System specs please.(at least the motherboard make and model number).
How many RAM sticks do you have?
Mobo - Asrock H110m-HDV
RAM - 2x 8Gb DDR4 (one is 2400 17CL and the other one 2133 15CL)
I heard that different clock speeds and CL numbers can fit together.
And if its the motherboards slot fault, shouldnt it be that it just cant detect the ram and i am able to boot?
