I have an Asrock Master sli x470 (not ac) and i have two sticks of ddr4 team tforce 3600mhz nighthawk ram. I have gone through bios and MSI Afterburner. I go to task manager and each stick is running at 1200mhz each, 2400mhz. it says this in the bios. the manual is way to vague and im not understanding it correctly. I did buy 3600mhz for it to be 3600mhz
