答案1
记忆
您的内存可能未正确安装。
在双通道（四通道）内存控制器配置中，匹配的 RAM DIMM 对安装在通道 A 和通道 B（通道 A/B/C/D）中。不同供应商的命名约定有所不同。
您的银行 0/1/2/3 是正确的，因为 DIMM 安装在 DIMM0 和 DIMM1 对插槽中。
您的 4/5/6/7 组不正确，因为 DIMM 位于 DIMM1 插槽中。您应该将 7 组 DIMM 移至 4 组 DIMM 插槽，这样sudo lshw -C memory就会显示 4/5 组被占用为 DIMM0 和 DIMM1，而 6/7 组为空。
去https://www.memtest86.com/并下载/运行他们的免费记忆测试来测试你的记忆力。至少完成一次所有 4/4 测试以确认记忆力良好。这可能需要几个小时才能完成。
