i want to overclock my ram from 2133mhz to 2666mhz or higher.
My Spec:
i7 6700k
Asus z170a
To overclock DRAM on an Z170A, it is fairly easy. There are a lot of custom settings on those motherboard that allow you to do so. Check somewhere in your BIOS or the motherboard integrated software, you'll see it somewhere.
