The motherboard comes with dual 940-pin sockets for the AMD Opteron™ 64 processors. The processors are based on AMD’s 64-bit and 32-bit architecture, which represents the landmark introduction of the industry’s first x86-64 technology, provide a dramatic leap forward in compatibility, performance, investment protection, and reduced total cost of ownership and development.

PCI Express™ interface PCI Express™ interface

PCI Express™ interface

PCI Express™ interface PCI Express™ interface

The motherboard fully supports PCI Express, the latest I/O interconnect technology that speeds up the PCI bus. PCI Express features point-to-point serial interconnections between devices and allows higher clockspeeds by carrying data in packets. This high speed interface is software compatible with existing PCI specifications. See page 2-17 for details.

Employing the Double Data Rate (DDR) memory technology, the motherboard supports up to 4GB of system memory using DDR400/333/ 266 DIMMs. The ultra-fast 400MHz memory bus delivers the required bandwidth for the latest 3D graphics, multimedia, and Internet applications. See page 2-12.

Serial ATA 3Gb/s technology Serial ATA 3Gb/s technology

Serial ATA 3Gb/s technology

Serial ATA 3Gb/s technology Serial ATA 3Gb/s technology

The motherboard supports the next-generation Serial ATA 3Gb/s technology through the Serial ATA interfaces and the NVIDIA® nForce4® PRO chipset. The SATA 3Gb/s specification provides twice the bandwidth of the current Serial ATA products. Additionally, Serial ATA allows thinner, more flexible cables with lower pin count, and reduced voltage requirement. See pages 2-24.

Onboard RAID controllers provide the motherboard with dual-RAID functionality that allows you to select the best RAID solution using IDE or Serial ATA devices.

The NVIDIA

nForce4® PRO allows RAID 0, RAID 1, RAID 0+1 and JBOD configuration for four SATA and two PATA connectors. See pages 2-23 and 2-24 for details.

The LSI 1020A controller (

The CPU temperature is monitored by the ASIC (Winbond W83792D) to prevent overheating and damage. The system fan rotations per minute (RPM) is monitored for timely failure detection. The ASIC monitors the voltage levels to ensure stable supply of current for critical components. See section “4.4.8 Hardware Monitor” on page 4-27.

2.1 Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.

• Make sure that your power supply unit (PSU) can provide at least the minimum power required by your system. See “10. ATX power connectors” on page 2-28 for details.

• Unplug the power cord from the wall socket before touching any component.

• 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

• Hold components by the edges to avoid touching the ICs on them.

• Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

OverviewOverview

Overview

OverviewOverview

The motherboard comes with dual surface mount 940-pin Zero Insertion Force (ZIF) sockets designed for AMD Opteron™ 64 processors.

The 128-bit-wide data paths of these processors can run applications faster than processors with only 32-bit or 64-bit wide data paths.

Take note of the notched corner on the CPU. This corner should match a specific corner on the socket to ensure correct installation.

To install a CPU:

1. Locate the CPU socket on the motherboard.

K8N-DRE CPU Socket 940

• Before installing the CPU, make sure that the socket box is facing towards you and the load lever is on your left.

• If installing only one CPU, use the CPU socket marked CPU1.

2. Unlock the socket by pressing the lever sideways, then lift it up to a 90°-100° angle.

Socket LeverSocket Lever

Socket Lever

Socket LeverSocket Lever

Make sure that the socket lever is lifted up to 90°-100° angle, otherwise the CPU does not fit in completely.

3. Position the CPU above the socket such that the notched corner matches the socket corner with a triangle mark.

4. Carefully insert the CPU into the socket until it fits in place.

The CPU fits only in one correct orientation. DO NOT force the CPU into the socket to prevent bending the pins and damaging the CPU!

5. When the CPU is in place, push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked.

6. Repeat steps 1-5 to install a second processor in CPU 2 socket.
