Things You Have To Know

The images and pictures in this manual are for reference only and may vary

from the product you received depending on specific hardware models, third

party components and software versions.

This mainboard contains very delicate IC chips. Always use a grounded

wrist strap when working with the system.

Do not touch any IC chip, lead, connector or other components.

Always unplug the AC power when you install or remove any device on the

mainboard or when confuguring pins and switches.

Chapter 1. Getting Started

Introduction

Thanks for choosing nForce 680i SLI/ nForce 680i LT SLI mainboards. They are based on

nVIDIA®nForce 680i SLI/ 680i LT SLI Northbridge and Southbridge chipsets. The nForce 680i

SLI/ nForce 680i LT SLI support Intel®CoreTM 2 Extreme/ CoreTM 2 Quad/ CoreTM 2 Duo/

Pentium®Extreme Edition/ Pentium®Processors with FSB (Front Side Bus) frequencies up to

1333 MHz/ 1066 MHz/ 800 MHz.

The nForce 680i SLI/ nForce 680i LT SLI provide four DIMM (Dual In-Line Memory Modules)

sockets allowing you to install 240-pin, unbuffered non-ECC, DDRII 800/ 667/ 533 SDRAMs.

They also support Dual Channel Technology and allow you installing a total memory capacity

of 8 GB.

These mainboards provide two PCI-E x16 slots which can be used with two identical

SLI-ready PCI-Express graphics cards, enabling SLI Technology and significantly increasing

graphics performance <See Appendix III>. Furthermore, the nForce 680i SLI also provides

one PCI-E x8 slot for use with a graphics card. There are two PCI-E x1 slots provided for use

with PCI-E x1 compatible expansion cards. Two standard PCI slots for use with standard PCI

expansion cards are also allowed.

The nForce 680i SLI/ nForce 680i LT SLI provide one floppy disk drive connector that can be

used with 360KB/720KB/ 1.2MB/1.44MB/2.88MB drives. There is also one IDE connector for

connecting two IDE hard drives supporting Ultra ATA 33/66/100/133. Moreover, these

mainboards come with Serial ATA II feature, six SATA II connectors which the interfaces can

provide the transmit rate up to 3 Gbps and also support RAID 0/ 1/ 0+1/ 5 JBOD mode <See

Appendix II>

The onboard High Definition Audio CODEC (ALC885) supports 8/6/4/2 channel audio play

<See Appendix I>. These mainboards also support the Sony/Philips Digital Interfaces (SPDIF)

output function.

The nForce 680i SLI also comes with two onboard 10/100/1000 Mbps Ethernet LAN chips.

There are dual LAN ports on the back panel of your case that you can directly plug into an

Internet cable. The nForce 680i LT SLI only provides one 10/100/1000 LAN port.

There are maximal ten USB2.0/ 1.1 ports which can be set up on the nForce 680i SLI

mainboard. Eight USB2.0/ 1.1 ports are available on the nForce 680i LT SLI mainboard.

All the information (including hardware installation and software installation) in this manual are

for reference only. The contents in this manual may be updated without notice. The company

will not assume any responsibility for any errors or mistakes within.
