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.
