It doesn't really matter what the maximum speed is. The default speed is 1333 mhz right now, and you only need to have faster sticks when you're overclocking. 1600 mhz sticks are just rated at the higher speed, and you don't really need to go much higher than that.
I am thinking about using this board also. It supports the latest DO stepped processors. You may want to make sure your memory supports XMP profiles as this is an easy way to set up your overclock memory
