How to use more than 1gb RAM with Zenno poster

[gaabs]

I am getting at max 40 thread simutaniously I'd like to get more, I see that whats is blocking is RAM and after 25 threads it slowly opens others. I have 16gb RAM I believe I can open + 100 threads basing on other softwares I already used

Why do you think the program uses just 1 GB RAM? Please attach screenshots from task manager.
