timing delay

before SDRAM starts a read command after receiving it. Setting options:

1.5, 2, 2.5. 1.5 increases system performance while 2.5 provides more

stable system performance.

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

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.
