Chapter 4: BIOS Setup

System Performance [Optimal]

This field permits change of mode for system performance. When set to

[Optimal], the system uses the most stable settings. When you want to use

overclocked settings for higher performance but with higher risk of instability,

set to [Aggressive] and to allow full customization of performance options

set to [Expert]. Configuration options: [Optimal] [Aggressive] [User Defined]

CPU Interface [Optimal]

This field sets the mode for CPU/FSB parameters usage. Select [Aggressive]

if you want to use overclocked CPU/FSB parameters. Otherwise, the default

value is [Optimal] where it uses the most stable CPU/FSB parameters.

Configuration options: [Optimal] [Aggressive]

Memory Frequency [By SPD]

This field sets the type of memory frequency based on the type of DDR

(Double Date Rate) memory module installed. Resulting frequency can vary

depending on percentage setting which is multiplied by the FSB frqequency.

Normally, the default, by SPD, permits autodetection. Configuration options:

[By SPD] [50%] [60%] [66%] [75%] [80%] [83%] [Sync] [120%] [125%] [133%

[150%] [166%] [200%]

Resulting Frequency

This field displays the resulting memory frequency.

Memory Timing [Optimal]

This field permits change of memory timing mode for system performance.

When set to [User Defined], the next four fields can be set manually. Set to

[Aggressive] for higher performance. Use default [Optimal] to use most stable

settings. Configuration options: [Optimal] [Aggressive] [User Defined]

SDRAM Active Precharge Delay [7]

Row-active delay.

SDRAM RAS to CAS Delay [1]

RAS-to-CAS. This item controls the latency between the SDRAM Active

command to the SDRAM.

SDRAM RAS Precharge Delay [1]

Row-precharge delay.

SDRAM CAS Latency [2.5T]

This field sets the override clock cycle for the latency time between the

SDRAM read command and the moment that the data actually becomes

available. Normally, the system determines the rate automatically by default.

FSB Spread Spectrum [Disabled]

Configuration options: [Disabled] [0.50%] [1.00%]

AGP Spread Spectrum [Disabled]

Configuration options: [Disabled] [0.50%] [1.00%]
