NVIDIA's nForce 4: Feature Overview Cont.
nTune Performance Application:
NVIDIA's nForce 4 SLI Intel Edition also fully supports their nTune performance application (formerly known and NVIDIA's System Utility). With NVIDIA's nTune application, users can have the application automatically adjust key aspects of their system (FSB speeds, voltages, memory timings) to maximize performance for any given scenario.
For example, with nTune users can tweak their system to squeeze more performance out of it while gaming, or even clock down the system and lower fan speeds to keep the system quiet while playing a DVD or video file. With nTune users can alter FSB speeds, memory timings, and tweak key voltages. Changes are made within the application, while in Windows, eliminating the need to make changes via the BIOS or reboot the system.
Although SoundStorm is a thing of the past, the nForce 4 SLI Intel Edition does have an AC'97 2.3 compliment audio interface incorporated in the MCP. To compliment the integrated AC'97 audio, NVIDIA provides the nVMixer application with their Forceware driver package to give users the ability to control the audio output from the MCP.
Some of the key features of the NVMixer application include control over all playback and recording volumes, simple tweaking of speaker or headphone configurations, and integrated help information that's available on the same page as the actual feature in question.
SLI (Scalable Link Interface):
The key feature offered by the nForce 4 SLI Intel Edition chipset, is of course SLI. We're not going to go in-depth with an explanation of SLI here, because we've already covered the technology thoroughly in this article,and in this one as well. However for those of you that haven't read those articles, and aren't familiar with NVIDIA's current version of SLI, essentially what it does is allow users to install a pair of PCI Express GeForce 6x00 based video cards into their systems, to share the 3D graphics workload to increase performance. The 20 PCI Express lanes from the SPP can be configured in either a x16 / x1 configuration or in an x8 / x8 configuration to balance the bandwidth available to each video card.
