i'm not much of an overclocker when it comes to ram, but basically all you have to do is go into the bios and change the settings from 1600 to 1866 and see it its stable, if its not, go back and increase the volts, but not over 1.65 thats max. then try again, if that doesn't work either you need to start reducing ur timings, so also in the bios you just increase each one by one, so go from 9-9-9-24 to 10-9-9-24 if thats not stable go to 10-9-10-24 if not stable, 10-10-10-24 and then 10-10-10-27 or something , and keep going untill your system is stable.
also if you look somewhere on this forum, there was recently a post about memory stress testing so you can go there and read what you should do to test if your ram is stable at any new settings.
personally OC'ing the RAM is gonna take you a while if you aren't really good at it (like myself) so i wouldn't touch it because you are going to see SOO little difference in preformance. you might increase some benchmark by a few percent but you probably will not notice anything when just using ur computer.
