RamTest87+

This software tool will scan memory and look for errors. It's the only way to check the condition of memory in Simulation mode. Once this is run, the blue health bar for the memory will be displayed when you take it out and look at it.

In order to scan the memory, this program cannot be run from inside the operating system. So, this program requires a USB stick. Once installed on a USB stick, it can be used by inserting it into any computer that's not running, then select the Boot Selection button. When the computer asks which device to boot from, choose the USB stick with RamTest87+ on it.
