Now more than a week after the chipset was released, SLI seems to still be activated as when Nvidia still has not released drivers that support dual-GPU setup. This problem is revealed by the publication Expreview trying to review the Nvidia SLI setup on the existence of new 990FX motherboard supported by the latest AMD chipset.
By using the beta drivers (275.33) the latest available on the website on both the Nvidia GeForce GTX 570 graphics card that has been recognized by the system, but it's SLI can not be activated because the drivers do not support it.
The latest stable drivers also do not support this functionality, so users who wished would be able to build a SLI setup using AMD system is apparently still have to wait until new drivers are released.
When the 900-series chipsets were introduced, many sites have published numerous reviews 990FX motherboards that run the SLI setup. However, this review itself was even using a custom driver (270.77) which is provided by Nvidia as the drivers testing only.
Another option to run SLI on the motherboard 990FX today is to hack the Quadro drivers (275.36) by following the instructions posted by users on forums Overclock.net.
Based on Nvidia's notice at the end of last April, AMD 900-series chipset will reportedly bring the option to setup SLI support for those who build these solutions have an SLI license.
Motherboard, motherboards are built using the 990FX chipset is reportedly going to be able to support 3-way SLI setup, whereas the 990X motherboard user can activate the 2-way SLI.
The chipset North Bridge 900-series can be paired with AMD's SB950 South Bridge controller to add support to the six existing 6Gbps SATA ports.
