Have you installed/downloaded apps, games, widgets, etc? how many apps/services are you syncing? is your phone network branded? etc etc

This ram usage is normal for 4.3 because 4.3 requires minimum ram of 1gb and recommended ram is 2gb( as said by Google) this rom is actually made for xperia z and z1. Sony has ported this 4.3 for xperia t, TX ,v and SP. So don't worry about the ram usage,
