yeah i have just had a slightly similar prob you can in bios change it you have to go to xmt i think and select profile 1 to match your installed frequency i do not know what bios ur using but YOU CAN DO IT (TYPE IN HOW TO WORK WITH YOUR BIOS YOUTUBE OR SOMETHING IF UR NOT SURE~)
sorry you have to go to advanced memory settings then MEP or something like that and select profile 1
the only thing i can sudgest because i know you can do it, is to search web for your bios and how to change memory frequency's because i have not dealt with your bios i cannot help you anymore than what i have said it works for me

If your RAM supports XMP profiles then you should be able to set the profile in the Ai Overclock Tuner section of the BIOS. If the RAM doesn't support XMP profiles then you can manually set the RAM speed/timings/voltages in the BIOS. I believe they are all found in the Ai Overclock Tuner section of the BIOS. The motherboard owners manual is your friend.
ill try it, but u guys sure my mother board supports kingston hyper x at 1866, i just saw in supports http://dlcdnet.asus.com/pub/ASUS/mb/LGA1155/P8Z77-V_LE/Z77_DRAM_QVL_1121.pdf this one and there is not my ram at 1866 mhz, i dont know but maybe its the problem? because when i manually change ram speed from 1333 to 1866 as i said PC did not turn on

I'll have to research more when I'm not at work, but the RAM should work just fine. You have to do more than just change the RAM speed, though. As I stated, you also have to change the timings and voltage to the manufacturer specs for your RAM. I'm not surprised that it didn't boot if all you did was change the speed...

If you're not comfortable with setting the RAM speed/timings/voltage after reviewing the motherboard owners manual then you should just let it run at 1333 MHz. You won't notice any real-world difference between 1866 MHz and 1333 MHz, especially with an Intel build.
i just found a picture on google, its similar to my motherboard http://i1216.photobucket.com/albums/dd376/sanjoseparaiso/23072012156.jpg my bios shows: target turbo speed 3600 as it should be and target dram 1333 instead of 1866 maybe from this picture u can guide me, if not ill just leave it

The memory frequency is listed right there in the middle of that screenshot. What options do you get for the memory frequency when you select it?
ok guys i take picture of my AI TWEAK http://oi42.tinypic.com/fa1ob8.jpg please help me if possible. AI overlock tuner has only Auto and manual there is no profile 1. I tryied 1600 mhz ram it worked on auto. and one more note my motherboard memory slots doesnt work on parallel, i mean it works only on blue and black, double blue doesnt working. i hope somebody can help me to get 1866 mhz from this picture
