Eu uso o ubuntu 22.04 e tenho 16 gb de ram porém o ubuntu reconhece apenas 8, não entendo o porque ja q no windows ele funciona com 16 mas no ubuntu nao.
Quando eu vou ver as especificações do sistema ele aparece "memory 16 gib" mas quando eu abro o system monitor la aparece só 8,3gb rodando ( o q ta causando muitos travamentos aqui no pc)
Quando eu rodei o comando "dmidecode" eu vi o seguinte sobre as 2 memorias
