Cek Speed dan Tipe Memory Ram di Linux Ubuntu

Bagaimana cara memeriksa kecepatan RAM dan jenis file (baris DDR atau DDR2) di Linux ? Anda perlu menggunakan utilitas baris perintah biosdecode. Dmidecode adalah tool atau dumping sebuah komputer DMI (beberapa mengatakan SMBIOS) isi tabel dalam suatu format terbaca-manusia. Output ini berisi deskripsi komponen hardware sistem, serta potongan informasi lain yang berguna seperti nomor seri dan revisi BIOS. Perintah ini bekerja di Linux, UNIX dan komputer BSD.
Buka konsol terminal dan ketik perintah berikut :

$ sudo dmidecode --type memory


atau

$ sudo dmidecode --type memory | more

Contoh output:

# dmidecode 2.9
SMBIOS 2.5 present.
