How do i get a TA75M+ to use 1866 ram settings ? Every time i think that it is set it shows as 1600 after i reboot. i am using dual channel f3-14900cl9d-8gbxl. Biostar can only tell me to make sure to upgrade my BIOS(it is the newest). I have changed and used different settings given in threads/forums etc. GSkill has wished me a happy Chinese new year. Cpu is a A8-3870K. I have checked my speed with CPUZ.
