As processor technology pushes to faster speeds and higher performance,
thermal management becomes increasingly crucial when building computer
systems. Maintaining the proper thermal environment is key to reliable
operation. As such, the processor must be maintained in the specified thermal
requirements. AMD recommends the use of high performance thermal inter­face material.

AMD Athlon™/Duron™ processor with a speed of 600MHz and above re­quires LARGER heatsink and fan. You also need to add thermal grease be­tween the CPU and heatsink to improve heat dissipation. Then, make sure that
the CPU and heatsink are securely fastened and in good contact with each
other. These are needed to prevent damaging the processor and ensuring
reliable operation.

You can visit AMD’s web site for more information on proper cooling: http://

www.amd.com/products/cpg/athlon/pdf/cooling_guide.pdf

WARNING! Thermal Issue for CPU

Chapter 2

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 7

then CPU core speed = Host Clock x Core/Bus ratio

= 100MHz x 7
= 700MHz

CPU Clock Frequency Selection Jumper: J17

The default hardware configuration for CPU Front Side Bus frequency
is set at 100MHz. Therefore, to use a 133MHz CPU and have it run at 133MHz,
you need to adjust the CPU clock up to 133MHz by changing the setting of J17.

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.

Introduction to SDRAM

Synchronous DRAM (SDRAM) is a type of dynamic RAM memory
chip that has been widely used starting in the latter part of the 1990s. SDRAMs
are based on standard dynamic RAM chips, but have sophisticated features
that make them considerably faster. First, SDRAM chips are fast enough to be
synchronized with the CPU's clock, which eliminates wait states. Second, the
SDRAM chip is divided into two cell blocks, and data is interleaved between
the two so that while a bit in one block is being accessed, the bit in the other is
being prepared for access. This allows SDRAM to burst the second and
subsequent, contiguous characters at a rate of 10ns, compared to 60ns for the
first character.

SDRAM provides 800 MBps or 1 GBps data transfer depending on
whether the bus is 100MHz or 133MHz.

Chapter 2

2-6

DIMM Modules Combination

At least one DIMM module should be installed on the motherboard.
Memory modules can be installed on the slots in any order. The single-/
double-sided memory modules that each DIMM slot supports are listed as
below:

DIMM 1 DIMM 2 DIMM 3

S/D S/D S/D

S (Single Side): 32MB ~ 512MB
D (Double Side): 64MB ~ 512MB

1. The DIMM slot has 2 Notch Keys “VOLT and DRAM”, so the DIMM

memory module can only fit in one direction.

2. Insert the DIMM memory module vertically into the DIMM slot. Then

push it in.

3. The plastic clip at each side of the DIMM slot will automatically

close.
