Hi there,
I have a Asus Sabertooth Z87 10 months now but i think i have a little problem, everytime i am trying to change something on her at bios like mhz on ram or overclock my cpu a little bit, or even trying to change the fan speeds with Asus AI i get blue screen so i have 2 choices or sending for service at Asus and waiting 30+ days for repair or sell her for 150€ and buy a new Asus Ranger Z97 for 130€.

Is it worth ? I see that Ranger is good value motherboard. I saw Hero too i can buy her for 160€ but it doesnt have much more feuture to worth buy her instead of Ranger.
