Hi, i recently purchased a kit of 16gb 3200mhz hyperx fury ram, to replace my 8gb 2133mhz hyperx fury ram. when the ram is set to a speed of anything above 2666mhz my pc will boot, run fine for a few mins then bluescreen and crash. Then the pc wont boot at all and just keeps crashing before windows loads, i then have to open the bios and set it to 2666mhz. running at anything under that frequency works fine. Is this a compatibility issue or is it a problem somewhere else, My Mobo is the Asrock B450 pro4. Thanks
