    Why would memory throw errors only only with a given CPU?

    Posted: 23 Feb 2021 09:48 AM PST

    This isn't a technical support question, I am genuinely interested in what goes on behind the scenes from a hardware perspective.

    I have a system config (x570 board, 4 sticks of ddr4 ram) where the memory threw errors on 3600 Mhz (auto settings from the XMP profile) but not on 3200 MHz in test #8 of the memtest86 suite (random reads). The CPU used was Ryzen 3600.

    When replacing the 3600 with a 5900x CPU, the errors from that test are gone and no other appears. None of the CPUs was overclocked in any way, however I understand that driving the memory above 3200 is considered overclock

    So my questions:

    1. Why would the *same* sticks of ram throw errors with one CPU but not with another?
    2. Do I take then memtest86 notification that the ram is faulty with a grain of salt then?
    3. Is it the memory controller on the CPU die? But if so, would that signify that the controller is the RCA of the errors and not the physical sticks?
    4. Any speculation on what is actually going on behind the scenes?

    Thanks!
