Linux 如何查看 系統硬體 的 詳細記憶體(RAM)資訊

在 Linux 要查詢記憶體大小, 可以用下述指令:

  • free
  • free -m
  • cat /proc/meminfo

    MemTotal:        8088504 kB
    MemFree:          337408 kB
    Buffers:          175136 kB
    Cached:          6873848 kB
    SwapCached:            0 kB
    Active:          4396244 kB
    Inactive:        3057212 kB

要查詢詳細的 RAM 規格, ex: DDR2、DDR3 .. 等, 可以用下述指令:

  • sudo lshw
