轉自： linux內存測試工具memtester使用詳解

1. memtester下載

官網：memtester 官網

當前最新版本是：memtester-4.5.1.tar.gz
可以直接下載安裝包安裝，也可以通過wget命令下載

$ wget  http://pyropus.ca/software/memtester/old-versions/memtester-4.5.1.tar.gz

2. 解壓

$ tar -xzvf memtester-4.5.1.tar.gz

3. 編譯並安裝

$ cd memtester-4.5.1
$ sudo make
$ sudo make install

4. 使用

用於測試內存
i.g. 例如測試內存總量1900M， 循環測試10次

$ ./memtester 1900M 10

運行結果(沒有測出問題)：
