Hi. Few times a day a have huge screen lag. I Installed ram manager from Juergen app then uninstalled few apps which I don't use and still no changes.

Nothing wrong with your memory, thats how android works: http://www.androidcentral.com/ram-what-it-how-its-used-and-why-you-shouldnt-care
If you are using TouchWiz launcher, you can fix the lag by moving to other launcher (i suggest 'Nova Launcher'), using 'Greenify' to hibernate unused apps , or changing to another rom:
TouchWiz seems to work very smoothly on this one: http://xdaforums.com/showthread.php?t=2060403

get an app called disable service and another one called greenify..with greenify you can just hibernate a particular app if its running in background[user app in free version and system app in donation version]
with disable service you can stop google framework and services that are always working in background...but be very specific about disabling those processes coz some are important for play store functionality..

Maybe try a factory reset.. If it's so bad
