La reallotjament exacta realitzarà la realotització de la memòria addicional només fins al límit superior especificat.Quan passi el límit superior per a la memòria durant la reallotjament, les dades caixades es copiaran al disc si és possible.Quan passa el límit superior per a la memòria de disc durant la reallotjament, es llança l’excepció adequada.El rendiment ha de ser més alt si aquesta opció és desactivada ja que no es realitzarà cap còpia addicional si és possible,No obstant això, això també pot conduir a passar els límits superiors especificats per a la memòria o el disc.
