Custom Resolution Utility (CRU)

hey guys, i tried to alter the freesync range from my asus mg279q, but i think i have done a mistake... i want to reset all the original settings to my monitor, but i dont have a clue how this will work. The version from the first page seems not to work (or im just to dumb )

If freesync is on, you can see on picture 1 that the horizontal scan range ist 135-135kHz, vertical scan range is 35-90Hz and video bandwith is 590Mhz, I think that are the default settings.
If freesync is off, the values are 24-222kHz, 50-144Hz and 600Mhz. I dont think that are the default settings, or am i wrong? (picture 2)
When the setting in the OSD is on freesync off, the display runs on 144hz when i restart my computer the screen is slightly longer black i think, before i can enter my passwort. After this the screen is on 60hz again and i cant set it to 144 hz unless i change my monitor via OSD to freesnyc on (there 144hz works and i get the hint that it works only between 35-90hz) and off again (now i can set my screen to 144hz again)
Its the same way around when i restart from freesync "on" setting and 144hz in windows.. i takes slighly longer before i can enter the password and the screen ist set to 90hz (its the max freesync range?!).. i can reenter 144hz ofter i switch on freesync off and on again (then the oblagatory message "freesync only between 35-90hz" appears).

I use the newest AMD crimson driver (15.11.1) on my Windows 10 machine. My graphics card is a r9 390.

I hope you guys can help me to save my monitor..
best regards,

ps.: i installed the older amd driver (from the windows auto update, it contains the catalyst control center instead of crimson), i tried to change the refresh rate, my screen goes black and i got the display port link failure message like this (http://cdn.overclock.net/9/97/97db62f0_FGvdgkm.jpeg). i tried it a second time then it switches to 144hz.
