Note: 3200MHz CL16 is only compatible with laptops equipped with XMP. If your laptop does NOT support XMP, the SO-DIMM 3200MHz CL16 is only operational at a 2666MHz CL19 frequency. For any other frequencies, we recommend opting for SO-DIMM 2666MHz CL19 or 3200MHz CL22 products based on the laptop specs.
