   Yesterday, after change bios settings to uefi defaults, my motherboard dont clock my 2500k higher than stock speed.I'am setting clock to 40 - it reverts me to 37, any setting above 37.
But in system (Windows 10 64bit) clock speed not going higher 3399 (3400 mhz)

I have 20 gb ram (2x2gb 2x8gb) and now working only 2x8gb. Tried to change slots, 2x2gb working, then 2x8gb is not installed. But it's not all... Now i can't change dram speed higher than 1333mhz, 1600 and higher don't showing up in bios.

And...iGPU settings is gone. I'am not using it, but maybe it will help to "help" me.

Tryed to reflash bios 2.10
Tryed to flash 2.10a.
Tryed to restore settings to defaults with CLR_CMOS jumper.
Tryed to restore settings by releasing motherboard battery.
Tryed to flash new Intel Management Engine Firmware (8.1.65.1586_1.5MB_PRD_RGN).

ALL this moves doesn't help me at all. Google can't help me, but found same problem on ASUS forum and there is some "flasher" that help to solve this problem (or not this, but problem is similiar)

PLEASE help me and sorry for English, it's not my native.
