I've always been keen to recommend Crucial in the past when people wanted RAM with a lifetime warranty that works as expected. Not until a few years ago did Crucial start offering their Ballistix overclocking RAM. Fast forward to the new DDR3 days of today and we find a new Ballistix PC3-16000 kit that offers speeds of 2000MHz! You'll be pressed to find a board that can even handle this speed, I know I didn't have one.
