ECS KN1 SLI Extreme Review

Packaging »


I would like to thank ECS for supplying the tested motherboard.

At this year's Computex in Taiwan, ECS announced the big brother of the successful KN1 Extreme Motherboard - the ECS KN1 SLI Extreme. It is based on NVIDIA's nForce4 SLI chipset and aims at delivering an affordable SLI motherboard, while still having features like Dual Ethernet and IEEE1394.

In order to increase cooling performance, ECS has added a small thermal exhaust fan to the back panel. Another handy feature in cases where your BIOS gets corrupted, is the inclusion of the top-hat flash, a small device with an extra BIOS chip on it which you snap onto the existing chip on the motherboard.

Not only does the chipset support PCI-Express and SLI, it also has four SATA-II capable ports with RAID 0/1/0+1 support. Also integrated is a native Gigabit Ethernet controller which can be used with NVIDIA's own firewall solution and ten USB 2.0 ports. On top of that, ECS added another 10/100 MBit Ethernet interface and two more SATA-II ports.
