當機器在運行作業時,如何在不開蓋機器情況下查看記憶體規格以及資訊?可以使用以下方法:

安裝lshw:

Ubuntu/Debain:
apt install lshw

CentOS:
yum install lshw

執行查詢:

lshw -c memory

可以看到以下結果:

lshw -c memory

其中bankX:為DIMM槽位 我們則需要 product: HMA82GU7MFR8N-TF 這行

提取到Google搜尋:

即可知道廠牌


vmware:
使用Root登入之後執行指令:

vmware 5.0以前:
dmidecode|less

vmware 5.0以後:
smbiosDump

即可出現資料
