Correct. I just left both switches off. Also do not use the oc tuner in bios or the auto tuning tool in AI suite II to overclock. They both tried to o.c. my system too high and made it unstable. There are plenty of overclocking guides on the net for your cpu/mobo combo. I had never oc'ed in my life and had a stable overclock (26000k @ 4.4ghz) within a couple hours. Your best bet is to go on various forums and read the stickies on p8z68/2500k overclocking guides as well as youtube videos. Way easier than you think.
