Chipset Configuration

DRAM Frequency

If [Auto] is selected, the motherboard will detect the memory module(s) in-

serted and assigns appropriate frequency automatically. You may also select

other value as operating frequency: [133MHz (DDR 266)], [166MHz (DDR 333)],

[200MHz (DDR 400)].

Configure DRAM Timing by SPD

Select [Enabled] will configure the following items by the contents in the SPD

(Serial Presence Detect) device.

DRAM CAS# Latency

Use this item to adjust the means of memory accessing. Configuration

options: [Auto], [2.5], [2], and [3].

DRAM RAS# Precharge

This controls the idle clocks after a precharge command is issued.

Configuration options: [4 Clocks], [3 Clocks], and [2 Clocks].

DRAM RAS# to CAS# Delay

This controls the latency between the DRAM active command and the

read / write command. Configuration options: [4 Clocks], [3 Clocks],

and [2 Clocks].

DRAM Precharge Delay

This controls the number of DRAM clocks for RAS minimum. Configura-

tion options: [8 Clocks], [7 Clocks], [6 Clocks], and [5 Clocks].

DRAM Burst Length

DRAM Burst length can be set as [8] or [4].

Init. Graphic Adapter Priority

This allows you to select [PCI/AGP] and [AGP/PCI] as the initial graphics

adapter priority. The default vaule is [PCI/AGP].
