Before them (1600MHz CL10), I had other modules RAMs (1033MHz CL9 in), so you tell the difference between these two strips of games is perfectly imperceptible. That said, they are more in line with all the components of my PC, which makes me more homogeneous machine.
In short, after verification of full compatibility between your motherboard, processor (s) and parameters offered by the bios, these RAMs are quite commendable.
