Advanced Chipset Features

This option displays critical timing parameters of the mainboard. Leave the items on this menu at their default
settings unless you are very familiar with the technical specifications of the system hardware. If you change
the values incorrectly, you may introduce fatal errors or recurring instability into the system.

DRAM Timing Selectable
Set this to the default value to enable the system to automatically set the SDRAM timing by SPD (Serial
Presence Detect). SPD is an EEPROM chip on the DIMM module that stores information about the memory
chips it contains, including size, speed, voltage, row and column addresses, and manufacturer.
CAS Latency Time
When the DRAM Timing Selectable is set to [Manual], this field is adjustable. When synchronous DRAM is
installed, the number of clock cycles of CAS latency depends on the DRAM timing.
DRAM RAS# to CAS# Delay
When the DRAM Timing Selectable is set to [Manual], this field is adjustable. This field lets you insert
a timing delay between the CAS and RAS strobe signals, used when DRAM is written to, read from, or
refreshed. Fast gives faster performance; and Slow gives more stable performance. This field applies only
when synchronous DRAM is installed in the system.
DRAM RAS# Precharge
When the DRAM Timing Selectable is set to [Manual], this field is adjustable. This setting 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.
** VGA Setting **
The following items allow you to configure the settings about On-Chip VGA.
Panel Number
This setting auto-detects the panel resolution and other panel settings. Unless you changed the panel, leave
this setting at its default.
