i changed the speed to 3000mhz but when i restarted the pc it said something about my settings being able to harm the pc however i went back into the bios and i disabled an option called 'wait for f1 if error' and now it worked to boot into windows but im still scared that i can fry the motheboard so i guess ill have to leave it only at 2666 mhzNo.
It defaults to 2666 automatically. You can't change it on that motherboard.
i managed to change it to 3000mhz but if it says it only supports 2666mhz i guess i will leave it like before.The ram will work, but limited to 2666mhz.
