Try going into your bios by pressing the F2 or Del key on boot. In your bios you should see a Memory Profile somwhere, change it to X.M.P. and it should change the frequency to the maximum supported frequency if you bought ram that's correctly supported by your motherboard and otherwise it should switch it in most cases correctly as well.
