    DDR4 #1 Slot On Motherboard Not Functioning.

    • I have an H130M A Motherboard, which of which I recently changed the cpu. Before, the ram slot was working, but after I changed it, the ram slot does not work. No matter what I do: I’ve tried clearing the CMOS, I’ve tried different ram, and a different cpu. The computer only boots if I use the second slot. I am hoping I do not need to buy a new board; I would like any assistance if possible.

    Hi and Welcome to PCHF.

    Can you please post your memory/CPU types?

      I’ve installed an i3 8100 and an i7 8700, along with 8gb DDR4, 3000mhz and 2400mhz ram

        The second slot is DIMM slot A1 which is the primary slot and therefore the slot that must be used when there is only the one stick of RAM, this explains why a single stick of RAM will/may not work in the secondary B1 slot.

        Neither of the CPUs or the MB are compatible with DDR4 3000MHz RAM, you can confirm this for yourself at the following links;

        PRIME H310M-A - Intel® Core™ i3-8100 - Intel® Core™ i7-8700

        The reason why both sticks will work on their own in DIMM slot A1 is twofold, they are in the primary memory slot and they are only working in single channel at 50% of what they would in dual channel which is well below the max that either CPU can handle, the speed btw is normally around 1066MHz in single channel.

        Depending on what CPU is in the board now;

        If the i3 8100 you should have two matching sticks of DDR4 2400MHz maximum.

        If the i7 8700 you should have either two matching sticks of DDR4 2400MHz or two matching sticks of DDR4 2666MHz maximum.

        This one of the reasons why you should never mis match RAM and the above will only make a difference if (A) there is no hardware damage and (B) the version of BIOS is appropriate for both the CPU and RAM in the board.
