Advanced Chipset Features

The following screen shows the Advanced Chipset Features.

The following table describes each Advanced Chipset Features parameter. Settings in boldface are the default and suggested settings.

Parameter

Description

Options

 

 

 

DRAM Timing Selectable

Selects whether DRAM timing is controlled by the

By SPD

 

SPD (Serial Presence Detect) EEPROM on the

Manual

 

DRAM module. Setting to By SPD enables DRAM

 

 

timings to be determined by BIOS based on the

 

 

configurations on the SPD. Selecting Manual allows

 

 

users to configure the DRAM timings manually.

 

 

 

 

CAS Latency Time

This controls the timing delay (in clock cycles)

2T, 2.5T, 3T

 

before SDRAM starts a read command after

 

 

receiving it. Settings: 2, 2.5, 3 (clocks). 2 (clocks)

 

 

increases the system performance the most while 3

 

 

(clocks) provides the most stable performance.

 

 

 

 

Active to Precharge Delay

The field specifies the idle cycles before

5T, 6T, 7T, 8T

 

precharging an idle bank.

 

 

 

 

DRAM RAS# to CAS# Delay

This field allows you to set the number of cycles for

2T, 3T, 4T

 

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.
