Mainboard nForce 680i SLI/Mainboard nForce 680i LT SLI1Chapter 1. Getting StartedIntroductionThanks for choosing nForce 680i SLI/ nForce 680i LT SLI mainboards. They are based onnVIDIA® nForce 680i SLI/ 680i LT SLI Northbridge and Southbridge chipsets. The nForce 680iSLI/ 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 to1333 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 capacityof 8 GB.These mainboards provide two PCI-E x16 slots which can be used with two identicalSLI-ready PCI-Express graphics cards, enabling SLI Technology and significantly increasinggraphics performance . Furthermore, the nForce 680i SLI also providesone PCI-E x8 slot for use with a graphics card. There are two PCI-E x1 slots provided for usewith PCI-E x1 compatible expansion cards. Two standard PCI slots for use with standard PCIexpansion cards are also allowed.The nForce 680i SLI/ nForce 680i LT SLI provide one floppy disk drive connector that can beused with 360KB/720KB/ 1.2MB/1.44MB/2.88MB drives. There is also one IDE connector forconnecting two IDE hard drives supporting Ultra ATA 33/66/100/133. Moreover, thesemainboards come with Serial ATA II feature, six SATA II connectors which the interfaces canprovide the transmit rate up to 3 Gbps and also support RAID 0/ 1/ 0+1/ 5 JBOD mode 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 anInternet 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 SLImainboard. 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 arefor reference only.
