    Question ASUS ROG Strix X570-E Gaming Motherboard not supporting more than 32 GB RAM

    Hello all,

    I have recently built a new PC using the ASUS ROG Strix X570-E Gaming Motherboard along with a Kingston HyperX Predator RGB 64 GB (4 x 16 GB) DDR4-3200 CL16 Memory set (HX432C16PB3AK4/64) which was included in the compatibility document for the motherboard but could not managed to make the system post by using the full 64 GB RAM modules installed.

    The system booted properly with just 2 memory modules installed (32 GB: 2 x 16) installed in slots 2 and 4.
    According to the motherboard specs, it is supposed to support up to 128 GB of RAM and the memory kit should be working fine with full 4 slots used.

    Is there somebody who experienced a similar situation?
    I'm ok with 32 GB, since it is still a lot of RAM but would love to take full advantage of the purchased memory set. Is there anything that could be done to achieve that?, am I missing something?

    Another important thing to mention is that the CPU used in the build is: AMD Ryzen 9 3950X 3.5 GHz 16-Core.
    Please find the system full specs shown in my about section for further reference.

    Thanks in advance and best regards.

    Hello JMHR,


    Is your BIOS up to date and have you tried clearing CMOS? Also, have you made sure that all 4 sticks are working and none are defective?

    Hello cljustin, thanks for the quick reply.

    Yes, I have updated the BIOS to 2606 version which is the latest version and cleared CMOS.
    Had the opportunity to test the 128 GB (4 x 32 GB) of the same brand (Kingston Predator, but 3600 mHz) and got a similar result: just managed to make the system boot with only one stick (32 GB) installed in slot 3 (which was kind of weird, to be honest).

    The motherboard came with the 2307 BIOS version installed from factory.
