1 nForce4

A chipset released by NVIDIA in October 2004. The chipset supports AMD 64-bit processors ( Socket 939 and 754) and DDR400 RAM.

The boards come in 3 different versions

• nForce4
• nForce4 Ultra
• nForce4 SLI

2 Common Features

• Support for up to 20 PCI-Express lanes. Reference boards are setup with 1 16x and 3 1x leaving 1 unused.
• Support for up to 10 USB 2.0 ports
• Support for 4 SATA and 4 PATA drives, which can be linked together in any combination of SATA and PATA to form a RAID 0, 1 or 0+1.
• NVIDIA RAID Morphing , allows conversion from one RAID type to another on the fly.
• NVIDIA nTune , a tool for easy overclocking and timing configurations.
• 8 channel AC97 audio
• Onboard Gigabit Ethernet
• NVIDIA ActiveArmour an onboard firewall solution

3 nForce4 vanilla

The cheap version of the board will have no special features and will have the HyperTransport link limited to 800MHz on Socket 754 motherboads.

4 nForce4 Ultra

The Ultra version will contain all of the features of the vanilla version with the addition of:

• Hardware processing for the ActiveArmor to reduce CPU load
• No 800 MHz limit on HyperTransport
• 3Gb/S transfer speeds for SATA drives

5 nForce4 SLI

The SLI version has all the features of the Ultra version in addition to SLI (Scalable Link Interface). This interface allows 2 video cards to be connected together to produce a single output. This nearly double framerates by splitting work between the two GPUs.
