Mainboard debugging tip
========================================================

If you are experiencing problems with your system and thinking that it might be a motherboard problem, please review the following few items first:
 

• Power Supply
• BIOS Version.
• Advanced memory control in CMOS
• Overclocking memory modules

==============

POWER SUPPLY:

==============

POWER SUPPLY supply voltage distribution must be considered. High speed chips such as the Pentium III 600 or 700 series draw more wattage from the power supply. An 800 AMD "Athalon" Chip uses 22 watts of power from the standard 3.3 Volts distributed to the main logic board. As current systems are built using a variety of high end processing components, each one requiring particular wattages, the final PC system may have exhausted the power supplys' ability to distribute adequate power to all components effectively. (No one wants to hear that a power supply may be the culprit in a system crashing, but it may be the problem, nevertheless).  We recommend the HIGH POWER brand power supplies and cases which have been designed and tested for various models of motherboards, in addition to the SCE motherboards.
 

==========

BIOS Version

==========

Always use the latest released BIOS version.  If you upgrade your BIOS, MAKE SURE YOU ARE USING A PROCESSOR THAT IS SUPPORTED BY THE EXISTING BIOS. Otherwise, the system may hang up while updating, and you must replace the BIOS if this occurs.

=============================

CHIPSET FEATURES SETUP (CMOS)

=============================

Adjust DRAM Speeds in CMOS for CAS Latency and DRAM Timing setting for various RAM speeds.

Bank 0/1, 2/3, 4/5 DRAM Timing. Options are 8ns, 10ns, Normal, Medium, Fast, Turbo.

1. For PC-133 SDRAM, set CAS latency to 3 and DRAM Timing to 8ns.
2. For PC-100 SDRAM, set CAS latency to 2 and DRAM Timing to 8ns.
3. For PC-66 SDRAM, set CAS latency to 2 and DRAM Timing to Normal.
 

==============

OVERCLOCKING

==============

Although many motherboards allow you to overclock the CPU and/or the memory, overclocking configurations can cause instability or even damage your system.  Customer assumes all risk, including risk of damaging any component without warranty service, in doing so.
