I still can't tell if there's an issue or not - you want Android to use RAM (rather than minimize usage) as long as it's not causing performance issues. So if it's using a lot of RAM but nothing is running sluggishly or force closing, etc then nothing is wrong with it. If it's using a lot of RAM and there are corresponding issues, then the issues should be troubleshot - but the screenshot doesn't show anything out of the ordinary - it's actually somewhat lower than I'd have expected.
