Linux 内存测试工具 memtester
作者:网络转载 发布时间:[ 2013/11/5 10:21:34 ] 推荐标签:
下载地址:http://pyropus.ca/software/memtester/ 有源码安装包、deb包、rpm包等。
源码已经编译好,只要make一下好了。
使用方法:
Usage: memtester [-p physaddrbase] <mem>[B|K|M|G] [loops]
如:
memtester 28G 3 #测试28G的内存3次。
因为系统运行和本工具运行都需要内存,所以不能把所有的内存都测试到。可以先用free 命令查看系统剩余多少内存空间再测试。
高级点的可以用-p参数从内存地址开始测试。

Stuck Address : ok
Random Value : ok
Compare XOR : ok
Compare SUB : ok
Compare MUL : ok
Compare DIV : ok
Compare OR : ok
Compare AND : ok
Sequential Increment: ok
Solid Bits : ok
Block Sequential : ok
Checkerboard : ok
Bit Spread : ok
Bit Flip : ok
Walking Ones : ok
Walking Zeroes : ok
8-bit Writes : ok
16-bit Writes : ok
结果全部为OK则内存正常。
