Bagaimana cara memeriksa kecepatan RAM dan type-nya (baris DDR2 atau DDR3) 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 :
atau$ sudo dmidecode --type memory
Contoh output:$ sudo dmidecode --type memory | more
# dmidecode 2.11
SMBIOS 2.7 present.
