Hi, I have Vengeance LPX DDR4 2 x 4GB on my motherborad since 1 or 2 years. I decided to add 2 x (4 GB PC4 - 2400CL17 288 - Pin UDIMM) on my ASUSTeK PRIME Z370-P. Unfortunately it doesn't work :-(. The new memory, alone, works on every slot (1 to 4), but computer does not start in addition of my old Vengeance LPX. Of course Vengeance is still working if I remove my new memory. Someone have any idea of what I can do to have my 4 x 4GB of memory working together ? Thansk a lot.
