Hi!
I have a new build.
My processor is intel 3770k works @ 3.50Mhz
MB AsRock z77 extreme4
DDR3 Corsair Dominator Platinum 2666.
The problem is that memory works only at 1333 frequency.
Enable of XMP makes my MB reboot 2 times and all gone back to 1333
CPUZ shows frequency 667Mhz (x2 = 1333)
Any suggestions how to force memory work @ 2666

Can you set it to 1600Mhz or 2133MHz? According to this, http://www.asrock.com/mb/memory.asp?Model=Z77%20Extreme4, the memory you have is not supported.

But I will take this with a grain of salt; because I am running some G. Skill 2133Mhz on a Gigabyte Z77 UD3H, and according to the website (last time I looked at it, at least) my RAM wasn't supported.

Another problem may be Latency, your MOBO may not like it much at default, so try to make sure in your BIOS that your RAM latency is set to 10-12-12-31.
