Hi StarJack...as far as I read over the Internet there is no problem in doing it.
It even gives you that option so you will be fine.
I own a GL702VM (same LCD panel settings as yours) broke my LCD panel last year and went into RMA to put a new one. After that It started to do a lot of flickering when playing games with high fps and some stuttering also...and magicaly after I changed the frequency to 100mHz (overclock) all flickering and stutters stopped.
On games there noticeable difference with 100mhz, graphics response times seems a lot faster and the assets edges seem to be more accurate and beautiful.
If someone has opposite information would be amazing to share with us.
