Hi, my i recently made a new build and bought RAM with 1866mhz. I don't know why but some reason since I built it the RAM has always been clocked at 1333mhz, when I have changed the speed manually in the bios and with the gigabyte easytune software it just basically breaks my computer, It refuses to boot properly and then when it does it gets in a boot loop sometimes, the only way to revert the change is with a CMOS reset. Is there anyway to change the speed to 1866 and not have it break everything?
