RAM upgrade

Hello,

I have an ASUS Prime A320M-K motherboard with 8GB of DDR4 DIMM RAM - 2666MHz and I just bought 2 sticks of 8GB DDR4 3200MHz. After installing the sticks, the PC won't start. I rolled back and the PC works correctly. Do you know why?

    Hello,

    Physically, no limitation, it should boot. The 3200s are an XMP profile, not a JEDEC profile, so the RAM should natively default to a JEDEC profile (2133/2400) before enabling, from the BIOS, applying an XMP profile.


    So the two sticks, after learning, will still be seen only at 2133/2400.


    Memory learning can take time and may make it seem like a KO boot.


    You must wait 10 minutes or the PC may shut down outright before concluding a KO.

    After that you can help the BIOS from the currently functioning config:

    - Disable XMP

    - F5 or "load defaults" after saving the existing config into a profile

    - Try a first learning with a single 3200 stick and let it run for 10 good minutes

    Stay tuned ;-)

    Hello,

    Just having DDR4 isn’t enough for it to work; you have to consider the motherboard and processor memory controller and the compatibility list for the RAM sticks to be sure it works 100%, even though most of the time it does, but if a kit doesn’t work you should return it and try another one.

      The clips aren’t on the list, but I managed to get them working. Remaining task: optimization. Thanks

        Hello

        as for the 3200MHz, you may have restrictions due to the memory controller on the motherboard and/or the CPU

    Default BIOS, 1 stick installed, 25 minutes after startup still nothing. The PC does not shut down, however.

      Arf.

      I’m not sure it's still in learning mode: even my CM Workstation doesn't take this long to change a CPU --'

      We can try updating the BIOS from the functional config


      With the BIOS Update Manual here : 

      If despite that, it’s still KO :

      - still to check all RAM slots with the 2 sticks alone, 8 boot if 4 slots

      - and give the CPU and RAM sticks ref. There might be a chance that they don’t have EXPO profile but it doesn’t matter, for me the JEDEC default profile should have taken precedence and allowed the boot, even with a degraded frequency/latency pair.

        EZ update tells me that my BIOS is up to date.

        I only have 2 RAM slots. I’m running with an old 2666MHz stick in slot 1. I tried one of the two new sticks in slot 1, I’ll try the second one alone. Can I try a new stick with the old one at 2666MHz even if the frequencies differ?

        Miracle, After putting the sticks in slot 2 with the old one in slot 1, I did indeed have 16 GB but not optimal with 2 different frequencies. I put them in solo afterward, 8 GB each without issue, and now I have both and it works. However, the frequency at 1466 MHz (see photo) is that normal?

    No, it’s brand new

    Hi

    Can we assume that the 3200MHz kit is used?

    That could explain... if that’s the case.
