# Testing Ram and Cpu (Hardware)
|
|
|
|
There were instability problems on one of the hmi panel pc's related to ram.
|
|
|
|
To test Ram and Cpu for stability problems we use memtest86.
|
|
|
|
You can download it here: https://www.memtest86.com/download.htm
|
|
Then in the unzipped folder you have to flash the .img file to a USB drive with atleast 2GB of space.
|
|
We already have USB-Sticks flashed with memtest though.
|
|
|
|
1. When starting up the Pc mash Del (Entf in german) on an external keyboard and enter the bios
|
|
|
|
2. Select the Memtest86 usb stick in the Bios
|
|
|
|
3. Save changes and exit
|
|
|
|
4. Now memtest boots up, just let it do its thing from here
|
|
|
|
It works if the screen looks something like this:
|
|
|
|
|
|
|
|
Simply let it do one Pass ~20 minutes and shutdown and unplug usb stick afterwards
|
|
|
|
If it freezes completely -> unstable
|
|
|
|
If it shows errors the ram should be swapped out and the test repeated
