i have absolutely no idea whether this will help (or hinder) those with memory problems (touch wood i don't have them, thank goodness), but i suppose it might be worth a try.......
All of these RAM tweak programs are bs - they cause task manager to report more RAM available but can actually reduce performance. What they do is cause windows to move stuff from RAM into the pagefile thus more RAM is technically available but when a process needs that data it has to load from disk rather than be sitting in RAM already.
