Chipset Configuration

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

inserted and assigns appropriate frequency automatically. You may also

select other value as operating frequency: [200MHz (DDRII 400)], [266MHz

(DDRII 533)].

The default value of this option is [Disabled]. It will allow better tolerance for

memory compatibility when it is set to [Enabled].

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

SPD (Serial Presence Detect) device. If you select [Disabled], you will find

the items “DRAM RAS# to CAS# Delay”, “DRAM RAS# Precharge”, and

“DRAM RAS# Activate to Precharge” appear to allow you adjusting them.

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

options are [6], [5], [4], [3], and [Auto].

This controls the latency between the DRAM active command and the

read / write command. Configuration options: [2 DRAM Clocks], [3 DRAM

Clocks], [4 DRAM Clocks], [5 DRAM Clocks], and [6 DRAM Clocks].

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

Configuration options: [2 DRAM Clocks], [3 DRAM Clocks], [4 DRAM

Clocks], [5 DRAM Clocks], and [6 DRAM Clocks].
