There are a couple of things you can do to increase your RAM total so the game could eventually use more.

For instance;

- Reduce your textures, anti-aliasing and render distance in your GTA settings.
- Terminate unnecessary processes & programs running on the background of your computer using task manager.
- Give the gta-sa process a high priority.

It also depends on the server you are playing, if your client needs to load lots or few.

I don't understand why you wish to use less ram, more ram would be better.
