Increase using all RAM

I have four 32GB RAM. While running the program, it uses only one. How is it possible to increase the speed of the processor by use all RAM?

More RAM does not help you to do anything if you have a small problem that is not bound by the amount of RAM. For example, suppose you wish to add two numbers.

x = 1 + 2;

How much extra RAM you have has absolutely NOTHING to do with speed of that computation. It is the processor that makes a difference here, not the amount of RAM available to it. (Yes, not all RAM is the same in terms of access time, but that was not the question posed.)

In your case, it appears that this extra memory you have was not needed, any more than it would be for the simple case I show above.

Dear John! Perhaps you know better then me what the amount of RAM i need for my tasks. Why did you bother for such serious answer.

Marika, please show the output of
