Before You Begin…
Parts OT in the Kit
This kit contains all the hardware necessary to install and connect your new
XFX nForce® 680i LT SLI motherboard. Howe er, it does not contain the
following items that must be purchased separately to make the motherboard
functional.
Intel microprocessor:
Intel Core 2 Extreme, Intel Core 2 Duo Pentium EE, Pentium
Cooling fan for the microprocessor
System memory support:
Supports dual channel DDR2 533/667/800, and up to 800 MHz SLI-Ready
Memory. Supports up to 8 GBs DDR2 memory.
Graphics Card
This motherboard is capable of using the NVIDIA SLI technology. To utilize
this technology requires two SLI-capable graphics cards. When ordering a
graphics card, be sure it is a PCI Express card. The kit does contain the SLI
connector used to connect the two graphics cards. See Installing Graphics Cards
in an
SLI Configuration on page 102.
Power Supply
The power supply requirement is dependent upon the power and the number
of the GPUs you install. If you are going to SLI two graphics cards, you are
going to require more power. As a rule, for one GPU you need a minimum of
a 300 W power supply. If you ha e two GPUs in an SLI configuration, you
will need a minimum of a 500 W power supply. To calculate the power you
are going to require for your specific configuration, go to www.slizone.com.
These instructions tell you how to install each of the parts listed so you can
ha e a functioning motherboard. As you go through the installation
instructions, we are assuming you ha e purchased the necessary parts.

Introduction

Intentions of the Kit
This kit pro ides you with the motherboard and all connecting cables necessary
to install the motherboard into a PC chassis. If you are building a PC, you will
use most of the cables pro ided in the kit. If howe er, you are replacing a
motherboard, you will not need many of the cables.
When replacing a motherboard in a PC chassis, you will need to reinstall an
operating system e en though the current dri es ha e an operating system.

Introduction to the
XFX nForce 680i LT
SLI Motherboard
Thank you for buying the XFX NFORCE 680i LT SLI Motherboard. This
motherboard offers the tools and performance PC users demand. When
combined with two SLI-Ready NVIDIA GeForce graphics cards, you get
inno ati e NVIDIA SLI Technology for enhanced system performance.
Features
Ultimate Overclocking
Unleash the underlying hardware. With comprehensi e o erclocking tools to
push the limits on front side bus (FSB) speed and support for higher memory
speeds, the NVIDIA nForce 680i LT SLI MCPs were designed for
o erclocking.
Guaranteed FSB speeds
Reach FSB speeds of 1333MHz with a CPU that supports this specification.
High-speed Memory
This board supports high-speed SLI-Ready memory up to DDR2-800 to keep
pace with o erclocked system components.

Comprehensive Overclocking Tools
Award-winning NVIDIA o erclocking tools pro ide a complete kit of tools
gi ing e eryone from the most eteran enthusiast to the no ice o erclocker the
ability to unleash the hardware in their PC.
VIDIA nTune Utility
NVIDIA nTune
™
is a Windows-based utility that has added access to more
settings. Adjust CPU and memory speeds without rebooting. You can also
access most BIOS settings from inside Windows without ha ing to go into the
BIOS. Sa e and automatically load profiles for each application you run.
V BIOS
NV BIOS deli ers easy-to-use tuning to let you ha e full control o er your
hardware including processor oltage tables and memory dri e strengths.
Designed for VIDIA SLI Technology
NVIDIA SLI technology is a re olutionary platform inno ation that allows
users to intelligently scale graphics performance by combining multiple
NVIDIA graphics solutions in a single system with an NVIDIA nForce 680i LT
SLI MCP.
True 2 x16 PCI Express SLI Support
Two full-bandwidth, 16-lane PCI Express links ensure maximum graphics
performance for next-generation GPUs and games. True 2 x16 PCI Express
SLI Support offers twice the PCI Express bandwidth of x8 SLI solutions.
VIDIA SLI-Ready Memory
NVIDIA nForce 680i LT SLI MCP automatically increases bandwidth when
select SLI Certified memory modules are detected.

VIDIA SLI Certified Components
Look for other components including NVIDIA® GeForce® GPUs and system
memory that ha e been certified by NVIDIA to deli er unmatched
performance with XFX nForce 680i LT SLI motherboards. For more
information on SLI Certified components, isit
www.SLIZone.com\nForce
.
DualDDR2 Memory Architecture
A state-of-the-art Dual DDR2 memory controller allows high bandwidth and
low latency data access to the CPU and GPU. Ensures data and information are
relayed through the system as quickly as possible for incredible performance.
VIDIA MediaShield™ Storage
NVIDIA MediaShield is a suite of features that safeguards your most important
digital media assets; always reliable, scalable, and accessible. MediaShield
includes RAID and SATA dri e support.
Multiple Disk Setup
Through a simple wizard-based interface, you can effortlessly set up your dri es
for better data protection, faster disk access or maximum storage capacity.
MediaShield automatically selects RAID 0, 1, 0+1 or 5 configurations according
to your needs. Ad anced users can access RAID options directly.
DiskAlert System
The e ent of a disk failure, MediaShield users see an image that highlights which
disk has failed to make it easier to identify, replace, and reco er.
RAID Morphing
MediaShield allows users to change their current RAID set-up to another
configuration in a one-step process called morphing. This eliminates the need
to back up data and follow multiple steps in the process.
