dz77ga-70k fails without legacy boot

Hello!

I have a strange issue on dz77ga-70k (bios 0063)

here is my specs:

windows 8 x64 as uefi boot

i7-3770k

crucial 2gb XMP-1600-8-8-8-24 *4

MSI geforce GTX670 o.c. (as default video)

The problem is in bios behavior: if I uncheck the "legacy boot" and remain UEFI boot and then save and reload, the system will reload 3 times and then it shows black screen and after that monitor is switching on and there is my windows 8 start screen.

On system prefs I can see that the intel hd graphics 4000 is enabled (but i've disabled it in visual bios)

Then i reload and can't get into bios (Because of black screen!!!)

If I use back to bios button or jumper the system will reload 3 times again, then in bios I can see that legacy boot is turned on, intel hd 4000 is turned on, and memory XMP disabled!!!

WTF?!
