3.3 Advanced Chipset Features
By choosing the [
Advanced Chipset Features
] option from the CMOS
Setup Utility menu (Figure 3-1), the screen below is displayed. This sample
screen contains the manufacturer's default values for the motherboard.
Figure 3-4 Advance Chipset Features
All of the above settings have been determined by the motherboard
manufacturer and should not be changed unless you are absolutely sure of what
you are doing. Explanation of the DRAM timing and chipset features setup is
lengthy, highly technical and beyond the scope of this manual. Below are some
abbreviated descriptions of the functions in this setup menu.
(1) System
Performance:
Optimal:
Select this option will let the system automatically detect its
performance.
Aggressive:
Select this option for better system performance. It increases a
bit of the system performance.
Turbo:
Select this option for a faster system performance. It will increase the
system performance, but it might result in an unstable system.
Expert:
Select this option only if you are a professional user. This will allow
you to set the system performance according to your choice.
(2) FSB
Frequency:
This feature allows the system memory to run at FSB clock speed. Options
include
100 MHz
(
200 MHz
) to
200
MHZ
(
400 MHz
)
.
(3) CPU
Ratio:
It is recommended to keep the default setting for stable system operation.

(4) CPU
Interface:
Optimal:
Select this option will let the system automatically detect its
performance.
Aggressive:
Select this option for better system performance. It increases a
bit of the system performance.
(5) Memory
Frequency:
By SPD:
It automatically detects the memory frequency.
By Sync:
This will cause the memory to detect the CPU’s Ext. frequency and
function synchronically.
WARNING
Overclocking:
This motherboard is designed to support overclocking.
However, please make sure your components are able to
tolerate such abnormal setting, while doing overclocking.
Any attempt to operate beyond product specifications is
not recommended.
We do not guarantee the damages or
risks caused by inadequate operation or beyond
product specifications
.
(6) Memory
Timing:
The function allows you to enable or disable the DRAM timing by SPD.
When it is set to Manual, you can select the DRAM CAS Latency, DDR
SDRAM Cycle Length and Bank Interleave configuration.
(7) AGP Aperture Size (MB):
This function determines the amount of system memory that is given to the
AGP card. Options range from
32MB
to
512MB
. This is a dynamic memory
allotment in that the AGP card will only use the amount of memory that it
needs. The remaining memory, which is not in use, will be available for the
system. For example, if 16MB is allotted to the AGP card and the card only
needs 8MB, the remaining 8MB will be available for system use.
(8) AGP
Frequency:
This function determines the amount of AGP frequency that is given to the
AGP card. Options range from
50 MHz
to
100 MHz
. (default [
Auto
(66MHz)]
)
(9) AGP
8X
Support:
Enable this setting to utilize the 8X mode (twice as fast as 4X) offered by
advanced AGP cards. Your VGA card must support 8X mode in order to take
advantage of the faster speed.
(10) AGP Fast Write Capability:
Selecting [
Enabled
] to allow Fast Write Protocol for 8x/4x AGP to function.
PS:
Not all AGP cards support fast write.
