Yes, reality checks do not usually get you lucid, becuase most of the time you don't really remember to do them out of nowhere in a dream. they do however make you more aware of your surroundings, awareness in waking reality over an extended period of time leads to awareness at the subconcscious level and in turn in dreams, and when you become aware in your dreams, that is when you become lucid and THEN perform the reality check. So to the OP, you should not be so focused on remembering to do RC in dreams, you should focus on becoming aware of your surroundings in your dreams.
