1.3Special Features
Easy Overclocking
•Quickly adjust CPU frequency multiples with BIOS in JumperFree™ Mode
•Adjustable FSB/MEM/PCI frequency ratio
•Stepless Frequency Selection (SFS) for fine-tuning system bus frequency from at 1MHz increments
•Alternatively, easy-to-use DIP switches permit manual adjustment of the processor external/internal frequency settings.
ASUS C.O.P. (CPU Overheating Protection): With AMD® Athlon XP™ installed, the motherboard offers automatic CPU Overheating Protection to prolong the life of the entire system. If the CPU temperature exceeds the set criteria, the PC shuts down automatically.
Temperature, Fan and Voltage Monitoring: CPU temperature is monitored by the ASIC through the CPU’s internal thermal diode to prevent overheating and damage. The CPU and system fans can be monitored for RPM and failure. System voltage levels are monitored to ensure stable voltage to critical motherboard components.
ACPI Ready: Advanced Configuration Power Interface (ACPI) provides more Energy Saving Features for operating systems that support OS Direct Power Management (OSPM).
Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI master busses to the memory and processor.
Auto Fan Off: The system fans powers off automatically even in sleep mode.
Dual Function Power Button: Push the power button for less than 4 seconds when the system is operating places the system into sleep or soft-off modes, depending on the BIOS or OS setting. If the power button is pressed for more than 4 seconds, the system enters the soft-off mode regardless of the BIOS setting.

2.3Before you proceed
Take note of the following precautions before you install motherboard components or change any motherboard settings.
CAUTION!
1.Unplug the power cord from the wall socket before touching any component.
2.Use a grounded wrist strap or touch a safely grounded object or to a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.
3.Hold components by the edges and do not to touch the ICs on them.
4.Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.
5.Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.
NOTE! When lit, the onboard LED indicates that the system is ON, in sleep mode or in soft-off mode, not powered OFF. See the illustration below.

Each AMD CPU has a “marked” corner. This corner is usually indicated with a notch, and/or a golden square or triangle. Refer to this indicator while orienting the CPU. See the next section for installation details.
A fan and heatsink should be attached to the CPU to prevent overheating.
12 |
Chapter 2: Hardware information |
2.4.2 Installing the CPU
Follow these steps to install a CPU:
1.Locate the Socket 462 and open it by pulling the lever gently sideways away from the socket. Then lift the lever upwards. The socket lever must be fully opened (90 to 100 degrees).
2.Insert the CPU with the correct orientation. The notched or golden corner of the CPU must be oriented toward the inner corner of the socket base nearest to the lever hinge.
CAUTION! The CPU should drop easily into place. Do not force the CPU into the socket to avoid bending the pins. If the CPU does not fit, check its alignment and look for bent pins.
4.Once completely inserted, press the CPU firmly and close the socket lever until it snaps shut.
5.Place the CPU fan and heatsink on the CPU. The heatsink should entirely cover the CPU. Carefully attach the heatsink locking brace to the plastic clips on the socket base. With the added weight of the CPU fan and heatsink locking brace, no extra force is required to keep the CPU in place
CAUTION! Take care not to scrape the motherboard surface when mounting a clamp-style processor fan, or else damage may occur. When mounting a heatsink onto your CPU, make sure that exposed CPU capacitors do not touch the heatsink, or damage may occur!
NOTE! Do not neglect to set the correct Bus Frequency and leave the CPU Multiple setting at default to avoid start-up problems.

2.5System memory
2.5.1 Overview
This motherboard uses only Double Data Rate (DDR) Synchronous Dynamic Random Access Memory (SDRAM) Dual Inline Memory Modules (DIMMs). These sockets support up to 3GB system memory using non-ECC , unbuffered PC2700/PC2100/PC1600 DIMMs.
Each DIMM socket/module is two-sided: each side defines one “row” of memory. DIMMs come in combinations of single or double-sided types ranging through 64MB, 128MB, 256MB, 512MB and 1GB to form a total memory size of 64MB to 3GB.
~ Three (3) sockets are available for both 266MHz-PC2100 or 200MHzPC1600 DDR DIMMs to form a memory size of 64MB to 3GB. Only two (2) DIMMs will support 333MHz-PC2700; if more than two 333MHz DIMMs are installed, the system automatically reverts to a maximum speed of 266MHz.

A7S333 184-Pin DDR DIMM Sockets
CAUTION! DIMMs are keyed to fit into notches with only one direction. DO NOT force a DIMM into a socket to avoid damaging the DIMM.
•DIMMs with more than 18 chips are not supported.
•ASUS motherboards support SPD (Serial Presence Detect)DIMMs.
This is the memory of choice for best performance vs. stability
• BIOS shows DDR SDRAM memory on bootup screen.
•This motherboard supports three pairs of differential clock signals per DIMM.

Chapter 2: Hardware information |
2.6Expansion slots
The motherboard has five PCI slots and one Accelerated Graphics Port (AGP) slot and oen AMR slot. The following sub-sections describe the slots and the expansion cards that they support.
WARNING! Unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause you physical injury and damage motherboard components.
2.6.1 Installing an expansion card
Follow these steps to install an expansion card.
1.Before installing the expansion card, read the documentation that came with it and make the necessary hardware settings.
2.Remove the system unit cover (if your motherboard is already installed in a chassis).
3.Remove the bracket opposite the PCI slot. Keep the screw for later use.
4.Align the card connector with the slot and press firmly until the card is completely seated on the slot.
5.Secure the card to the chassis with the screw you removed earlier.
6.Replace the system cover.
7.Set up the BIOS if necessary.
8.Install the necessary software drivers for your expansion card.
2.6.2 Configuring an expansion card
Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclusively assigned to one function at a time. In a standard design configuration, 16 IRQs are available but most are already in use. Normally, 6 IRQs are free for expansion cards. If the motherboard has PCI audio onboard, an additional IRQ will be used. If your motherboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free. Sometimes IRQs are “shared” by more than one function; in this case, IRQ assignments are swapped automatically or adjusted through the BIOS firmware.
ASUS A7S333 motherboard user guide |
17 |
IMPORTANT! When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that the cards do not need IRQ assignments. Otherwise, conflicts will arise between the two PCI groups, making the system unstable and the card inoperative.
