When compared to the Biostar TForce4 U 775 nForce4 Ultra based chipset, the BIOS is lacking such options as SPP and FSB voltages along with lower VCore and DIMM voltage settings. Also, the HyperTransport design provides x4/x8 up and down links at a maximum limit of 800MHz.

The board ships with an accessory package that includes the standard assortment of IDE/SATA cables and power connectors. ECS includes a driver CD and software utilities for your system. The board fully supports NVIDIA's nTune performance tuning application with version 3.0 being supplied by ECS.
