Instructions: Hit the "delete" OR "F1" key during system boot-up to enter the BIOS setup.

**This tweaking guide is based on AMI's setup utility version 3.31a on a MSI KT333 Ultra-ARU mobo. So your BIOS might have more/less options.

*I'm going to keep this tweaking guide as simple and short as possible. And I'm ONLY going to be talking about the options/values that are going to affect your system's performance and speed.

=Standard CMOS Features=

Highlight ur Hard Disk/s and hit "enter":
32 Bit Disk Access: Enable for better HD performance.

=Advanced BIOS Features=

Quick Boot:
Leave this setting "Enabled" for faster boot-up sequence.
S.M.A.R.T. for Hard Disks:
Enables/Disables Hard Disk monitoring for possible failures. Disable for better performance.
Internal Cache:
Select "Enabled" or "Writeback" (which ever is available)
System BIOS Cacheable and C000, 32k Shadow:
Disable for better performance and/or stability.

=Advanced Chipset Features=

[DRAM Timing Control]

Configure SDRAM Timing by:
Select "User" to manually configure the next 6 options below
SDRAM Frequency:
I recommend that you leave this option at its default setting (SPD) for better stability.
SDRAM CAS# Latency:
Set to "2" for better performance. Revert back to "2.5" if ur system becomes unstable with the lower setting.
Row Precharge Time:
Set to "2T" for better performance. Set to "3T" if ur system becomes unstable.
RAS Pulse Width:
Set to "5T" for faster performance. Set to "6T" if stability becomes a problem.
RAS to CAS Delay:
Set to "2T" for better performance. Set to "3T" if ur system becomes unstable.
Bank Interleave:
Set to "4-Way" if u have a 64mb (or higher) RAM stick. Set to "2-Way" if u have a 32mb (or lower) RAM stick.
SDRAM Burst Length:
Set to "8 QW" for longer burst length and better performance. Revert back to "4 QW" if ur system becomes unstable.
SDRAM 1T Command:
Set to "Enabled" for better performance. "Disabled" if ur system becomes unstable.
Fast Command:
Set to "Ultra" for better CPU performance. Set to "Fast" or "Normal" if ur system becomes unstable.

[AGP Timing Control]

AGP Mode:
Set to "4x" ONLY if ur videocard support the said setting. If ur uncertain or ur videocard only supports 2x... set to "Auto"
AGP Fast Write:
Set to "Enabled" ONLY if videocard supports the said setting. Consult ur videocard manual for more info.
AGP Aperture Size:
Set to "128mb" or half of ur system RAM. So if u have 512mb RAM for example ... set Aperture Size to 256mb.
AGP Master 1 W/S Write/Read:
Better left "Enabled" for better performance. Set to "Disabled" if u experience graphical problems.
PCI Delay Transaction:
"Enabled" to support PCI version 2.1 devices. If ur hardware doesn't support the said version ... set to "Disabled"

=PNP/PCI Configurations=

PCI Latency Timer:
Set to "32" for faster PCI hardware performance. Set to a higher setting if ur PCI hardware's are having a hard time communicating with each other. Which is often times caused by fast PCI hardware waiting for a slower PCI device to finish its duty.
PCI IDE Bus Master:
Set to "Enabled" for better performance.

=Misc Tips=

On-Board ATA133 RAID:
If u have 2 identical hard drives (identical in terms of speed/performance) ... I recommend that u enable this feature. This will enhance ur HD performance drastically that 2 ATA133 Maxtor 7,200RPM hard drives will outperform most SCSI HD's! Of course ur HD must be connected to the ATA133 RAID IDE connectors. Consult ur mobo's manual for more info.
Spread Spectrum:
Disable this if u want to overclock ur processor. Sudden electrical spikes may cause ur system to become unstable when this setting is enabled.
MSI KT3 Ultra-ARU's CPU Halt Command Detection
This additional feature that is included on MSI's 5.7 BIOS update is a good way of keeping ur CPU cool when idle. But may cause some systems to experience sound stuttering or scratching sound problems. Disabling the said feature will fix the sound probs.

***I will not be held responsible to any damage this tweaking guide might cause your system. Always list your default BIOS settings before changing anything so you can always revert back to your past settings in case something goes wrong!
