I am trying to see if your board supports SSE, there is nothing on the ecs website!
Have you looked in your BIOS to see if there is an option to turn it on?

*!*EDIT*!*
After having another look it seems that ECS has disabled SSE on that board for some reason?
But you can enable it using a third party BIOS??
I don't know about you, but there is no way I would install a third party bios on my machine!!
I can post the links if you want, but hold no responsibility if you mess up your machine!!
