FM2+ AMD A10-7700K APUバージョンがあります。
4つの物理RAMスロットがいっぱいで、それぞれ4 GB、合計16 GB
SSDドライブ2台、120GB(OS含む)、256GBデータ
私は長年このコンピュータでCinnamon Mintデスクトップを実行してきました。
OSを搭載した120GBドライブを新しいデバイスに交換しました。
Mint 19を再インストールしましたが、うまくいきます。
これで、16GB RAMのうち6.9GBを使用する/システムのみが表示されます。
つまり、ターミナルhtop / topまたはデスクトップ「システムモニタ」を介して6.9Gibが表示されます。
奇妙なことは…
lshw6909MiBリターン
sudo lshw16GiBを返します。
メモリ全体を再利用できるように、この問題をどのように修正しますか？
関連診断は次のとおりです。

答え1
最後に...問題のメモリを別のコンピュータに交換しました。そこでも死んだ。これは物理的なハードウェアの問題のようです。どうやらSSDを交換しながらトーストをしましたか？奇妙な。助けてくれてありがとう！
