Hvordan ser du informationer om RAM-hastighed og -type (line DDR eller DDR2 eller DDR3 eller DDR4) uden at \u00e5bne min computer t\u00e6nker du ? Jeg skal k\u00f8be RAM, og jeg skal kende den n\u00f8jagtige hastighed og type installeret. Hvordan finder jeg ud af ram-information fra en shell-prompt? Hvordan kan jeg tjekke ram hastighed i Linux?<\/p>\n

Du skal bruge biosdecode kommandolinje v\u00e6rkt\u00f8jet. Dmidecode er et v\u00e6rkt\u00f8j eller dumpning af en computers DMI (nogle siger SMBIOS) tabelindhold i et menneskeligt l\u00e6sbart format.<\/p>\n

<\/span>Du skal bruge biosdecode<\/a> kommandoen. Dmidecode er et v\u00e6rkt\u00f8j til at f\u00e5 informationer om din maskine hardware info DMI (nogle kalder det for SMBIOS).<\/p>\n

Linux check af ram hastighed samt type.<\/h2>\n<\/div>\n
\n

Proceduren er f\u00f8lgende:<\/p>\n<\/div>\n

\n
    \n
  1. \u00c5ben en terminal og login.<\/li>\n
  2. Skriv \u201csudo dmidecode --type 17<\/kbd>\u201d komandoen.<\/li>\n
  3. Se efter \u201cType:<\/strong>\u201d linjen samt for ram \u201cSpeed:<\/strong>\u201d<\/li>\n<\/ol>\n<\/div>\n
    \n

    \"\"<\/p>\n

    Lad og lidt mere detaljer om kommandoen.<\/p>\n<\/div>\n

    \n

    Installation<\/h2>\n<\/div>\n
    \n

    Brug apt command<\/a>\/apt-get command<\/a> for at installere dmidecode p\u00e5 Debian eller Ubuntu Linux:
    \nsudo apt install dmidecode<\/code>
    \nFedora Linux bruger, skriv denne kommando.
    \nsudo dnf install dmidecode<\/code>
    \nCentOS\/RHEL\/Oracle Linux bruger, k\u00f8r denne kommando     yum command<\/a>:
    \nsudo yum install dmidecode<\/code><\/p>\n<\/div>\n

    \n

    For at se ram hastighed og type p\u00e5 Linux.<\/p>\n<\/div>\n

    \n

    \u00c5ben en shell og skriv:
    \n$ sudo dmidecode --type 17<\/code>
    \nEller
    \n$ sudo dmidecode --type 17 | more<\/code>
    \nOutput:<\/p>\n<\/div>\n

    Du kan jo bruge grep med speed som argument som vist her (se grep<\/a> kopmmandoen) og skip alt andet info syntax:<\/p>\n<\/div>\n
