Točna ponovna raspodjela obavlja ponovnu raspodjelu dodatne memorije samo do gore navedene granice.Prolazeći gornji ograničenje za memoriju tijekom ponovnog dodjele, prikupljeni podaci će se kopirati na disk ako je to moguće.Prolazeći gornji ograničenje za memoriju diska tijekom ponovnog dodjele, ispušta se odgovarajuća iznimka.Učinkovitost bi trebala biti veća ako se ova opcija isključi jer ako je moguće, neće biti izvršena dodatna kopija.Međutim, to također može dovesti do prekoračenja gornjih granica određenih za memoriju ili disk.
