Mengetahui spek RAM

Identifikasi RAM yang ada di komputer merupakan hal mutlak untuk penggantian, upgrade ataupun sekedar membersihkan RAM. Informasi awal tentang RAM bisa diperoleh tanpa membongkar komputer ataupun laptop. Hal ini sangat bermanfaat bagi pengguna yang tidak punya keterampilan bongkar pasang komputer. Apalagi kalau masih garansi, kalau dibongkar bukan teknisi service center resminya maka garansinya hangus.

Untuk mengetahui spek RAM mudah. Bagi slackers (pengguna Slackware) tidak perlu repot menginstall macam-macam. Tool-nya sudah tersedia.
