BIOS Setup

If you selected “Fast” or “Turbo”:

• Make sure to use DDR400.

• It may cause instability to the system. If this happens, set this

field to “User Define”.

• The “Chipset Enhancement” to “Memory Frequency For”

fields are not configurable.

3.1.3.2 Chipset Enhancement

This feature will boost system performance but in some cases

may cause instability to the system.

3.1.3.3 DRAM Timing Selectable

This field is used to select the timing of the DRAM.

By SPD The EEPROM on a DIMM has SPD (Serial Pres-

ence Detect) data structure that stores informa-

tion about the module such as the memory type,

memory size, memory speed, etc. When this op-

tion is selected, the system will run according to

the information in the EEPROM. This option is

the default setting because it provides the most

stable condition for the system. The “CAS Latency

Time” to “DRAM RAS# Precharge” fields will

show the default settings by SPD.

Manual If you want your system to run at a performance

better than the one “By SPD”, select “Manual”

then select the best option in the “CAS Latency

Time” to “DRAM RAS# Precharge” fields.

3.1.3.4 CAS Latency Time

This field is used to select the local memory clock periods.

3.1.3.5 Active to Precharge Delay

The options are 5, 6, 7, 8, 9 and 10.

3.1.3.6 DRAM RAS# to CAS# Delay

The options are 2, 3 and 4.
