I have the Kingston 16gb DDR4 AND A MSI MPG B550 GAMING PLUS MOTHERBOARD. Recently I overclocked the ram to 3200mhz and then I got a black screen and the system won't post so I reset the BIOS and since then the PC won't boot if there is RAM inserted in B2 slot (4th). If inserted in rest of them will work fine.
Sorry to ask, but what is the exact reference (part number) of your RAM ? I am not sure that Kingston sells a 2 x 8 Gb KIT of 3200 Mhz. These could be in fact two singles.
And I am not speaking of Hyperx of course.
