Installation Guide

Getting Started

WARNING!

Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To protect them against damage from static electricity, you should follow some precautions whenever you work on your computer.

1.Unplug your computer when working on the inside.

2.Use a grounded wrist strap before handling computer components. If you do not have one, touch both of your hands to a safely grounded object or to a metal object, such as the power supply case.

3.Hold components by the edges and try not touch the IC chips, leads or connectors, or other components.

4.Place components on a grounded antistatic pad or on the bag that came with the components whenever the components are separated from the system.

5.Ensure that the ATX power supply is switched off before you plug in or remove the ATX power connector on the motherboard.

Installing the motherboard to the chassis…

If the motherboard has mounting holes, but they don’t line up with the holes on the base and there are no slots to attach the spacers, do not become alarmed you can still attach the spacers to the mounting holes. Just cut the bottom portion of the spacers (the spacer may be a little hard to cut off, so be careful of your hands). In this way you can still attach the motherboard to the base without worrying about short circuits. Sometimes you may need to use the plastic springs to isolate the screw from the motherboard PCB surface, because the circuit wire may be near by the hole. Be careful, don’t let the screw contact any printed circuit write or parts on the PCB that are near the fixing hole, otherwise it may damage the board or cause board malfunctioning.

8TX Motherboard

You may use the 4 screws which come with the mainboard to reinforce the support between P4 CPU heat-sink on the mainboard and chassis.

Please note! In order to follow the installation steps below; your chassis must be WILLMETTE/850 board design compatible.

Step1: The 4 new mounting holes on the chassis are for additional support for P4 CPU heat-sink on the mainboard.

Step2: Please remove 4 sets of plastic Push-pins as indicated on Figure2. Remove the white pins first, then black pins as indicated on Figure3.

Step3:	Step4: Fit the 4 screws with 2 CPU retention
	modules on the chassis..

Installation Guide

To set up your computer, you must complete the following steps:

Step 1 - Set system jumpers

Step 2- Install the Central Processing Unit (CPU) Step 3-Install memory modules

Step 4-Install expansion cards

Step 5-Connect ribbon cables, cabinet wires, and power supply Step 6-Set up BIOS software

Step 7-Install supporting software tools

CPU Speed Setup

The system bus frequency can be switched at 100MHz - 133MHz by adjusting SW 1. (The frequency ratio depend on CPU).

SW1 Select the System Speed at 100MHz - 133MHz.

CPU CLK	1	2	3	4
*100MHz	ON	ON	ON	ON
105MHz	OFF	OFF	ON	ON
110MHz	OFF	ON	OFF	ON
133MHz	ON	ON	ON	OFF

*We recommend you to setup your system speed to 100MHz. CPU Installation

Please make sure the CPU should be supported to the motherboard.

1.Pull the lever out, than lift up the Lever.

CPU Heat Sink Installation:

CPU Bottom

Pin 1 Indicator

2.Please make sure the Pin1 indicator (gold color) is aligned with 423pinsocket.

Beware: Please check that the heat sink is in good contact with the CPU before you turn on your system. A poor contact will cause over heat, and might cause damage to your processor!

Installation Guide

3.Align CPU and insert it

4.Use qualified fan approved by Intel.

5.Slip the bracket on to the CPU retention and press both end to clip it on the retention. 6.Make sure the CPU fan is plugged to the CPU fan connector, than install complete.

(Please refer to the cooler’s installation manual for detailed installation steps)

-Additional 4 pin connector for 12V current

-Backward compatibility maintained with load sharing capability -Support 12V or 5V CPU VRs

Memory Installation

The motherboard has 4 Rambus In-line Memory Module (RIMM) sockets. The BIOS will automatically detects memory type and size. To install the memory module, just push it vertically into the RIMM Slot .The RIMM module can only fit in one direction due to the two notches. Please note; Both RIMM modules inserted on RIMM1 and RIMM2 slots are recommended to have the same size, frequency. If not, the larger sized module will l be automatically re-sized by BIOS to match the smaller sized module. The same rule applies to both RIMM3 and RIMM4 slots.

You can insert two RIMMs or four RIMMs into RIMM slots, but C-RIMM (Continuity RIMM) modules must be inserted into the empty slots.

RIMM

CRIMM

Check RIMM module if it is supported by the

M/B.

Insert the RIMM module into the slot.

Push the ejector tab towards the RIMM.

ySupports 300&400 MHz Direct Rambus * Channel @ 100MHz host bus frequency.

yMaximum memory array size up to 256MB using 64Mb/72Mb, 512MB using 128Mb/144Mb, 1GB using 256Mb/288Mb DRAM technology

Supports up to 32 Direct Rambus devices per channel

Supports a maximum DRAM address decode space of 4GB

Configurable optional ECC operation

yECC with single bit Error Correction and multiple bit Error Detection

ySingle bit errors corrected and written back to memory (auto-scrubbing)

yParity mode not supported

APIC memory space in hardware. It is the BIOS or system designer’s responsibility to limit DRAM population so that adequate PCI, AGP, High BIOS, and APIC memory space can be allocated.
