Tarkka uudelleenjakelu suorittaa lisämuistin uudelleenjakelun vain ylärajan määrittämiseen asti.Kun ylitetään yläraja muistiin siirron aikana, tallennetut tiedot kopioidaan levylle mahdollisuuksien mukaan.Kun levyn muistin yläraja ylitetään uudelleenjakelun aikana, asianmukainen poikkeus heitetään.suorituskyvyn olisi oltava korkeampi, jos tämä vaihtoehto on suljettu pois, koska mahdollisuuksien mukaan ei suoriteta lisäkopiointia,Tämä voi kuitenkin johtaa myös muistin tai levyn ylärajojen ylittämiseen.
