ASUS mobo not reading RAM correctly. 1333 MHz instead of 1600 MHz

I have an ASUS P7P55D LE motherboard and G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 RAM. When I boot my computer (with Windows 7 Ultimate) on it, the highest I can run my RAM from the BIOS is at 1333 MHz and not at 1600 MHz. How can I change this? I read it doesn't make a big deal but I would just like to it to work in case and for the future. Should I update BIOS or is there another way of changing the frequency?

Thanks!
