Hello im a bit puzzled. So i have a Alienware aroura r6 16gb. i just bougfht corsair x2 16gb sticks to upgrade to 32gb. However when i look at the speed it seem that its on 2133. WEhen i go to the bios to select the "Overclock" settings its greyed out and will no allow me to do so. My question is how do i get my memory to run faster than 2133 perhaps 2400 or 2800 Mhz and if or is it even possible to do so? Motherboard is IPKBL-SC 7HV66 thanbk you al for your help
