As the guide says, memory usage heavily depends on the type of attack you are performing. Actually the rule of thumb around here always was RAM >= total VRAM, not double, but I guess there is reason, why the guide says RAM >= 2 x total VRAM by now. Anyways, it should be fine to stick to the old rule, as long as you maintain the option to upgrade your RAM once you encounter such an error.

Feel free to post your reconsidered options, in case you are in doubt about anything.
