The new ASUS K8N-DL is the only workstation/server motherboard from ASUS that supports dual AMD Opteron processors. The board is based on NVIDIA's nForce4 Professional chipset which is basically a modified version of their nForce4 series for the desktop. This single chip solution provided by NVIDIA enables motherboard manufacturers like ASUS to design highly integrated motherboards for high-end workstations or servers.

The highly integrated nature of the board makes it hard to classify it as a board suitable for server applications as the board doesn't come built-in with usual devices like graphics or dual LAN ports. What ASUS has offered with the K8N-DL is a full suite of features more adapted for workstations and even the occasional hardcore user. With devices like an eight-channel audio codec, optical and coaxial S/PDIF output jacks and IEEE 1394a support, it's likely that the board is targeted at high-end digital video editing enthusiasts.

The ASUS K8N-DL dual Opteron motherboard is jam packed with features as we run through some of them on the following pages.
