6XV-133 Motherboard - SUPPLIMENTAL FEATURES - IMPORTANT

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

If you are experiencing problems with the 6XV-133. Please review the following FIVE items.

1. BIOS Version.

2. Advanced memory control in CMOS

3. JM1, JM2, JM4 Jumper Settings

4. Power Supply

5. Overclocking memory modules

==========

BIOS Version

==========

The latest released BIOS version is A.4. Version A.5 is being evaluated, and will be released soon. Processors with 133MHz front-side bus speed are not stable with A.3 or earlier BIOS versions. The reason is Version A.3 and earlier versions are released BEFORE 133MHz front-side bus processors became available.

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.

The erroneous POST message suggesting a CAS latency to 2 for PC-133 SDRAM will be corrected with a later BIOS version.

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

JM1 JM2 JM4 Jumper settings in manual update:

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

FOR 66 MHz

JM1 = Short. JM2 = Short. JM4=Short

FOR 100 MHz

JM1 = Short. JM2 = Open. JM4 = Short

FOR 133 MHz

JM1=Open. JM2= Open. JM4=Open

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

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.

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

OVERCLOCKING

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

Although the MB is capable of overclocking the CPU and/or the memory, overclocking configurations are not supported and customer assumes all risk, including risk of damaging any component without warranty service, in doing so.
