知道为什么每次循环错误率都会下降吗？

    更换内存模块。如果问题仍然存在，请硬件支持人员协助更换可能出现故障的其他组件，如风扇、电源、CPU 或系统板。

    检查错误检测硬件、ECC 内存和其他 RAS 功能，以查明究竟是什么地方出现了故障。

    memtester 不会告诉您硬件在哪里或为何出现故障，只会告诉您数学函数的存储值不符合预期。

    隔离温度、电压和辐射等环境因素、找出哪些物理模块可能存在问题以及找出间歇性问题的原因（这更困难），需要花费大量时间。对于易耗组件来说，这样做不值得，应将其停产。也许可以将它们放在您不关心的测试环境中，以观察此类硬件故障是否会对您的工作负载造成问题。
