I recently bought the 3700x, as expected, it needed my rog strix x470-F gaming motherboard to update the bios. once that finished i put in the 3700x again and it posted and booted it up. TODAY, the Dram LED light went on while booting up the pc. i re-slotted both sticks, nothing. i then put in my old 2600x and pc booted up. not sure if its my RAM and the CPU is dead.
