dmesg and xorg.log

When I set native monitor mode 1920x1200-60Hz, refresh rate is not switches to 60Hz. It is 42Hz only. Mode 1280x1024 works with 60Hz refresh rate. 

xrandr --output DisplayPort-0 --mode 1920x1200 --rate 60  doesn't help. 

GALLIUM_HUD="fps" glxgears  shows 42HZ as well as monitor OSD menu. 

Linux mint 18 live CD shows 42Hz too, but LMDE2 edition working with 60Hz 

Help please to fix it!

dmesg and xorg.log is attached
