The program interface is simple and clean: it has several tabs where you can find CPU and RAM usage, plus the task manager, from which you can control all the active processes on your computer.
The program options, although slightly skimpy, let you activate interesting features like scheduled cleanings every so often or whenever the memory usage reaches a certain point.
RamCleaner is an interesting and useful tool that doesn't take up much space or resources. Definitely worth a look.
Trial version good for 15 days.
