The system always crashes when optimizing MT5 parameters.

 
The system always crashes when optimizing MT5 parameters.
I shut down many CPUs, but it still crashed.

Please post up your pc spec's, operating system, CPU resource monitor, and MT5 Build number to help us help you.

Backtest/optimization details would be helpful as well.

When you mention system crash. do you mean MT5 crashes or the computer itself?

A couple of years ago I had a an issue with my computer restarting during optimization. In my case it turned out to be a dodgy memory card.

What are you testing and where?

Could be low RAM, could be weak CPU? who knows? posting your computer specs would help you get a better answer though.
