[Saksham_5]

hey i want to upgrade my laptop ram:
im really confused on purchasing ram from Amazon between two products..
what should i choose
DDR4 PC4-17000 cl 15 vs DDR4 PC4-19200 cl17
my laptop support forum says:DDR4 PC4-17000 2133MHz Non-ECC SODIMM
Does that crucial DDR4 PC4-19200 cl17 will be compatible with my laptop(ROG-GL552VX).
