Corsair Dominators only running at 1/2 speed on Rampage III Extreme

I have an Asus Rampage III Extreme motherboard and 12 GB Corsair Dominator DDR3 1866mhz RAM. Today I ran CPU-Z and it informed me that my memory is running at 934.6 mhz. I went into my BIOS and checked the settings. I made sure it was set to XMP and the DRAM frequency was set to DDR3-1866. The odd part was the voltage, which read as ~1.654. I tried to change it to 1.65, but it would just go back. So... What should I do? I made sure the CAS# and RAS# to CAS# and all those timings were right. I've seen my processor underclock itself when it's not under load, presumably due to Turbo Boost. Might that be the culprit?
