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.
