Linux 内存测试工具memtester安装与使用

转自： linux内存测试工具memtester使用详解

1. memtester下载

官网：memtester 官网

当前最新版本是：memtester-4.5.1.tar.gz
可以直接下载安装包安装，也可以通过wget命令下载

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

2. 解压

$ tar -xzvf memtester-4.5.1.tar.gz

3. 编译并安装

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

4. 使用

用于测试内存
i.g. 例如测试内存总量1900M， 循环测试10次

$ ./memtester 1900M 10

运行结果(没有测出问题)：
