ECS KN1 SLI Extreme Motherboard Review :: Layout

By Benjamin Sun

Layout of the ECS board is typical of SLI motherboards. The PCI Express x1 slots are above and below the first PCI Express x16 slot. This positioning means that if you have a 2-slot video card like the 6800 Ultra or x1800XT, one of the PCI Express x1 slots will be unusable.

4-Pin Power


Positioning of the 4-pin power connector is on the top of the board, making for excellent positioning, as it doesn't impede airflow to the CPU cooler. The position of the 24-pin ATX connector is on the top right hand side of the board. This position also allows for easy routing of the ATX power cable. Below the ATX connector is the floppy drive connector. Further down the board is two IDE connectors.

MCP Fan


ECS decided to cool the CPU and MOSFET area with a fan. The fan takes up the area of the input output area of the board normally reserved for the Parallel and Com ports, which this board does not have. The AMD Athlon 64 CPU has the memory controller on the die of the CPU, allowing NVIDIA to make this chipset with a MCP (Media Communications Processor) only, instead of the traditional North and South Bridges. The MCP is cooled by a fan, allowing for cool operation.

Present on the board is 3 USB headers to add additional USB ports via bracket, if needed. The nForce4 SLI chipset supports up to 10 USB ports. Also present on the board are two 1394A headers. Fan headers are plentiful for the tweaker wanting multiple case fans on their computer. There's a CPUFan, two Case Fans, the North Bridge fan and a header for the back fan present on the board.
