Hardware Setup

Central Processing Unit: CPU

The mainboard supports AMD® Athlon™, Athlon™ XP and Duron™

processors in the 462 pin package. The mainboard uses a CPU socket called
Socket A for easy CPU installation. When you are installing the CPU, make

sure the CPU has a heat sink and a cooling fan attached on the top to
prevent overheating. If you do not find the heat sink and cooling fan, contact

your dealer to purchase and install them before turning on the computer.

1. Pull the lever sideways away

from the socket. Then, raise
the lever up to a 90-degree
angle.

2. Look for the cut edge. The cut

edge should point towards the
lever pivot. The CPU will
only fit in the correct
orientation.

3. Hold the CPU down firmly,

and then close the lever to
complete the installation.

Replacing CPU

While replacing the CPU, always turn off the ATX power sup­ply or unplug the power supply’s power cord from grounded
outlet first to ensure the safety of CPU.

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.

AMD Athlon™/Duron™/Athlon™ XP processor requires a 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. If you want
to get more information on the proper cooling, you can visit AMD’s website
for reference.

WARNING! Thermal Issue for CPU

Selects whether DRAM timing is controlled by the SPD (Serial Presence
Detect) EEPROM on the DRAM module. Setting to SPD enables
SDRAM Frequency, SDRAM CAS# Latency, Row Precharge Time, RAS
Pulse Width, RAS to CAS Delay and SDRAM Bank Interleave auto­matically to be determined by BIOS based on the configurations on the
SPD. Selecting User allows users to configure these fields manually.

SDRAM Frequency

Use this item to configure the clock frequency of the installed SDRAM.

SDRAM CAS# Latency

This controls the timing delay (in clock cycles) before SDRAM starts
a read command after receiving it. 2 (clocks) increases the system
performance the most while 3 (clocks) provides the most stable
performance.

Row Precharge Time

This item controls the number of cycles for Row Address Strobe (RAS)
to be allowed to precharge. If insufficient time is allowed for the RAS
to accumulate its charge before DRAM refresh, refresh may be in­complete and DRAM may fail to retain data. This item applies only
when synchronous DRAM is installed in the system.

RAS Pulse Width

This setting allows you to select the number of clock cycles allotted
for the RAS pulse width, according to DRAM specifications. The less
the clock cycles, the faster the DRAM performance.

RAS to CAS Delay

When DRAM is refreshed, both rows and columns are addressed
separately. This setup item allows you to determine the timing of the
transition from RAS (row address strobe) to CAS (column address
strobe). The less the clock cycles, the faster the DRAM performance.

SDRAM Bank Interleave

This field selects 2-bank or 4-bank interleave for the installed SDRAM.
Disable the function if 16MB SDRAM is installed.

BIOS Setup

SDRAM Burst Length

This setting allows you to set the size of Burst-Length for DRAM. Burst­ing feature is a technique that DRAM itself predicts the address of the
next memory location to be accessed after the first address is accessed.
To use the feature, you need to define the burst length, which is the ac­tual length of burst plus the starting address and allows internal address
counter to properly generate the next memory location. The bigger the
size, the faster the DRAM performance.

SDRAM 1T Command

This setting controls the SDRAM command rate. Selecting Enabled al­lows SDRAM signal controller to run at 1T (T=clock cycles) rate. Se­lecting Disabled makes SDRAM signal controller run at 2T rate. 1T is
faster than 2T.

technology allows the CPU to write directly to the graphics card without
passing anything through the system memory and improves the AGP 4X
speed. Select Enabled only when the installed AGP card supports the
function.

AGP Aperture Size

This setting controls just how much system RAM can be allocated to
AGP for video purposes. The aperture is a portion of the PCI memory
address range dedicated to graphics memory address space. Host cycles
that hit the aperture range are forwarded to the AGP without any
translation.

AGP Master 1 W/S Write

The field allows users to insert one wait state into the AGP write cycle.

AGP Master 1 W/S Read

The field allows users to insert one wait state into the AGP read cycle.

AGP Read Synchronization

The field allows you to enable or disable the AGP Read Synchronization
feature.

PCI Delay Transaction

The chipset has an embedded 32-bit posted write buffer to support delayed
transactions cycles so that transactions to and from the ISA bus are buffered
and PCI bus can perform other transactions while the ISA transaction is
underway. Select Enabled to support compliance with PCI specification ver­sion 2.1. Setting options: Enabled, Disabled.
