(@Señor CMasMas mencionou que poderia ser memória gráfica compartilhada, já que estou usando um iGPU, acho que pode ser o caso.)

Obrigado a @SeñorCMasMas e @NatalieAdams por me ajudarem a resolver o problema
O problema era que os 2 GB estavam sendo usados para memória gráfica compartilhada. Eu verifiquei isso alterando o tamanho do buffer no BIOS e diminuindo-o.
