工具模拟RAM使用

Question

有谁知道一个工具，可以消耗一定量的Windows 7（64位）的内存？
我想在可用RAM变低时测试软件的行为。

在此先感谢！

由Sysinternals着名的Mark Russinovich提供了一个名为TestLimit的工具。你可以从：https://live.sysinternals.com/WindowsInternals/获得32和64位版本。

要分配1024 MB，你可以做到以下几点：

testlimit64.exe -d 1024 -c 1 

，并通过按Ctrl +ç结束它。

下面的命令行选项是可用的：

C:\Users\\...>testlimit64.exe
