记内存条硬件损坏蓝屏的 dump 文件分析

以下是我用 windbg 分析的两次蓝屏

第一次是用着 VS 的过程蓝屏了，我发现好多次都是使用 VS 蓝屏的，一开始还以为是 VS 投毒了

通过以上的 nt!KiPageFault 函数，即内存缺页错误堆栈，大概可以猜测和内存相关

也是挂在 KiPageFault 这里，证明应该就是内存相关问题。看到以上堆栈，只可以猜测是内存相关问题，不知道是驱动层问题，还是超频问题，还是内存条硬件损坏问题

在 lsj 的协助下，我使用了 TestMem5 工具进行测试，测试到了是一条内存条硬件损坏

拆掉损坏的内存条就不会蓝屏了

以上的蓝屏 dump 文件是通过在高级系统配置里面，点击启动和故障恢复里，配置系统失败时写入调试信息

在此之前我使用 Windows 自带的 控制面板\系统和安全\Windows 工具 的 Windows 内存诊断 工具都扫描不出来问题，这是因为此工具的内存压力不够大

这也就是为什么经常炸在 VS 的原因，因为 VS 给内存的压力足够大。使用 TestMem5 工具进行测试能够更好找到坑
